You and everyone else must be ready.

One Heartbeat Away – Reviews


“I picked up your book (One Heartbeat Away) at a thrift store a few weeks back, and all I can say is that you have completely changed my perspective on everything. I grew up in church but fell of track for many years. Still believed in Christ, but wasn’t living my life for Him. This book is absolutely life-changing. The way you described everything in this book leaves the reader with no other explanation other than JESUS IS KING!! Just wanted to say thank you for your words, your dedication to Christ, and that I can’t wait to see meet you in Heaven!” 

— Tyler F.

I just read your book One Heartbeat Away. It was amazing. The way you wrote it was enjoyable. I have to admit that some of the books I have read are like reading school books, They were hard to get through. Yours was so easy to read. I loved the stories—amazing. I have to admit that some of them even made me cry because they touched me so much. Thank you!” 

— Lisa F.

“A friend gave me your book, One Heartbeat Away, and even though I was forgiven and saved, it helped me grow in my faith! Since my pancreatic cancer diagnosis, I have been witnessing to everyone I know and some I don’t know. Your book has provided the arguments I would have had a hard time verbalizing.”

— James K.

“Mark, your books are wonderful and great for anyone, especially for Christians, to read.”

— Willard M.

“Last year, I wound up being incarcerated unfortunately but something that helped me through, other than the Bible, was your book, One Heartbeat Away. How you blended science and religion truly blew my mind. I gave my life to Christ at age 14. I’ve tripped up time and time again, but it finally caught up to me. Prison really banged me up. I’m still recovering over a year later. Just wanted you to know your book really encouraged me to get my life back together. It was the perfect aid with God’s Word to get me back on track! So, thank you, thank you, thank you, sir, I hope to one day read One Thing You Can’t Do in Heaven. I really struggle with witnessing after lockup. It’s hard for me to open up to people but if One Heartbeat Away was good, I can’t imagine how helpful it would be to my walk. You’re a great writer. I loved the bit about you and Charles Barkley – amazing! Be blessed my guy.

“My friend told me about this book. Being the skeptic that I am, I said the usual, “Yeah, okay. But hewas persistent, so I finally did read One Heartbeat Away, and I read it again, and I read it again, and now, I am reading it again. I would say that this is probably one of the best, if not the best book that I have ever read. I highly recommend that EVERYONE read this book.

 — Garland D.

One Heartbeat Away is the best book of all time. It is really inspiring.

One Heartbeat Away is near the top of my top ten books! Every Christian should definitely read this book!

 — Don S.

“I am now a retired Deputy Sheriff from NY. Every law enforcement officer in my area received One Heartbeat Away and One Thing You Can’t Do in Heaven thanks to your ministry! A past Marine and I (Army) are joining forces and to evangelize two towns, in Christ’s Holy Spirit power, with in the remaining time He gives us. My Dad has come to salvation in 12/2018 from opening/reading/repenting/confessing after reading One Heartbeat Away. PTL!!! Love you, Brother, and your team!!

 — Brian T.

“I received a copy of One Heartbeat Away in prison, and it changed my whole way of thinking. It’s like the words were just jumping off the page. I read it at lockdown. It took me two nights. I considered myself blessed to have received it since it was filled with so much valuable information and subjects I’m all passionate about. Plus, I received the only copy in that whole prison. I did ponder on how this got to little old me all the way over in New Zealand, and I could only say it was God’s doing.

 —Kotuku W.

“My co-worker shared his copy of One Heartbeat Away for me to read. I was born Hindu and accepted Lord Jesus after marriage. After 23 years of being baptized, I am only now beginning to understand what I am supposed to be doing as a Christian. One Heartbeat Away helped me realize I have been doing nothing. I am praying to the Lord that he may give me strength, make me bold, guide me in the right direction. I want to read all your books and share it with as many people I can. I am in the process of listening to your sermons too! With sincere thanks.

— Joshna P.

“I received a copy of your book One Heartbeat Away from my friend and I just want to let you know that it is probably the best put together bit of material I have ever read. You did a truly remarkable job of explaining almost everything pertaining to life, salvation, and eternity.  I read the book twice.  You are just about the most amazing evangelist that I have ever come across and I am 70 years young.  Keep on keeping on. Also, I can hardly wait to read your book One Thing You Can’t Do in Heaven.”

— Garland D.

“Everything is written so beautifully and intricately in this book (One Heartbeat Away) and only a person who does not want to see the truth will finish the book and still say God isnt real.”

— Narin J.

“FORGIVEN! Great book, Mark! I look forward to sharing it with others who I know are certainly either on the fence or on the wrong side. To me this is a perfect book for someone to pick up who has questions about God or who’s never read a single line of scripture. Be well.”

— Josh T.

“I enjoyed One Heartbeat Away so much that I will listen and read it again. The other audiobook (One Thing You Can’t Do in Heaven) helped me to spread the gospel with more confidence. What you are teaching through the books has propelled me in a very positive and responsive way. You gave me a lot to think about. I’ve already made some adjustments in reaching the lost, and I will continue to do so.”

— Martin K.

“Thank you, Bro—Mark for the book One Heartbeat Away. I was blessed, and tears fell down my cheeks every time I read every page. I want to share them with my family and friends who are not yet believers. Thank you.”

