Dr. Mark I. Bubeck is the founder and president emeritus of ICBC, inc. A pastor for over 40 years, Dr. Bubeck is the author of The Adversary, Overcoming the Adversary, The Rise of Fallen Angels, and Raising Lambs Among Wolves now updated and re-published as The Adversary at Home.

His godly walk and commitment to a biblically balanced approach to spiritual warfare have been used by the Lord to help awaken evangelicals to the need for revival and the reality of the spiritual battle facing the Church today. Mark has "retired" to an active speaking, writing and counseling ministry with ICBC, but the principles on which he has built his life remain foundational to our ministry.
