Matthew 12:31-37

31“So I tell you, every sin and blasphemy can be forgiven—except blasphemy against the Holy Spirit, which will never be forgiven.

32Anyone who speaks against the Son of Man can be forgiven, but anyone who speaks against the Holy Spirit will never be forgiven, either in this world or in the world to come.

33“A tree is identified by its fruit. If a tree is good, its fruit will be good. If a tree is bad, its fruit will be bad.

34You brood of snakes! How could evil men like you speak what is good and right? For whatever is in your heart determines what you say.

35A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart.

36And I tell you this, you must give an account on judgment day for every idle word you speak.

37The words you say will either acquit you or condemn you.”