— Eduardo Chan

“Your literature has brought to my attention new scriptures for witnessing. Yes, I know that these scriptures have always been there, and I have read them many times, but just here recently, they have been revealed to me as witnessing scriptures. They are new tools in the tool box, my friend.”

— Danny G.

“I’m trying to do a little evangelism for our church here in Florida. I’ve been witnessing in a couple of shopping plaza parking lots for the last eight years, after reading your book The Watchmen. I contacted you a few years ago when I was involved in the jail ministry, and you sent the jail a couple of cases of your different books.  The inmates were really happy, and I really distributed One Heartbeat Away to a bunch of them, and it was the most read book on my Christian book cart.”

— Stephen B.

“Your books One Heartbeat Away and One Thing You Can’t Do in Heaven, I have read several times. They have the effect of drawing me closer to God and recommitting to serve Him more faithfully each day. Congrats on reaching the milestone of 1 MILLION copies. Keep on fishin’, Brother!!”

— Dave S.

“One of the greatest evangelical reads you will ever hold in your hands.”

— Joshua M., Pastor

“Last week, I gave one of your One Heartbeat Away books to an inmate at the jail I am working with. I met with him again today, and he said, “I love what I have read so far. I am really into science, so I read chapter two twice.”

— Nile A.

“We are almost finished with your book One Heartbeat Away in our men’s group. Your Study Guide questions and answer key have been perfect for our hour-long meetings each week!”

— Jimmy D.

“There are 7 billion on the planet. We need to keep sharing and handing these books out. One Heartbeat Away is the most impactful book I have ever read; other then the Bible.”

— Dave F.

“l just received a copy of your book, One Heartbeat Away and am half way done with it. I can really say that this book has enlighten me. My sins had blinded me so badly that l couldn’t notice them. And I just want to say  “Thank you” for showing every lucky person who has this book the true way to eternity.”

— Edwin A.

“My sister passed away 5 weeks ago. In her most uncomfortable moments, she accepted Jesus as her Savior. My two teenaged granddaughters listened to their aunt’s profession of faith with tears running down their cheeks. We miss her, but the sting is a little easier to bear knowing that she is in Heaven. Without studying your books (One Thing You Can’t Do in Heaven and One Heartbeat Away), this wouldn’t have been a happy ending! Thank you a million times over.”

— Penny L.


“Your books are definitely the best books we have read on the subject of witnessing.”

— Penny Jo L.

“An 83-year-old ex -marine is currently reading One Heartbeat Away. He was talking about reading your book and said how plan and simply it was written.”

— Jennie T.

“Twelve years ago, I read both of your books One Heartbeat Away and One Thing You Can’t Do in Heaven. Since then, I have gone to Bible college and witnessed to hundreds of people and seen many saved. I was saved before I read your books, but my heart was change in a radical way to witness and be the servant God calls us to be. Thank you for allowing God to control your life. Time is short, and now is the time to serve and dedicate our lives to Him.”

— Dillon P.


“I have read One Heartbeat Away and One Thing You Can’t Do in Heaven. I not only learned a lot, but I’m pumped up about witnessing to people everyday. Love to ask people many of the questions mentioned in your books. I also am sharing your books with my LIFE group at church.”

— Richard Q.

“I am a full-time chaplain down in Florida, and you have sent us a bucket load of your books couple of times now. The inmates love them! I am hoping to get more, if that’s possible. We give them free to inmates here, and they almost always ask for more after they’ve read one of them.”

— Chaplain Buddy B.


“Just wanted you to know that I am on the road a lot. Every day, I listen to your audiobooks over and over. I am so fired up about sharing the information you have taught me and the proper way to present this information. I now have no interest in listening to music; I’m just interested in making an eternal difference. I feel like I am a part of your army, battling to save the lost.”

—Mark M.

“Hello, Mr. Cahill. I say “Mr.” out of my deepest respect for you. I just finished your great book One Heartbeat Away and it gave me a new understanding of what God wants us to do with the rest of our lives. Or, I should say, our remaining time on this earth. After finishing it, I felt like I had butterflies all over my stomach and heart. What a great feeling. I told several people about your book, and they ordered it right away. I love the way you explain everything in terms that everyone can understand. I am going to order your book One Thing You Can’t Do in Heaven next week so that when I start talking with others, I will have a better understanding of everything I should say. I don’t want to start talking and say something that may drive them towards the
dark side. Thank you, again, for the wonderful book you wrote. May God Bless you always.”

—Phil B.

“Your books are so easy to read and make it so obvious that we really have no excuses for not telling others about Jesus. Love that they are packed full of examples and ideas! Thanks Mark!”

“I found your book, One Heartbeat Away: Your Journey into Eternity, at a thrift shop. At the time, I was living in sin and backslidden. After reading your book, I became extremely convicted and immediately dedicated my life to Christ and stopped my sinful behaviors. As a result, God has worked miracles in my life!! God always gets the glory! He’s using you to change lives for all eternity. I want to express my heartfelt gratitude for your dedicated work for the Kingdom of God. Thank you so much! God Bless You, Mark Cahill!!

—Allison L.

“You gave me your book, One Heartbeat Away, at a friend’s birthday party. It was one of the best books I have ever read, and my son has it now. I’m looking forward to reading the next one, One Thing You Can’t do in Heaven.


