Matthew 12:31-34

12:31 For this reason I tell you, people will be forgiven for every sin and blasphemy, but the blasphemy against the Spirit will not be forgiven. 12:32 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.

Trees and Their Fruit

12:33 “Make 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. 12:34 Offspring of vipers! How are you able to say anything good, since you are evil? For the mouth speaks from what fills the heart.
