31Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven.
32Whoever 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 one to come.
33Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad; for a tree is known by its fruit.
34You brood of vipers, how can you who are evil say anything good? For out of the overflow of the heart, the mouth speaks.
— Matthew 12:31-34