“I was not a believer at the time you gave me One Heartbeat Away. I was a hard atheist with a hard heart for most of my life but came to know the Lord Jesus Christ in the summer of 2020 after reading the Gospel of Mark. In looking at your book recently, I think it is a great tool for apologetics and evangelism. You are an encouragement by your obedience in sharing the gospel with strangers like myself.”

—Jonathan S.

“Your book (One Heartbeat Away) is one of the most awesome witnessing/evangelism tools around for both non-believers and believers.”

—Bob H.

“My mom isn’t a born-again Christian. I gave her several of your books for her birthday. She is on chapter 11 of One Heartbeat Away and said it’s an awesome book. I said, “Wait ’till you start One Thing You Can’t Do in Heaven.” Every chapter she has finished, she loves. My stepdad also loves the book as well.”

—Eric M.

“Your book has radically changed my life!! I was a backslidden Christian living in sin. I found your book at a thrift shop. After reading it, I felt extremely convicted! I immediately made significant life changes for the Lord! I’m so incredibly thankful for the Lord working through your writing! I’m no longer living a sinful life, but a faithful one! All glory, praise and honor belong to God Almighty!! I wanted to let you know what an impact that your book has had on my life. Thank you so much, Mark!! God bless you!!”

—Allison L.

“Mark, I’ll tell you what, One Heartbeat Away made me think. Now, every time I am out, I mention Jesus. Or, I just ask someone if they have ever thought about what comes after death. I now understand the urgency to find souls for Jesus. I really did not understand what Jesus meant by “fishers of men.” My understanding had been to get bodies in church. Then, later in my walk with Jesus, I understood that it meant fishing for souls, but I never had an urgency to find souls. I do now because of One Heartbeat Away.”

—Michael W.

“For 69 years, I threw away any unsolicited religious literature until my friend in Iowa sent me One Heartbeat Away! Just a few pages in, I became engrossed. It answered all my questions about God and the Bible. It substantiated everything scientifically, historically, and archaeologically. I was dumbfounded as I kept muttering to myself, ‘Wow.’ My closed mind was awakened by this book! I never liked who I saw in the mirror and now I say, What a beautiful person God created who Jesus loves just the way she is. Thank you!”

—Jean M.

“I recently had the uplifting experience of reading your book, One Heartbeat Away. It was sent to me by someone I have great respect for. Your book took my mind places it had not been before. Your words will stay with me. My friend also sent two of you other books, Reunion and Paradise, which I look forward to reading.”

—Jerry R

“I was a hardcore atheist until I read One Heartbeat Away.”

—Josh R

One Heartbeat Away is a great book.”

—T Sapp

One Heartbeat Away is what lead me to Jesus. I was an atheist. After I read it, I got born again. That was 7 years ago.”

—RFS Tables

“I am almost done with One Heartbeat Away and have learned a great deal from you. I have already put the ideas and sound logic into use with others. I have given several copies of it away, so far, and will continue to do so. I am a raving fan of this book!”

—Shren Y.

“One Heartbeat Away is an amazingly well-researched and eye-opening book. I love truth, and this gives me the tools I need to have fact-based conversations with God-challenged friends. One thought struck me as I thought about the cause and effect of life: “I thoroughly agree that there must be a cause to an event like the big bang. Chance cannot explain it.” That said, what is the cause of God? We are clearly told in the Bible that God existed before form and light. Could create some circular logic. Blessings and great thanks!”

—Hal Y.

One Heartbeat Away was shared with me by a 67-year-old friend who has spent the past 7 months in jail awaiting trial for allegedly killing another man. He has alcohol and drug dependencies. With much time to reflect on his life, he was so convicted by your book that he purchased a bundle to share with others. It is a marvelous book. THANK YOU!”

—Peggy W.

“One Heartbeat Away is still one of my favorite books!”

—Jeremy R.

“One Heartbeat Away is a great book!”

—Melanie M.

“There are two types of people in the world: those saved and those unsaved. For the latter, One Heartbeat Away is a must. For those who are saved, One Thing You Can’t Do in Heaven is a must. I am so thankful for these two easy-to-read books.”

—Scott S.

“Fabulous book! A subject matter similar to Mere Christianity but much more reader friendly and better designed for our current society.”

—Darla M.

“Greetings! My name is Nick. I’m born-again in Kenya, the land blessed with great long distance runners. Just letting you know that I stumbled on your book One Heartbeat Away, and oh my! I have not put it down. I have been blessed by the awesome insights I have received therein. May God grant thee more grace. Thank you & God Bless.”

—Nick K.

“I just got out of a tiny grocery store where the cashier didn’t believe in God. I gave him One Heartbeat Away and told him, “By the time you are done reading this book, you will believe in God!” He took the book and immediately started looking at it. Every time I serve Jesus, I get this happy feeling in my heart. Have a great day!”

—Corinne K.

“My sister gave me a copy of your book One Heartbeat Away and asked me to do her a favor and read it. I started reading it and found it very hard to put it down. I cannot explain the impact it has made on my life. After reading your book, there is absolutely no doubt in my mind about the truth.”

—Jeff M.

“At 83 years old, I can tell you emphatically that One Heartbeat Away is the best book I have ever read in my life!”

“One Heartbeat Away is life changing. Absolutely awesome.”

—Joni F.

