Mark Bubeck founded the International Center for Biblical Counseling in 1986 while serving as pastor of the Central Baptist Church in Sioux City, IA. In 2006, ICBC became Deeper Walk International and has been a beacon for a biblically-balanced approach to spiritual warfare ministry ever since. Mark was promoted to glory on November 6, 2017, but the principles on which he has built his life remain foundational to our ministry.

He authored a number of notable books including The Adversary, The Adversary at Home, Overcoming the Adversary, Fire from Heaven, and Warfare Praying. According to his daughter, Judy Dunagan, Mark “Lived all that he taught, and he was the most Christ-like person I have ever known.”
