"Dean Sherman is dean of the College of Christian Ministries at Youth With A Mission's University of the Nations. He is respected internationally as a Bible teacher, having taught on spiritual warfare and relationships since the 1970s in ministers' conferences, YWAM schools, and churches in 49 states and more than 40 countries. God has called Christians to overcome the world and drive back the forces of evil and darkness at work within it. Spiritual warfare isn't just casting out demons; it's Spirit-controlled thinking and attitudes. Dean Sherman delivers a no-nonsense, both-feet-planted-on-the-ground biblical approach to the unseen world. Over 300,000 copies sold