“I can’t thank God enough for having given me the great privilege to come across your book. I won it in a book auction, and am I exceedingly glad I did! Heaven? Yes! I am from Nigeria, Africa. I just put down your book One Heartbeat Away minutes ago. I have been so richly blessed by it. It is an answer to my prayer that God has so kindly granted me. Please keep up the good work. Your books are touching so many lives. What a harvest you’ll reap in eternity! God bless you, dear Mark.”

—Askia Q.

“I’ve been a Christian for over 20 years. I came to Christ out of Judaism in my 40s. This book [One Heartbeat Away] has left me more prepared to speak to those who might be searching. Everything you stated, every question you posed, every scripture you cited was right on the money!”

—Jeff C.

“I am so thankful for how God has used you to impact both lost souls and saved believers like me for Christ throughout the years. One Heartbeat Away has been so helpful to me and those around me. I have shared this book with various lost individuals, including a Muslim, and one guy who has trusted Christ as his Lord and Savior and is currently in our church’s discipleship program for new believers. Thank you!”

—James N.


“We listen to your CDs while we are driving. What a blessing. Every human being should get to hear One Heartbeat Away.”

—Walt C.

“I just read One Heartbeat Away again for the fifth time. It really is uplifting. I emailed you several months back and requested ten copies of that book. I received them and gave them to individuals I felt would be touched by it. I know for sure two of them have accepted Christ. So, the seed that you gave me with has done wonderful things. God bless you for your ministry and all you do.”

—Randall S.

“One Heartbeat Away is an amazing book! I’ve never felt more passionate about sharing my faith and sharing everything God has done for me. Now, I’m longing for those meaningful conversations about Jesus. I just want to talk about life and all its beauty! I have a lot of non-believing friends, and the facts in this book are things I can really use! It has opened my eyes on a lot of subjects, and I cannot wait to share this book with so many people!!”

—Madison A.

“Just finished reading One Thing You Can’t Do in Heaven and I’m currently reading One Heartbeat Away. Love your books. They really put me my faith in Christ on my feet!”

—Kelly H.

“I love these books!! One Heartbeat Away is chock full with ways to talk to the lost. I highly recommend it!! These books are easy reads, great stories, and challenge you to step out in faith to tell other’s about Christ. They have truly inspired me to be able to share the Good News of Jesus Christ.”

—Yvette C.

“I think everyone should give a copy of One Heartbeat Away to their non-believing friends and family. It contains compelling science that supports a Creator’s an intelligence behind the design of man, nature, and the universe. Mark Cahill takes the existence of God from a leap of faith to an absolute logical conclusion. Brilliant. He propels Jesus above all others, as fulfilling the law of God, and, more importantly, as the ONLY chance we have at salvation. This book really creates a must for the reader. Again, brilliant.”

—Ted M.
Book Review

“Thanks for all that you do, Mark! I was that lukewarm Christian, even though I surrounded myself with strong Christians. It was your book One Heartbeat Away that drew me back 100 percent. I have given away at least a dozen of these books.”

—Kevin H.

“I bring you greetings in the name of our Lord Jesus Christ from Ghana, West Africa! I am the founder of Christ to the Nations Outreach Ministry. I would like to thank you very much for the impact you are making in the Kingdom business. I read your books One Thing You Can’t Do in Heaven and One Heartbeat Away: Your Journey into Eternity. These have really built my faith and have equipped me in my area of calling to evangelize the world for Christ. I was really blessed by the argument you shared in your book about the existence of God and evolution. I thank you so much for writing these books. I can’t tell how much it has transformed my life. God bless your ministry and your labor in the Lord.”

—Sylvester S.

“A good friend sent me your book One Heartbeat Away, and it was pivotal in leading me closer to Christ! I have always been a follower of Christ, but like so many so-called Christians, I allowed myself to be on the throne all too often, failing to fully submit myself to the Lord’s true calling for my life. Your book drove truth into my soul. I give out your book to all of my doctoral students and friends.”

—Derek S.

“One Heartbeat Away has turned my life around.”

—John L.

“One Heartbeat Away is truly one of the most complete, definitive books for the gospel that I’ve ever gotten my hands on. I LOVE sending it out because, next to the Bible, it is the most effective book I send!!”

—Jo Anna W.

“Just wanted to let you know your book One Heartbeat Away was one of the linchpins in me going from atheism to being born again. I found your book when I was facing life in prison for a 30-man street fight when I was just 18 years old. It was finally logic and answers to the tough questions that plagued me for so long that helped. I spent a year of my life behind bars, and never did I feel so free after experiencing Jesus. I am now free from jail and have had the opportunity to share my testimony with over 150 K high school kids all over the nation. It is truly a shame that publications like One Heartbeat Away aren’t more main stream. The world needs this kind of material. Thank you for being obedient to God’s voice.”

—Dr. Pain

“I have just finished your book One Heartbeat Away and wanted to share my experience. I came across your book at our Senior Citizen Center, where we check out books at no charge. We share any books we have that we want to donate. I couldn’t put your book down. I couldn’t read it fast enough! It will be no surprise to you to learn I have already ordered your other book, One Thing You Can’t Do in Heaven. I anticipate it arriving this week so I can get started on it.”

—Janice B.

“I’m going through One Heartbeat Away with my friend, chapter by chapter, week by week. We are up to Chapter 9. She doesn’t believe, but she says she is learning a lot and getting a clearer picture of things, even though she doesn’t believe it. We have a very pleasant time together, and she keeps coming and wanting to discuss it. I appreciate your step by step approach. The chapter on repentance was very clear. I’m praying for boldness to engage with others, too.”


