Matthew 12:27

But when the Pharisees heard it, they said, “This man does not cast out demons except by Beelzebul, the prince of the demons.”

Knowing their thoughts, Jesus said to them, “Every kingdom divided against itself is brought to desolation, and every city or house divided against itself will not stand.

If Satan casts out Satan, he is divided against himself. How then will his kingdom stand?

But if I by the Spirit of God cast out demons, then God’s Kingdom has come upon you.

Or how can one enter into the house of the strong man and plunder his goods, unless he first bind the strong man? Then he will plunder his house.

“He who is not with me is against me, and he who doesn’t gather with me, scatters.
