A Tree Is Known by Its Fruit

15 Be on the watch for false prophets, who come to you in sheep's clothing, but inside they are cruel wolves. 16 By their fruits you will get knowledge of them. Do men get grapes from thorns or figs from thistles?

Matthew Henry's Commentary on Matthew 7:15-16

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.
