Matthew 12:31-37

31Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven.

32And 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.

34You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks.

35The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil.

36I tell you, on the day of judgment people will give account for every careless word they speak,

37for by your words you will be justified, and by your words you will be condemned."
