The Watchmen for Website Reviews

“This book The Watchmen…. Wow!!!!  Not quite 1/3 of the way in, but dang… it’s a good one.  I can’t say thank you enough my friend.”

— Trampus B.

“Thank you for your inspiration. You are GOD sent. If it weren’t for this book (The Watchmen), I’d still be searching for the meaning of my life’s purpose. Taking on my new journey is going to be challenging, I was just released from jail and I’ve lost everything I had. Im hoping your book will get me through the hard and unexplainable times I will face while taking on this new part of life being legit and sober. Again, thank you!”

— Michaela V.

“I have been reading your book The Watchmen. Powerful, exciting, mindboggling, and missional.”

— Kennedy

“I have been reading your book The Watchmen. Powerful, exciting, mindboggling, and missional.””I think I met you on a plane about 20 years ago! I refer to you as ‘the man on the plane’ and have prayed for you over the years. I was referred to you by friend and after reading your book The Watchmen, I felt it was probably you! Amazing things have been happening. My friend asked me to share my story with you, but I feel you are pretty busy, so I will just say that as we were landing, you asked what you could pray for me. I said I wanted a servant’s heart, so I could serve Him. Took a while, but since it is in God’s time, it will be perfect. May God bless you in your service.”

“I am a Filipino serving here in Bangkok, and I’ve been here for 17 years. Our church is composed of different nationalities but mostly Filipinos. After reading your book The WatchmenI really prayed to God that I would be able to share to strangers, and, indeed, God enabled me and I started sharing, and I was able to bring them to our small group and worship service as well. I wrote to say thank you and to let you know that the book had a great impact in my life.”

“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.

“Hey Chap. The Watchmen  is so inspirational. Personally, i was touched by Mark Cahill. Decisions always have consequences both bad or good. It gave me true facts of what a watchmen truly is, I’m a believer inside and out. I’m spreading the news of the Gospel as much as I can being here with my inmates. I couldn’t put the book down. Totally changed me. Without a doubt, Lord Christ Jesus my Savior. I’m blowing my trumpet to be a watchmen. I’m totally captivated. I already gave this book to another to spread gospel.”

“I just started reading The Watchmen. I am already on page 76! I can’t put it down. I love sharing my faith. The stories and insights are such an encouragement to me. The days are growing darker by the hour.  Jesus’ return is so soon. We must get people to Jesus, and Jesus to people, now more than ever.”

— Kimberly F.

“Thank you for sending The Watchmen to me last year when I ordered some tracts from your website. I finally got around to reading it this past week and have bought many copies to give to my believing brothers and friends. Thank you for writing this book to encourage believers to reach those we know and don’t know with the gospel. I’ve started today by giving a friend your One Second After booklet to read. Thank you for sharing your heart and passion for being a watchman.”

— Jaime

“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.

The Watchmen is probably the best book outside the Bible that I have ever read!”

—Daniel K.

“Thank you for the book you wrote called The Watchmen. I ran across it while I was in prison, and the message is heavy on my heart to warn people of the coming judgment and to be a witness. God bless you, my brother.”

 —TJ  F.

“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!”

 —Vera S.

The Watchmen is now my new favorite. My friend and I have been talking about starting a class that specifically focuses again on evangelism. We continue to love how the Lord is using you to help the church become fearless apostles willing to share the gospel at all cost.”

 —Debra H.

“Your book The Watchmen made me laugh, cry, stand amazed, and repent of my wasted contacts and time! I will hopefully buy a case of these for my workshop ladies! I will even reward them if they read it! It has so many good ideas and convicting heart-twisting reminders!!! Thank you so much for loving our Savior!”


“I bought The Watchmen in a bundle of books having no idea what it was about. I have been absolutely changed by this book. This is the greatest book on witnessing that I have ever read. Thank you, and praise God!”

 —Keever S.

“I have been engrossed by your book The Watchmen. It has been a wake up call to me, once again, for what I have left out for some time. Reading this, again, has been an answer to my prayer for souls. I need more of your books here in Port Harcourt, Nigeria.”

 —Victor O.

“I’m reading The Watchmen for the second time! It is excellent and even better the second time around for folks like me!”

 —Linda B.

“I read The Watchmen, and it set me in motion to share the gospel wherever I go.”

 —Kelly H.

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

 —Yvette C.

“I recently read The Watchmen, and I think the best way to describe it is One Thing You Can’t Do In Heaven on steroids!”

 —Henry A.
Program Director, YMCA

“A couple of months ago, my cousin sent me a copy of The Watchmen. I wanted to let you know how inspiring and motivating this book is. I have had a burning desire to evangelize ever since the Lord saved and transformed me, nearly 23 years ago, but it wasn’t until I read your book that He equipped me for effective street evangelism. It has been a blessing to see the Lord open the eyes of the lost and draw them to Himself. Thank you for equipping the saints for the work of ministry. All for God’s glory.”

 —Jim B.

