Matthew 7:16-20

7:16 You will recognize them by their fruit. Grapes are not gathered from thorns or figs from thistles, are they? 7:17 In the same way, every good tree bears good fruit, but the bad tree bears bad fruit. 7:18 A good tree is not able to bear bad fruit, nor a bad tree to bear good fruit. 7:19 Every tree that does not bear good fruit is cut down and thrown into the fire. 7:20 So then, you will recognize them by their fruit.
