In this book, well-known evangelist Bill Subritzky describes how people can be released from demonic oppression. In more than thirty years of ministry he has seen God set free thousands of Christians, including ministers and church leaders. Demons Defeated has become a classic handbook on deliverance and this fifth edition has been updated.

The author faces the question of whether a Christian can have a demon, examines various methods of deliverance, and teaches how deliverance can be maintained. He exposes the dangers of involvement with the occult, cults and non-Christian religions. The book also includes prayers for deliverance, release from curses, soul ties and Freemasonry.
