(Matt. 7:19-20) "Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them."
This has to do with false prophets. (Matt. 7:15) "Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves."
So, you shall know the false prophet or teacher by the fruit he produces. But, there is a problem. The false prophet/teacher comes in sheeps clothing. If he came as morally degenerate with his outward sins being seen by all, he is easily exposed. But he doesn't. He comes as a sheep. He comes in goodness, and sincerity, and nothing immoral will be seen in him.
So, how can you recognize him by his fruit? The fruit is going to be that which is produced by the Spirit of God in a true prophet or teacher. The false prophet/teacher is tapped into another spirit, and his fruit is not of God. If you set up a man teaching a Bible class who is a believer and one God has called to teach, when he teaches the Holy Ghost will minister to those listening, and they will recognize it But if a non-beiever, posing as a believer starts a Bible class, it will be empty of the Spirit. Nothing there. The believers who came will go away empty and their spirit parched.
Then next week, guess which Bible class has more members, and which one has fewer. As (Matt. 7:16) says, "Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?" Do you go to the thorn vine to get grapes? No, you go to where there are grapes.
(John 10:1-5)
