Matthew 7:15-18
A Tree and Its Fruit
7:15 “Watch out for false prophets, who come to you in sheep’s clothing but inwardly are voracious wolves.
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.
