Eternity is rushing towards us.
You and everyone else must be ready.


God has blessed this ministry with people who feel led to donate to help continue His ministry work of reaching all people with the gospel of Christ. All financial support goes exclusively to the work of God and has literally kept me going to reach the lost. Your donations are gratefully appreciated and used, among other things, for the expenses of the ministry and the development of new teaching tools.

    Prayer Support

    After I spoke at a conference, a creation scientist came up and told me, “I have listened to you speak twice and really feel led to pray for you every day. You are on the front lines doing exactly what Satan doesn’t want us to be doing. You are either witnessing or equipping others to witness, so I need to pray for you.” I told him that I would very gratefully accept those prayers.

    Prayer is necessary for the furtherance of this ministry. I want everything I do for the Lord to be His will and not my will. If you feel led by the Lord to pray for me one day a week, please send me a note to let me know that you are doing so. Thank you so much for partnering with me in this way.

    We are grateful for all your prayer and financial support that equips Mark Cahill Ministries to further the work of the Lord!

    Keep reaching the lost! Thank you!
