Matthew 7:15-20 NKJV
“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.
