Matthew 12:30-37

Anyone who is not with me is against me, and anyone who does not gather with me scatters. Therefore, I tell you, people will be forgiven every sin and blasphemy, but the blasphemy against the Spirit will not be forgiven. Whoever speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the one to come. “Either make the tree good and its fruit will be good, or make the tree bad and its fruit will be bad; for a tree is known by its fruit. Brood of vipers! How can you speak good things when you are evil? For the mouth speaks from the overflow of the heart. A good person produces good things from his storeroom of good, and an evil person produces evil things from his storeroom of evil. I tell you that on the day of judgment people will have to account for every careless word they speak. For by your words you will be acquitted, and by your words you will be condemned.”
