Matthew 12:31-33

31 "Therefore I say to you, every sin and blasphemy [every evil, abusive, injurious speaking, or indignity against sacred things] will be forgiven people, but[6] blasphemy against the [Holy] 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 [by attributing the miracles done by Me to Satan] 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 recognized and judged by its fruit.