“Greetings, brother Mark. I am Elisha from Kenya. I bought your book The Watchmen at one dollar on the streets (really don’t know why it was that cheap). I am halfway through, and it’s really stirred something in me to reach out to the lost here in Kenya. I am a young Christian in the faith, but I just have the zeal. I just want God to light up the idle sticks in my heart that I may burn for him.”

Fellow watchman to be,
—Elisha A.

“Greetings from Peru. Our summer volunteer team just finished a chapter-by-chapter study of The Watchmen. I simply love it. By far, your best book yet. Loved the chapter on the Bible, and I think you hit the nail right on the head with regard to false teachings with regard to election and ‘preselection.’ Very nicely done. It was a great supplement to our labor here. I’ve watched these teenagers put the things contained therein into actual practice. I can’t thank you enough for your books. They make for a great team Bible study that is being put into practice all the way down here in Peru. Thank you and God bless, dear brother.”

 —Jesse B., President

“I am a born-again believer but have never been much of a watchman. I send tracts with my bills and leave them at gas pumps, but rarely have I engaged people in one-on-one conversations. Am I ashamed of the gospel? Not at all. Am I very nervous? Absolutely. After reading The Watchmen, I feel that God has finally gotten through to me about the dire urgency and importance of telling people about Jesus, especially my family who are all Roman Catholics. God saved me out of the Catholic church. Thank you so much for your faithfulness in telling people about our Lord. I intend to be a faithful watchman.”


“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 put me on 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!”

 —Reid A.

“I am thankful for The Watchmen because the personal illustrations you give teach about how to have conversations with the lost and your approach helped me to open doors to sharing the gospel while in India. Thanks for your writing ministry. It helped me immensely, and more importantly than that, I believe your writing will be used of the Lord to further His work on this earth.”

 —Dan A.

“Your books are powerful. They stir my passion for the lost. You are indeed touching lives for Christ. I am writing from Ghana.”

 —Joseph B.

“I’ve just finished reading three of your books in the last ten days—One Heartbeat Away, One Thing You Can’t Do In Heaven, and The Watchmen. I’m getting ready to read Ten Questions for The King. I could hardly put any of them down! Your books have totally stepped on my toes, for which I am so grateful. Thank you!”

 —Tyra M.

“I just finished your book The Watchmen, and I really enjoyed it very much. You have such a great way of sharing the gospel. You’re so very eloquent and very easy to understand. I really appreciate your ministry.”


“I read your book The Watchmen, and it has ignited fresh fire of evangelism in me.”

 —Mrs. M.A. A.

“I read your book called The Watchmen and my, my, my, my! What an awesome book to read. You are awesome, and you have really strengthened my faith. I thank you so much!”

 —Lisa S.

“I wanted to give a praise report about the Holy Spirit working through your book The Watchmen. Three years ago my church cleaned out the church library and did some remodeling. A lot of the old books were going to be thrown out, so I went through the discarded books and found The Watchmen.  I thought it was going to be a book about prophecy, but I was wrong when I discovered it was a book about born-again Christians witnessing and spreading the Gospel of our LORD and SAVIOR JESUS CHRIST. I discovered the book on Friday, read the book by Saturday, and was immediately convicted by the HOLY SPIRIT to start witnessing starting on Monday. It’s a great job, and I work for the best Boss in existence!

“I also work as a volunteer for our church’s jail ministry at the local county jail. I push the Christian book cart to the different POD at the jail. I talk to brothers about JESUS CHRIST and suggest different books they might want to read from the book cart. I start the brothers out with One Heartbeat Away, and then as they grow further with the word I give them The Watchmen. I just had a really good praise report from a brother who finished reading The Watchmen.  The brother told me by reading the The Watchmen, it turned his whole life around. He has since joined a prayer group in the POD and reads the Word daily. He also started witnessing the word to fellow brothers in the jail because of his new found conviction. Can’t get any better than seeing brothers in jail coming to JESUS CHRIST.”

 —Stephen B.

“I’m reading The Watchmen for the second time, and what an encouragement it has been to me! God has used your book to open my eyes to be on the lookout for people I can minister to when I go places and at home. I’m more on the shy side, and it’s always felt awkward for me to have even a casual conversation with someone I don’t know. I always wondered if I would ever be able to get out of my comfort zone and be able to share Jesus!  Now, it is becoming more natural to do so! I’ve never contacted someone who wrote a book that I liked or anything, but I felt like God wanted you to know that your life is having an impact on others for His glory. So thank you so much, and keep on serving Him!”

 —Mary Clare M.

“Couldn’t put it down. I am an 83-year-old Baptist gospel preacher. Your book The Watchmen was given to me by my son-in-law who received it from his father. Just returned from the store where I had two divine appointments. I would appreciate your prayers as I continue to be a watchman. Thank you.”

 —Warren G.

