“by his word.” For people who have been involved in deliverance ministry, this seems so natural that it can escape our notice. We think, “Of course he cast out demons by his word, how else would he do it?” We have to remember that in the cultures of the biblical world, if there was deliverance from demons at all it usually involved complicated exorcism ceremonies. In stark contrast to those involved ceremonies, all Jesus did was command the demon to go and it left the person.
