Matt 12:34-37
34 "You have minds like a snake pit! How do you suppose what you say is worth anything when you are so foul-minded? It's your heart, not the dictionary, that gives meaning to your words. 35 A good person produces good deeds and words season after season. An evil person is a blight on the orchard. 36 Let me tell you something: Every one of these careless words is going to come back to haunt you. There will be a time of Reckoning. Words are powerful; take them seriously. 37 Words can be your salvation. Words can also be your damnation."