“I read your book The Watchmen while ‘in here.’ Let me tell you, I lived a life full of sin. When I got put in here on false charges, I decided to turn to God. The Bible was ‘getting’ to me, but your book was the icing on the cake. My dad was a pastor and told me until the day he died, ‘Kid, you will become a pastor someday.’ I said, ‘Yeah, whatever.’ But now, that is something I am really thinking about. I can’t wait to get out and witness. I have even helped people in here. So I want you to know your book is helping people all over. I also ask you to pray that all goes well for me, and that God has mercy on me so I can start my re-born life right. God bless.”

 —St. Thomas C.

The Watchmen is one of the biggest inspirations and influences on my duty to God and mankind, which is to show them the Way, the Truth, and the Life. I want you to know that I believe those factual encounters with all my heart.”

 —Linda I.

“I could not put this book down because it is so powerful. I thought you must have been African, because as an African who grew up in Nigeria, I was always given very strong writings to read like The Watchmen. Nigerian Christian authors, who have suffered greatly for Christ, write in the same way. In Nigeria, we have to be radical for Christ. I’m thankful that my passion for the Lord is still burning hot, and I’m still radical for Christ.”

“I loved it The Watchmen: direct, challenging, convicting, encouraging, biblical, evangelistic, well-written, great stories. I particularly enjoyed the SPEAK WITH BOLDNESS chapter, as I’m ever seeking creative lines with which to initiate evangelism.”

 —Mike S.

“Ever since reading The Watchmen, my life has not been the same! Although I was already born again, I had a lot of fear and lacked self-confidence whenever opportunities arose for me to preach or even share the gospel in our local fellowship, let alone in church! Now, I can humbly say that I am confident and bold as I continue to open my heart to Christ. I am no longer ashamed of the Gospel of our Lord Jesus Christ.”

 —Marjorie W.

“I just finished your book The Watchmen; and it was, once again, motivational, well-organized, well-researched, and practical, like your other books. I am excited for you to meet your Maker face to face and to see the ripple-effect that your dedication has created in this lost and dying world. May you never lose heart, continue running the race, and keep the faith.”

 —Brett R.

“I greet you in the name of our Lord Jesus Christ. First of all, I thank you very much for the awareness you created in my life through your book The Watchmen. I love every bit of this book. At one point, I felt like I had failed God in evangelism, but this book also made me realize that it is never too late to make amends. I learned many stuffs from your book; how to start a conversation anywhere at any time, how not to do a presentation, how to ask questions, how to bless people with our substance so we can talk to them about Christ, evangelism Bible verses, boldness, and I have also learned your evangelism lifestyle. You have really challenged me and I am grateful. By the way am writing from Ghana – West Africa. God richly bless you.”

“Thank God for the encouragement of Mark Cahill’s ministry! I find it such joy that there is always room to receive God’s mercy and high calling. Thankful for the encouragement of The Watchmen and that it is full of grace and truth!”

 —S Meyer

‘”I love The Watchmen! My friend gave it to me around Christmastime. It has been such a blessing to me. Thank you for letting the LORD use you to write it. God bless you, brother.”

 —J Harrington

The Watchmen is so captivating that you won’t put it down; so compelling that it will cause you to examine your priorities, and so convicting that it will change the way you live your everyday life. A trumpet blast of truth for the Church of Jesus Christ to wake up—a must read!”

 —David F.

“Satan doesn’t like Christians, but he hates Mark Cahill’s guts. Satan can’t fight an army, and The Watchmen is a trumpet call to the army of the Lord, to all who call on the name of Jesus Christ. Awaken!”

 —Jon L.

“The personal illustrations of The Watchmen are the pump-up music I need to keep my gospel trumpet warmed and tuned. Mark’s challenge from Scripture in his newest book, complemented by real personal illustrations of how those Scriptures work in the real world with real people is, for me, everything I need to keep blowing the trumpet of truth with passion. Mark Cahill is a mentor to watchmen.”

 —Don B.

The Watchmen was not written from a back room just based on evangelism theory. Mark has written the most practical, challenge-filled book I’ve ever read written by man on this subject. Anyone with the Spirit indwelling them can tell this was written by a man with constant witnessing experience and a fear of the Lord.”

 —John B.

“If you want what matters most to God to matter most to you, I believe the message in The Watchmen will resonate with you. Tears flood my eyes, as there are no words that can adequately express my gratitude for the faithful watchmen in my life!!!”

 —Linda R.

“This book brings into sharp focus what is closest to God’s heart: that His watchmen live sold-out for Him and warn the lost to take refuge in Christ. Take hold of Mark Cahill’s outstretched hand as his real-life witnessing stories, punctuated by profound truth in The Watchmen pull your heart up on the wall of God to be a resolute and unashamed watchman calling for the perishing to choose life. Incredible encounters and ‘off the charts’ joy awaits those who do!”

 —Brenda N.

“Gave several copies of The Watchmen to friends today. What a powerful message!”

 —Janice C.

The Watchmen is an exciting read. Mark Cahill offers various ways to interact with the public to spread the gospel.”