“Hi…my name is Mike….I was recently incarcerated in Harrisburg, PA….I had the opportunity to be blessed by reading many of your books….you are gifted in a way with your writing skills because once I opened any of your books, I couldn’t put them down, and it’s not easy to keep my attention….I want you to know that One Thing You Can’t Do in Heaven was the first book of yours that I read, and it has greatly inspired me to spread the Word. I hope to meet you someday….I have family in Georgia, and I think, if I recall correctly, that is where you are from…..keep up the great work you are doing, and just know that you have reached 1 more person’s soul. GOD BLESS!”


“A few days ago, I gave my piano tuner guy your One Heartbeat Away book.  He said he was very interested in proving evolution is false but didn’t want to read anything about salvation. I told him to take the book and read as much of the book as he would like, and it would be okay with me if he didn’t read the whole thing. So, he took the book. A couple days later, I called him back, and he said to me, “I am almost done with the whole, entire book. I love it!! It’s great!! Very well written.’ Your books are changing people’s lives and eternities. Thank you!”


Mark! I ordered two boxes of your books a few months back. I read One Heartbeat Away, The Watchmen, and Ten Questions for The King. Life changers! I have to say that these three books helped to turn me on to the path of obedience to God in sharing my faith. The Spirit really worked on my heart and mind through these books. I just wanted to stop and thank you for your time and effort in writing these books. The Lord is leading me to New York City; I can’t wait to stomp those streets and tell people about the only Way, the Truth, the Life! What a calling. Endless possibilities to share. What a gift!”

—John K.

“I’ve read your books. Honestly, I can say I was impacted. In all of my 30 years, I had never been in contact with a Bible, let alone understood it. I believe that if it wasn’t for your book, I probably wouldn’t have understood it. One Heartbeat Away opened my eyes to believe more in God and less in science. I’ve always been more of “facts and proof” guy, but your book opened my heart to God. Thank you! God bless!”

—Salvador T.

“Well, I am on page 42 of One Heartbeat Away, and, so far, I’m digging the science. I love it. You are totally disproving theories left and right. Slam!! Looking forward to where this book is going. Very well thought out and well put. Hard to disclaim. This book is exactly what I needed.”

—Melissa S.

—Andrea R.


“We were able to deliver 900 copies of One Heartbeat Away and 850 copies of One Thing You Can’t Do in Heaven to over 900 pastors in the Coban region of Guatemala. These pastors are from many different denominations, but they all are committed to read through the books and begin using them for evangelism training and outreach. God is using this material to win the lost and disciple believers.

“Thank you so much for making your audiobooks!!!! In two days, I have listened to all of One Thing You Can’t Do In Heaven and most of One Heartbeat Away!!! I love them!!!! I love the content and the way you read!!!! So faith building!! The audiobooks alone, for me, have taken my passion for fulfilling Mark 16:15 from 75 to 99 10---One-Heartbeat-Awaypercent. I am a carpenter by trade, but when I have half a chance, I go find people to share the good news with!”

This church in Nicaragua loved receiving One Heartbeat Away in their native language! Both One Heartbeat Away and One Thing You Can’t Do in Heaven are available in Spanish, which is good to give to Spanish speaking people in our nation as well.


“My name is Jesse and I live in Durban, South Africa. I am 56 years old and was born into a Christian family, so I practically grew up in church. I am of Indian descent, born in South Africa. I am an avid reader and have, over the years, read many thousands of books, both spiritual and otherwise, but never have I read one as informative, encouraging, and challenging (apart from the Bible) as One Heartbeat Away. It has changed my perspective of the Christian approach to evangelism. I intend to buy many copies of this book and give it to everyone I know (and don’t know) so that they, too, can be challenged when confronted with the truth! I thank God for you, and I hope that when you plan your travels, you would have my country in mind. We need someone like you to minister and teach us. I would gladly host you should you ever visit our shores!”

“About this time a year ago, my ex-husband came from Dallas to join a birthday celebration with our three grown children and their kids in Salt Lake City. I gave Kerry One Heartbeat Away with the promise that he would read it. I thought the fact that you played basketball at Auburn and hung out with Charles Barkley would entice him, since he’d had a great four-year basketball career at the University of Kansas. I knew with all the stories in the book that included athletes, he’d enjoy the read. But, best of all, I wanted him to give his relationship with God a fresh look. Unbeknownst to us all, he had been diagnosed with a tumor on his lung. I believe he was seeking answers to the questions we all ask when facing death: “What is next? Is there a Heaven or Hell?” And, I think through your book, God graciously led him to the right answer: faith in Jesus for his eternal salvation.

You see, on October 1st, Kerry had a stroke while driving to his last chemotherapy appointment. He sustained too many injuries to survive the ensuing car accident and passed into eternity on Oct 14th. But he was aware that his whole family was gathered around him. He heard them all praying for him. The surgery team even texted the family four times during his six hours of surgery that they were praying and wanted the family to keep up their prayers as well.

