Matthew 12:31-37

31So I can guarantee that people will be forgiven for any sin or cursing. However, cursing 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 in this world or the next.

33“Make a tree good, and then its fruit will be good. Or make a tree rotten, and then its fruit will be rotten. A person can recognize a tree by its fruit.

34You poisonous snakes! How can you evil people say anything good? Your mouth says what comes from inside you.

35Good people do the good things that are in them. But evil people do the evil things that are in them.

36“I can guarantee that on judgment day people will have to give an account of every careless word they say.

37By your words you will be declared innocent, or by your words you will be declared guilty.”
