Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is recognized by its fruit. You brood of vipers, how can you who are evil say anything good? For out of the overflow of the heart the mouth speaks. Good people bring good things out of the good stored up in them, and evil people bring evil things out of the evil stored up in them. But I tell you that people will have to give account on the day of judgment for every empty word they have spoken. For by your words you will be acquitted, and by your words you will be condemned. Matthew 12:33-37
