Deliverance ministry of Jesus Christ on how it differs from the Jewish and Greek Exorcist of His Day He did not use a magical formula to cast out demons. He simply cast out demons by the authority of the Spirit of God, in which He magnified the Kingdom of God, and disarmed the Kingdom of Darkness.
Jesus Christ gave his 12 disciples and 70 disciples authority over devils, just as He has given the believer today authority over demon spirits.