The way God has used your book didn’t stop with him. After he died, my daughter, Kelly, was terribly distraught, fearful that her dad might not be in Heaven, until the stories began to surface. She found out about the impact One Heartbeat Away had on him. He had kept his promise to read the book and insisted that his Christian sisters-in-law also read it so he could discuss it with them. They told him the book was absolutely correct. So, I gave my daughter Kelly your book, so she could read it through her father’s eyes, and her heart was opened to the Truth, as well. Then I sent copies to all of Kerry’s other five children and five brothers and sisters encouraging them to also read your book through Kerry’s eyes. God knew the timing and orchestrated everything so that not only Kerry, but his whole family would know Jesus and His offer of eternal salvation. How lovingly God has worked through all of this. Thank you, Mark, for writing this amazing book that explains the gospel so clearly. My heart is so full. I gratefully keep you and your ministry in my prayers!”

“I have taken to your great book One Heartbeat Away: Your Journey into Eternity. What a great book it is! It is a great pearl for me. I have studied it very carefully. I have known many and many great deeper truths from that book I have never seen from such kind of a book in my life. I pray for you and praise and thank the Lord gave to you a great burden of heart about the lost human race.”

“Yesterday, I received a phone call from one of my friends who is working as manager in central government. His name is Mr. Chundren. He is residing ten miles from our church. He invited me to his house for an important talk. I went to his house, and as we were talking, he was crying with so much tears. I said, “Why brother you crying? What happened?’ He said I was so foolish so far in my life without knowing the true God and eternal life. He told me, “You gave me a book called One Heartbeat Away, Your Journey into Eternity.‘ He said, “That book has opened my eyes to know the truth about God and eternity. I want to learn deep in God’s Word and to became child of God to inherit the kingdom of God.’ Mr. Chundren requested me to have Bible study every week in his house. We greatly accepted to have Bible study in his house, and also I gave him one full Bible, and he gave the same book to other friends who are working with him in the office. Because of him, the whole family got saved, and he is trying to share about eternity to his friend also in office and relatives. He said that, so many years I went to so many holy temples, and did all welfare to the poor in order to get place in heaven, but after reading this book, I came to know that all these things will not take a person to heaven. We give all the glory and honor unto God, we are so happy to see the work of God through the wonderful literature evangelism.”

“Here’s a short story on the impact of Mark’s book in my life. I have a friend, his name is Jeff. One day, he said something that stuck strongly in my mind and still sticks. Paraphrasing it, he said, “I don’t want by the time I die, all I believed is false.’ It does make sense since it is not a matter of what I want to believe but whether what I believe is true. And Jeff is the one who recommends Mark’s book to our church, The Mission. Every Sunday, we have free books to give away in our church and one of them that is always in stock is One Heartbeat Away. I also managed to recommend the book to my company via our company’s newsletter.”

—N Yodo

“Have to say, I just finished reading your second book, One Heartbeat Away, and was absolutely astounded and amazed. Anyone, Christian and non-Christian needs to read it. Phenomenal book. I have zero percent doubt of anything in my faith, and I am amazed by some of the experiences you talk about. Thank you, Mr. Cahill, keep up the good work!”

—B Walker

“I am not even fully done your book, and it has already awakened me. I can’t believe how lost I have been in my life. I honestly thought there was no hope for me because of all the sin I had committed in my life. I am so thankful for your work, and God’s work. I would have never guessed that I would be a believer in Christ at all. I am still struggling to find absolute truth, as you stated in your book. I am still in “search mode,’ but, at least now I know that truth is out there. Thank you for the work and passion you put into writing this book. I know that I am not the first person whose life has changed because of it, nor will I be the last.”

—T Brown

“The inmates in solitary at an Ohio prison got One Heartbeat Away and One Thing You Can’t Do in Heaven a few weeks ago. One of them told me these were the BEST books he has ever read! (He has not read the Bible yet!) These books and God truly change lives. Mark, you have a huge heart for those that are incarcerated! Keep up the good work and huge THANKS!”

—M Carter

“I was lost and on the highway to hell until I read Mark’s book One Thing You Can’t Do in Heaven and learned that I was breaking every commandment in the Book. I gave my life to Jesus and was baptized last Sunday. I bought One Heartbeat Away where I again gathered some great talking points, and recently gave my testimony to a close friend, telling him we are both ‘one heartbeat away’ from Judgment Day. Rick told me after the conversation that he was a backslider, and Sunday morning he is going forward to rededicate his life to Christ and wants to be in Heaven. Unreal. The title of the book says it all.”

—M Morgan

“So far, One Heartbeat Away has strengthened my faith and reinforced the fact that there is a heaven and hell. I don’t see how anyone can read this book and not see that there is a creator GOD who sent his Son to die for the sins of the world. It is the best apologetics I have seen or read. In the future, I am hoping to get a box of the new book and the old book to give out to people. Keep up the great work, Mark!”

“Since reading One Heartbeat Away, I have, in the first 2 weeks, not only changed my life; but also those of the people around me. I have stepped out and talked to more than 20 people and had 7 of them come to church with me. Thanks, Mark, for your inspiration and encouragement.”


“My 78-year-old mother professes to be a Christian, but I felt that she still didn’t understand salvation. She was looking for something to read, and I recommended your book One Heartbeat Away. She finished it in two days, loved it, and now understands the purpose of Jesus’ life and death. Thank you for writing your book in such an easy-to-understand tone!”

