Matthew 12:34-37

You brood of vipers, how can you speak good things when you are evil? For the mouth speaks out of that which fills the heart. The good man, from his [inner]good treasure, brings out good things; and the evil man, from his [inner]evil treasure, brings out evil things. But I tell you, on the day of judgment people will have to give an accounting for every careless or useless word they speak. For by your words [reflecting your spiritual condition] you will be justified and acquitted of the guilt of sin; and by your words [rejecting Me] you will be condemned and sentenced.”
