Matthew 12:24-28

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

25 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.  26 If Satan casts out Satan, he is divided against himself. How then will his kingdom stand?  27 If I by Beelzebul cast out demons, by whom do your children cast them out? Therefore they will be your judges.  28 But if I by the Spirit of God cast out demons, then the Kingdom of God has come upon you.
