Luke 11:22

22 But someone may come who is stronger than he is. That man will attack him and beat him. The strong man believed his weapons would keep him safe. But the stronger man will take his weapons away. He will take the strong man's things and give them to other people.

11:22The strong person is the Devil. The stronger person that comes is Jesus. He fights the Devil and he beats him. When he commands bad spirits to leave people, they do. This shows that he is stronger than the Devil. So it was wrong to think that the Devil was helping him.
