And the scribes who came down from Jerusalem were saying, “He is possessed by Beelzebul,” and “by the prince of demons he casts out the demons.” And he called them to him and said to them in parables, “How can Satan cast out Satan? If a kingdom is divided against itself, that kingdom cannot stand. And if a house is divided against itself, that house will not be able to stand. And if Satan has risen up against himself and is divided, he cannot stand, but is coming to an end. But no one can enter a strong man’s house and plunder his goods, unless he first binds the strong man. Then indeed he may plunder his house.
(Mark 3:22-27 ESV)
The Pharisees are back again! And this time they accuse that Jesus is possessed by Beelzebul and also that Jesus is using the power of demon prince to cast out demons. Jesus rebuked them saying that it’s not logical, how can someone use the power of satan to cast out satan?
If satan starts attacking satan themselves, they soon will be destroying themselves. Instead Jesus claim that he’s the plunderer, he has come to plunder satan, he is the one who can bind the strong man.
