“Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.
This verse (and the following few verses) follows directly after where Jesus spoke on entering by the narrow gate and walking along the narrow way (v. 13-14). Hence, what Jesus is suggesting here is that we beware of those who will try to persuade us not to enter at the narrow gate and walk in the narrow way. These are false prophets.
We will now take a closer look at these false prophets, according to what D. Martyn Lloyd Jones has preached on in his Studies in the Sermon on the Mount. In my reading and note taking, I have come up with ten descriptions of the false prophet.
1. They will appear as Christians. They will come to us in sheep’s clothing, but inwardly they will be ravenous wolves. Therefore, they will look like good people and no one will suspect anything false from them. They will be nice and pleasant and appear to be Christians. They will use Christian terms and talk about God, and Jesus, and about the cross, and about the love of God, etc.
2. We will know them by their fruit. When we really get to know them, we will discover that their teaching is wrong and also their life (their conduct).
3. We may recognize them by what they do not teach. As far as recognizing the falseness, it is not so much recognized by what they say, but rather by what they do not say. They will tend to leave out or pass over certain important biblical teachings. And they do this in order to not offend you or to be more popular.
4. His teaching is absent from doctrine. His preaching is almost entirely absent from doctrine. He does not like doctrinal preaching, and when he does preach doctrine, it is vague and in error.
5. He does not speak on holiness. The false prophet rarely speaks about holiness and righteousness and justice and the wrath of God. He will not say that he does not believe these things, yet he says next to nothing about them.
6. He leaves out bible prophecy. The false prophet fails to talk about bible prophecy and future things. This is true of most preachers these days. But I have a remedy for them. If they would just preach through the bible one verse at a time, they would be forced to preach on bible prophecy, since almost one-third of the bible is prophetical.
7. He fails to preach on sin. He will not emphasis the doctrine of sin and the sinfulness of sin.
8. He will not preach on what Jesus did for us on the cross. He will talk about the cross and about the death of Christ, but he will fail to preach on what Jesus’ death did for us—that God made Him to be sin for us (2 Cor. 5:21) and that He paid the penalty for our sins.
9. He dislikes self-examination. He will not emphasize the necessity of entering the narrow gate or walking in the narrow way. He is not interested in true holiness; thus, he dislikes the process of self-examination and the mortification of sin as taught by the Puritans.
10. They reject the idea of being a Christian warrior. They reject talk about fighting the good fight of faith, and they do not see the need for putting on the armor of God. They would rather practice easy salvation and living an easy and prosperous Christian life.
