Matthew 12:28-34

But if I cast out demons by the Spirit of God, surely the kingdom of God has come upon you. Or how can one enter a strong man’s house and plunder his goods, unless he first binds the strong man? And then he will plunder his house. He who is not with Me is against Me, and he who does not gather with Me scatters abroad. “Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come. “Either make the tree good and its fruit good, or else make the tree bad and its fruit bad; for a tree is known by its fruit. Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks.
