A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. Matthew 12:35

“You brood of vipers, how can you who are evil say anything good? For the mouth speaks what the heart is full of. The good man brings good things out of his good store of treasure, and the evil man brings evil things out of his evil store of treasure. But I say unto you, that every idle word that men shall speak, they shall give account thereof in the day of judgment.”
