69. Where Do Wicked Words Come From? – And Answer Concerning Idle Words. Mt. 12:33–37

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. You brood of vipers! How can you speak good things when you are evil? For out of the abundance of the heart the mouth speaks. A good person brings good things out of a good treasure, while an evil person brings evil things out of an evil treasure.

I tell you that on the day of judgment people will give an account for every careless word they have spoken. For by your words you will be justified, and by your words you will be condemned.
