What does it mean that false prophets are wolves in sheep's clothing (Matthew 7:15)?

The characteristic of false prophets is that they come in sheep's clothing but in truth are ravening wolves. They pass for believers (and some might even be such) and yet their true intention is only manifested when they have entered among the flock: they are have come to steal and to scatter the sheep (John 10:12). They are able to deceive unwatchful children of God by cunningly transforming themselves into apostles of Christ (2 Cor. 11:13-15).

There follows now a warning about false prophets, which is in very plain connection with that about the different roads which men were taking to reach a common end. This is intensified by the fact that, wherever the true Voice speaks, there will come the false voice after it, its mocking echo; like Jannes and Jambres opposing by imitation, putting on the dress of the sheep, but as a lure, over the evil heart within. The fruit would manifest them, but we must remember that this is not necessarily immoral conduct, in which the sheep's clothing would no longer remain, but rather their doctrines tested by experience, as when men looking for grapes find nothing but at most the mockery of these. Satan; when coming in as an angel of light, does not send out open evil-doers to commend his doctrines, while on the other hand an evil life may dishonor the preacher of substantial truth. But a true and needy soul, testing for itself the fruit of what is spoken, will assuredly find that the truth has its own witness to the heart and conscience, such as nothing but the truth can have. Here, above all, the Lord's words apply, that a good tree cannot bring forth bad fruit.

The warning against false prophets follows. They are to be known not by their fine words but by their fruits. Fruit is the result and crowning expression of life, and it reveals the character of the life that it consummates. The false prophet has a false life, which must reveal itself in false fruit.

What does our Lord mean by fruit? Does He mean downright wickedness? There is no question that immorality and evil deeds are included under the term fruit. Many a false teacher began in teaching error in such a way that the error could hardly be distinguished from the truth, but continuing in error he ended with many of his followers in the flesh. Often behind the most subtle errors the flesh is nourished and an outbreak in gross immorality may follow. Yet, if our Lord meant nothing but evil deeds and wickedness, it would be hard indeed to detect these false ones. Satan is not so blind as to peddle his lies around by wicked people whose lives bear the stamp of immorality and open wickedness. He does it in quite another way. We were often told of people who hold the most abominable doctrines and deny the Deity of our Lord as well as the atonement, "But look at the beautiful lives they live! How meek and lovely they are! How much good they do! Do not their lives prove that their doctrine is right and the fruit show that the tree is not bad?" This outward moral appearance and a "sweet" temper belongs only too often to the sheep's clothing and is one of the devices of Satan with which he tries to lead many away from the truth and into error -- the fruit by which we shall know them may be wickedness in the grossest form, but it means more than that. The word "Do men gather grapes from thorns and figs from thistles?" is the key. Grapes and figs speak of true fruit. Thorns bear fruit which may resemble grapes, but never can they be grapes from which comes the wine which makes glad the heart of God and man. The soul looking deeper (and we remember the warning is for believers) than outward appearances finds soon that the false teacher or spirit is not in the truth. He tests it by the Word, and finds the fruit, the glory of Christ and glorying in Him, lacking. It is a most subtle substitute for the true fruit -- a counterfeit -- and leaves the soul empty. A believer, not much taught in the Scriptures, sent us a few weeks ago a question about a certain publication which was sent to him with the promise of leading him into a better knowledge of the Bible inasmuch as it was devoted to Bible study. We wrote him at once exposing the true character of the paper. He answered, that while he had but little knowledge yet of the Word, and while much seemed to be in favor of the paper which had been placed into his hands, yet while reading he experienced a feeling of emptiness, there was no response from his heart and a lack of joy and peace. This, perhaps, will be helpful to see how a true believer will know them by their fruit.

However, this must be guarded too, for there is a narrowness that is false and evil, a specious counterfeit of what is true. False prophets have abounded throughout history, and because of the wonder of the pure reality of truth revealed in the person of Christ, they have increased in number, for they, see opportunity of greater personal advantage in counterfeiting Christianity. They come in sheep's clothing, pretending to be believers, in some measure acting like it, but inwardly wolves, intent on doing harm.

