This powerful realm is ruled by Beelzebub, “the ruler of the demons” (Luke 11:15), whom Jesus calls Satan. When Jesus drives out the demons, he takes on the enemy of humankind. The ruler of the demons proves powerless against Jesus and the kingdom of God. Once a person has been freed of the invader spirit and liberated from Satan’s oppression, Satan is defeated, at least temporally, and the person is free once again to receive the blessings of the kingdom of God.
