Matthew 12:24-34

24 But when the Pharisees heard it, they said, "It is only by Beelzebul, the ruler of the demons, that this fellow casts out the demons."
25 He knew what they were thinking and said to them, "Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand.
26 If Satan casts out Satan, he is divided against himself; how then will his kingdom stand?
27 If I cast out demons by Beelzebul, by whom do your own exorcists cast them out? Therefore they will be your judges.
28 But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come to you.
29 Or how can one enter a strong man's house and plunder his property, without first tying up the strong man? Then indeed the house can be plundered.
30 Whoever is not with me is against me, and whoever does not gather with me scatters.
31 Therefore I tell you, people will be forgiven for every sin and blasphemy, but blasphemy against the Spirit will not be forgiven.
32 Whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
33 "Either make the tree good, and its fruit good; or make the tree bad, and its fruit bad; for the tree is known by its fruit.
34 You brood of vipers! How can you speak good things, when you are evil? For out of the abundance of the heart the mouth speaks.
