H. A. Maxwell Whyte (1908–1988) embarked on a journey in ministry that was fraught with uncertainty and an absence of familiar landmarks when he was sovereignly led by the Holy Spirit into an understanding of demonic activity and spiritual warfare. As is often the case with pioneers, he was misunderstood, ridiculed, and ostracized by the Christian community, even in his own city of Toronto. Despite great opposition, he forged ahead in the battle against the forces of Satan, convinced that the ministry of deliverance was scripturally based and was being restored to the church in his day. Later, he began to record his experiences, and over the next two and a half decades, he authored eighteen books. His first book, The Power of the Blood, has been translated into several languages and is widely distributed throughout the world, selling over half a million copies internationally.
