Demonic Possessions, Exorcisms, and Sanctification Can a Christian be demon possessed? Can a lost person be demon possessed? There are so called "deliverance ministries" out there which purport to be able to exorcise demons out of people and thereby deliver them from depression, anger issues, various addictions and on and on. Bob Larson, for example, is well known for his dramatic and theatrical expulsions of Satan's minions. Is this stuff real? Demons themselves are real, of course, but what power do they have? What power do we have over them? What hindrance could demons potentially pose to the sanctification of the believer? Jim Osman, author of Truth or Territory, walks us through these issues.
