Fruits

Matthew 7:
15"Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves.  16You will know them by their fruits. Are grapes gathered from thorns, or figs from thistles? 17So, every sound tree bears good fruit, but the bad tree bears evil fruit.  18A sound tree cannot bear evil fruit, nor can a bad tree bear good fruit.  19Every tree that does not bear good fruit is cut down and thrown into the fire.  20Thus you will know them by their fruits.
