Steve Gregg looks at the signs and fruits of false prophets, false teachers, and false elders.
New King James Version (NKJV)
You Will Know Them by Their Fruits15 “Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. 16 You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? 17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore by their fruits you will know them.
2 Peter 2:1-3
2 But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Lord who bought them, and bring on themselves swift destruction. 2 And many will follow their destructive ways, because of whom the way of truth will be blasphemed. 3 By covetousness they will exploit you with deceptive words; for a long time their judgment has not been idle, and their destruction does not slumber.
2 Corinthians 11:12-15
12 But what I do, I will also continue to do, that I may cut off the opportunity from those who desire an opportunity to be regarded just as we are in the things of which they boast. 13 For such are false apostles, deceitful workers, transforming themselves into apostles of Christ. 14 And no wonder! For Satan himself transforms himself into an angel of light. 15 Therefore it is no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works.
A Tree Known by Its Fruit33 “Either make the tree good and its fruit good, or else make the tree bad and its fruit bad; for a tree is known by its fruit. 34 Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. 35 A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things. 36 But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. 37 For by your words you will be justified, and by your words you will be condemned.”
Punishment of Apostates
13 “If there arises among you a prophet or a dreamer of dreams, and he gives you a sign or a wonder, 2 and the sign or the wonder comes to pass, of which he spoke to you, saying, ‘Let us go after other gods’—which you have not known—‘and let us serve them,’ 3 you shall not listen to the words of that prophet or that dreamer of dreams, for the Lord your God is testing you to know whether you love the Lord your God with all your heart and with all your soul.
