15 "Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. 16 You will know them by their fruits. Are grapes gathered from thorns, or figs from thistles? 17 So, every sound tree bears good fruit, but the bad tree bears evil fruit. 18 A sound tree cannot bear evil fruit, nor can a bad tree bear good fruit.
Matthew Henry's Commentary on Matthew 7:15-18
Commentary on Matthew 7:15-20
(Read Matthew 7:15-20)
Nothing so much prevents men from entering the strait gate, and becoming true followers of Christ, as the carnal, soothing, flattering doctrines of those who oppose the truth. They may be known by the drift and effects of their doctrines. Some part of their temper and conduct is contrary to the mind of Christ. Those opinions come not from God that lead to sin.
