Matthew 12:31-37 English Standard Version (ESV)

³¹ Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven. ³² And 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.

A Tree Is Known by Its Fruit

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. ³⁴ You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks. ³⁵ The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil. ³⁶ I tell you, on the day of judgment people will give account for every careless word they speak, ³⁷ for by your words you will be justified, and by your words you will be condemned.”
