Discover the Book Ministries

DTBM is a partnership of people from everywhere John Barnett has ministered (SC, CA, NY, MI, RI, OK, etc.) who help spread God's Word through taking the lessons already taught to a local church and making them available free of charge all over the USA and the World.

John Barnett founded DTBM in 1998, as a non-profit 501c3 Oklahoma incorporated, outreach ministry. Currently DTBM is sending evangelistic and Bible teaching materials (books, study guides, CDs, radio shows, web based materials, etc) to over 160 countries around the world. The main offices are in Tulsa but there are other locations we support for translation work (in Russia, Jordan, Brazil, Korea, etc.) and to produce daily broadcasts.


Dr. John Barnett

Dr. John Barnett has been teaching the Word of God for 30+ years. Born and raised in Michigan, John has studied at Michigan State University, Bob Jones University (B.S., B.A., M.A., M. Div.), The Master's Seminary (faculty and Th. M. work), Dallas Theological Seminary (Dr. of Biblical Ministry) and with Francis Schaeffer at L'Abri Fellowship.


John shares his life with Bonnie his beloved wife, and their eight wonderful children. As a home educating family, John and Bonnie teach children and teens with enthusiasm and love. In the past 30 years of uninterrupted ministry, John has served congregations in Michigan, Georgia, Rhode Island, California and Oklahoma before coming to the precious saints at Calvary Bible Church in Kalamazoo, Michigan in 2008. He has served on the Faculty of the Master’s College & Seminary. He was an Associate Pastor to Dr. John MacArthur at Grace Community Church for five years overseeing the Shepherding Ministries. During graduate school, John served as the Assistant Dean of Men at Bob Jones University for five years.

Called to the ministry as a young man—his passion remains prayer and the ministry of God's Word. As a global Christian, and having ministered the Word in 40 nations around the world, John's ministry is deeply touched by outreach and evangelism. Since 1978, in conjunction with Land of the Book Tours John has led dozens of study tours, retreats, travels, and pilgrimages with over 1,500 participants, and taught on site in 21 countries and on five continents. His Tours filmed onsite are available to watch online. 

As a Seminary Professor of Theology, Church History and the English Bible, John's messages reflect the background of the Scripture from the ancient biblical world, the history of the church and the daily life in far corners of the planet. In 1998 a new ministry called Discover the Book Ministry was launched to provide electronic copies of Pastor John's audio, video, and text studies free of charge to pastors, missionaries, and other believers. Since then, this ministry has grown to serve saints in all 50 states and over 145 lands around the world, as well as through daily radio on a growing number of radio stations in the USA, Europe and the Caribbean.
