Matthew 12:28-34

But if it is by the Spirit of God that I cast out the demons, then the kingdom of God has come upon you [before you expected it]. Or how can anyone go into a strong man’s house and steal his property unless he first overpowers and ties up the strong man? Then he will ransack and rob his house. [Is 49:24, 25; Mark 3:27] He who is not with Me [once and for all on My side] is against Me; and he who does not [unequivocally] gather with Me scatters. [Luke 9:50; 11:23] “Therefore I say to you, every sin and blasphemy [every evil, abusive, injurious speaking, or indignity against sacred things] will be forgiven people, but blasphemy against the [Holy]Spirit will not be forgiven. Whoever speaks a word against the Son of Man will be forgiven; but whoever speaks against the Holy Spirit [by attributing the miracles done by Me to Satan] will not be forgiven, either in this age or in the age to come. [Mark 3:29; Luke 12:10] “Either make the tree good and its fruit good, or make the tree bad and its fruit bad; for the tree is recognized and judged by its fruit. You brood of vipers, how can you speak good things when you are evil? For the mouth speaks out of that which fills the heart.
