Jesus and the Power of Satan in the Gospel of Matthew

The question of how jesus casts out demons is one that occurs on a number of occasions within the gospel of matthew, an important one. It's important to consider how much of jesus ministry is focused upon direct conflict with satan and demonic forces. Jesus seems to acknowledge here that there are others who are performing exorcisms, but his exorcisms seem to be operating on a different level. He is casting out by the spirit of god, which is proof that the kingdom of god has come upon israel. And they aren't even consistent in their accusations, for if they were, they'd be accusing their own disciples and sons who cast out demons.