—C Northcutt
English Teacher

“I just finished reading One Heartbeat Away and will be placing an order for 5 books to share with co-workers. I led one co-worker to Christ a week ago. Your book is thorough, relate-able, and practical in answering many common questions and overcoming obstacles for persons inquiring about Christianity and the Bible. I am excited about the new work of grace in my heart as I have understood with fresh conviction of the reality of hell and the need for everyone to be warned and genuinely invited and persuaded to embrace the gospel. My visit with you and your new book were timely and significant in giving me the boost I needed to be faithful to Christ and my destiny. Thank you for your obedience and passion.”

—D Groff

“One Heartbeat Away is an AMAZING book, and I really recommend reading it! It is a powerful tool/resource to use in leading your friends to Christ!”

—S Bruce, 15 years old

“I’ve read both of your books, One Thing You Can’t Do in Heaven and One Heartbeat Away, Your Journey into Eternity. These are both awesome books. I really admire the knowledge you have when witnessing. Satan has a lot of people tricked into believing his lies and, therefore, denying the truth! Your books have given me tips to use when witnessing. Thank you! I also had a one-way ticket to hell canceled by the blood of Jesus!”

—D Manning

“I cannot recall how many people I have witnessed to, but I can tell you that in EVERY situation, I use the Word of God and the material covered in Mark Cahill’s book! One Thing You Can’t Do in Heaven and One Heartbeat Away are two “must have’ books for all Christians who have the burning passion and zeal for evangelism.”

—R Klave

“Having been raised in the Mormon cult, I’ve been searching for an effective witnessing tool to reach my family. Mark Cahill’s One Heartbeat Away is just such a tool! My Mormon parents were the first to receive a copy.”

—A Mehlisch, 43
Letter Carrier

“In November of 2004, I heard Mark Cahill speak. I quickly read One Thing You Can’t Do in Heaven twice. I have witnessed for the Lord since Jesus tackled me over forty years ago. Since then, my witness has increased exponentially and I enjoy it much more and with less intimidation. I am seeing the many hearts out here that God is working on. One Heartbeat Away is more faith and courage nutrition and is evidence that the Holy Spirit is using Mark Cahill in advancing the mission of Jesus Christ.”

—V Costa, 68

“Just want you to know that I loved the way you wrote One Heartbeat Away. Written specifically for the lost and searching, its style equips the believer with solid Christian apologetics. This book is a real one-two punch. Also, the title is BRILLIANT! It grabs one’s attention immediately because eternity is ever on the minds of those God is drawing.”

—S Kalman

“While I was reading your book, the subject of how we can prove that the Bible is truly the Word of God came up in my Sunday school class. The Lord reminded me that I had your book with me in my backpack and about all of the information you had written in the first few chapters about this very subject. God directed me to give the book to the individual who had the questions, even though I had not yet finished reading it, and now, I have to buy another copy when I have the funds available so that I can finish reading.”

—J Clark, 30

“A group of us from work (two men and two women) flew to Providence, RI to attend the memorial service (in Boston) for the only son of our former boss. All of us were thinking about eternity that day. Our trip included an hour-long drive to and from the airport, and I used the occasion to give each member of the group a copy of your book, One Heartbeat Away, and talk through the issues of death, faith, and the afterlife. One of the women is Catholic but not saved: she had lots of questions about just what the Bible teaches. Your book was a wonderful evangelistic tool, both to support our discussions and as a resource for them after the trip. My Catholic friend was leaving for vacation in the Bahamas the next day, and promised to read through your book before she returned. Thanks for all that you do!”

—D Pyle

“Great book! One Heartbeat Away uses apologetics as a means for evangelism instead of just winning an argument. I used some of the facts from the book in a conversation with some atheists online. It really gave them something to think about. I’ve read several books on apologetics but, until now, have not had any that really contained all of the points that I thought were exceptional AND were in a really readable format and also has a strong gospel message. I own two Christian bookstores and will be recommending your new book to everyone who knows someone who is a skeptic.”

—B Venable

“The book [One Heartbeat Away] that you gave to me has explained to me all of my questions about “afterlife’ and eternity itself. Yes, this book has become my “journey into eternity.’ I find it fascinating to go over its pages”

—V Kotorova

“I am a Christian and I read the book One Heartbeat Away and use the information to witness to others. I talked with someone for about 2 1/2 hours using your examples in the book for proving the Bible is true and that there is a God. After talking with him for that long, he got saved and it was an answer to prayer. I will continue to evangelize and use your examples and tips because they are so helpful. God Bless!”

—M Jimenez, 14 years old

“Thank you for your book One Heartbeat Away. I was truly impacted by the results of the pulmonary surgeon’s interviews with people who had died on the operating table and had been revived again. It is very troubling to me that about half of those who have had a near-death experience saw hell. Even more so, is the fact that those who saw hell did not talk about it again for a couple weeks after their dreadful experience. The thought of so many people seeing hell will continue to be a vivid reminder to me to witness whenever I am able.”

—Pastor B Aldrich
Witness, Mentor, CrossPollination Ministries

“I saw you speak at the Worldview seminar in Spring Hill, Florida. It had an impact on me. I was compelled to get your books and start reading, something I really don’t like to do. After reading the first chapter in One Heartbeat Away I had to stop and get to sharing. All the questions you asked made me think about how important it is to share our faith and how simple it is to do it by just asking people real questions of them that make them think about eternity. Thank you for a wonderful book, and thank you for being a strong example.”

