Spiritual Warfare - Exorcisms You've probably seen the programs (or at least excerpts from them) on television featuring a man casting out demons from people. The most well known of these exorcists is Bob Larson. Larson, Bible,crucifix, and microphone in hand, will go up to the allegedly demon possessed individual and interview the hellish creature which will obligingly speak through the otherwise normal looking person. The demon will hiss and growl and protest and even make its victim twist and contort but, eventually, the nymph will obey Larson and vacate its hapless human host for, presumably, one not attending a Bob Larson conference. So, are exorcisms real? Do we have the authority that Christ and His Apostles had to cast out demons? Jim Osman, author of Truth or Territory: A Biblical Approach to Spiritual Warfare gives us the biblical truth.