—B Curtis

“I love the way you put things, simple. This allowed me to give One Heartbeat Away to friends, both saved and those who are searching. I am sometimes so passionate about Christ that I intimidate people. But giving away this book helped me play the supportive role instead of the lead, something God has been working on with me since my conversion. Your book walks them right down the path and handles all the excuses, tangents, and questions. Thanks for planting the seed of the Word of God deep into friends of mine with your book. Now that my friends and I are closing in on 40 and have children who mean so much to us, we need to be able to answer the most important question there is: What happens after this? if for no other reason than to lead our children the right way, His way. Thanks for keeping it simple and on point. We all are one heartbeat away!”

—S Gallagher

“I read through One Heartbeat Away in two days. Those days just happened to be right before our big evangelistic outreach for our youth ministry that we do several times a semester. I was so impressed with the logical progression of truth in it that I used the same approach and info in my message. There were 10 students that made first-time professions of faith! This is an incredible resource for anyone wanting a solid foundation from which to personally share their faith, and it is a great giveaway for the lost.”

—C Walker
Youth Ministry, Lubbock, TX

“One Heartbeat Away is my favorite book to leave a lost person with following a conversation. It not only presents all the information they need to make a calculated decision concerning Jesus Christ and their eternal destination, but I find it usually extends on points I made during the conversation—great edification for non-believers. I gave away three copies to an atheist and two skeptics after a great talk in a McDonald’s parking lot. All three seemed interested in reading it, particularly the atheist. Glory to God!”

—J Hayes
Vice President & Information Director, Project 100 Ministries

“One Heartbeat Away is done very well and does a fantastic job of explaining who we are and what we’re here on earth for. You won’t hear a better explanation of the gospel than this (other than the Bible, of course!). Basically, it’s one giant tract! If only all 6 billion people in the world could read this book! I thank God for you, Mark.”

—B McCurdy, 35
Real Estate Agent, Cottonwood, CA

“Immediately after reading One Heartbeat Away, a powerful sense of urgency to witness has been placed in my spirit. I have a renewed compassion for people’s souls to be saved, and am now willing to carry this burden for their salvation.”

—Homer, AK

“This resource, One Heartbeat Away, can reach a broader range of people than almost any I’ve come across: young, old, kind, or cruel. Solid truth presented in a challenging, readable form. We truly believe this book helps patients leave our office with their spiritual eyes open. We’ll soon be ready for 1,500 more.”

—S Kirkham, MD

“Since reading your book, One Heartbeat Away, I have had a burning inside that won’t let me be still. I feel an urgency to share the gospel. It has given me even more of an eternal perspective than I had before. I’ve given several of the books away. I am constantly in prayer and looking for opportunities to share with someone.”

—K McDonald, 35

“I wish I could hand out One Heartbeat Away as a tract by the hundreds. The information in the first three chapters is an excellent tool for the Christian to use while witnessing. Thank you.”

—S Lester, 29
Broiler Service Technician

“One Heartbeat Away is a great book that gave me more confidence when dealing with my more skeptic friends. We all have friends that, regardless of the change in our lives and the strength of our own testimony, just can’t grasp the concept of a loving, all-powerful God. Just after reading the book, I had lunch with an old friend who I’ve been praying for 10 years. With a new-found zeal and confidence, we again talked about Christ. Using examples from One Heartbeat Away, we had a great conversation, and he even agreed to read the book with an open mind! You have to know my friend to realize the magnitude of this commitment. Thanks Mark, for taking the time to research and write such a powerful tool to help win the world for Christ.”

—J Creed, 56

“I read your first book last summer and shared it with some of my close friends. It radically changed us forever. So when the new book One Heartbeat Away came out, we jumped on it. It is at least as awesome as the first. Great work, Mark. Thanks for your time, effort, boldness, sharing with the lost, and equipping the saints.”

—Michael M, 17 years old

“Thanks so much for the book One Heartbeat Away. I believed in God but could not really tell anyone why I believed. Your book answered a lot of questions that I had. Now, I can’t wait to share my faith with everyone. In fact, I just ordered more of your books to share with family and friends.”

—L Christman, 30

“Now that my fiance has read One Heartbeat Away, which he loves, we’ve been talking about how, before we get married, we really need to make God a focal point in our relationship. We both know He has given us the other and made our relationship work through some really difficult times (He’s at West Point and will be deployed in the near future). Now, I want to read this book and give it to my family. I want to see what my fiance is excited about. I think it’ll give us a great starting place in making God the focal point of our relationship.”

—M Bartholomew

“I just finished reading your new book One Heartbeat Away: keep the presses running! This book is a must to have ready to give a person who is searching for the most important answer to Where will you be after you leave this planet? I was talking to a client the other day, and during the conversation, I asked him how things were going. He said, “Going? I died over the weekend!’ I said, “What do you mean?’ He said he had a heart attack and flat lined. He knew he had died, but they brought him back. I asked him, “Do you think God may have been giving you another chance?’ “Yes!’ he replied. I told my client that I was just finishing a book called One Heartbeat Away and considering what happened to him over the last weekend, I wanted to mail him a copy of the book. He said “Okay!'”

“I have severe dyslexia, which makes reading a real drag, but when I picked up your book One Heartbeat Away, it was not only understandable, but powerful and fun to consume.”

“The book you gave me, One Heartbeat Away, I have read cover to cover in the last 7 hours, only stopping to eat dinner, check in at the hotel, and tell my fiance about it.”