But the believer may discern them by their fruits. They bear the character of thorns and thistles, harmful rather then productive, not ministering food for the need of souls. No child of God should be deceived by them. They tickle men's ears, usually appealing to the pride of intellect, but ignorant of the truth that reaches consciences and hearts. Grapes and figs are healthy foods, but not available from thorns or thistles.

The fruits are first of all the words of the prophets. True prophets of God also may fail in their manner of life and their deeds. Whereas false prophets are often characterised by an especially amiable nature. This is why the fruits in this case are not only deeds but particularly the teaching which is brought. By them the disciples of Jesus will recognise if the Spirit of God or a false spirit is speaking. The Word of God says: 'Try the spirits whether they are of God; because many false prophets are gone out into the world.' and 'He that abideth in the doctrine of Christ, he hath both the Father and the Son. If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed' (1 John 4:1 and 2 John 9-10).

"But beware of false prophets, which come unto you in sheep's clothing but within are ravening wolves. By their fruits ye shall them recognise. Do they gather from thorns a grape bunch or from thistles figs? So every good tree produceth good fruits, but the worthless tree produceth bad fruits. A good tree cannot produce bad fruits, nor a worthless tree produce good fruits. Every tree that produceth not good fruit is cut down and cast into the fire. Therefore at least by their fruits ye shall recognise them well

Every reader of the O.T. may learn the destructive part by the false prophets who followed like a dark shadow the holy men whom the Holy Spirit inspired, and took up popular cries to oppose the warnings of God as evil became more rampant. There is no less danger now, as Peter particularly insists under the gospel; not to say that there is so much the more when good men pretend not to inspiration and are no longer invested with miraculous vouchers, but press only the word in the Spirit. And so it will be again for the godly remnant in the last days when, the heavenly ones being caught up, it becomes a question of that land and people. But the Lord's warning is of living value now also, as we hear in the worst and deceptive form (1 John 2:18-23; 1 John 4:1-6; 2 John 7-11). What believer does not know of the boldest antagonism to the truth? What Christian has not tasted bitter grief in seeing saints of God deluded by the sheerest clap-trap? Yea, even conniving, for alleged peace, unity, or testimony, at the denial of Christ's Person?

They who love Christ do well to beware of false prophets, who are such as come unto them in the garb of sheep, but within are ravening wolves. They may cultivate sanctimoniousness and pretend to devotion, but are under the dominion of a mightier foe than themselves, and filled with the keenest zeal to deprive the Christian of a true Christ, of life eternal possessed, of present standing as God's righteousness in Christ, of association with Him in and for heavenly glory. Are not such truly ravening wolves? What remains, if the disciple lose all the treasure distinctive of Christianity?

"By their fruits ye shall recognise them." Do they exalt Him who humbled Himself? Do they confess His incomprehensible being, God and man in one Person? Do they proclaim His grace and truth? Do they follow Christ in absolute subjection to scripture? Do they own it, as the invaluable standard, and the sure communication, of God's mind by His Spirit? Is the believer established? Is the sinner won and delivered? Or are minds filled with ideas which but inflate the spirit, inspire self-complacency, and end in death? For these are practical effects which test what men teach, and which are legible enough to simple souls little versed in scriptural truth, and still less in human subtleties. And thus the Lord safeguards the sheep in various ways.

In His closing words our Lord gives a most solemn warning against false prophets, and makes a contrast between the false professor and the true possessor. "Beware of false prophets, such as come to you in sheep's clothing, but within are ravening wolves!" (verse 15). Let us notice first of all that this warning has a special significance for the closing of the age, that is, the ending of this dispensation, the seven years of tribulation and sorrow in the earth. We only need to turn to the Olivet discourse (Matt. 24) in which our Lord answers the question of His disciples concerning the consummation of the age. When they asked about this ending of the age they surely meant nothing else but the Jewish age, for of a Christian age they knew nothing. In answer our Lord gives, describing the events which fall into the seventieth week of Daniel, He says: "And many false prophets shall arise." These false prophets will make their appearance during the great tribulation, no doubt under the leadership of the false prophet, the Beast, so prominent in the book of Revelation. That there have been throughout this dispensation false prophets in sheep's clothing and that they are more numerous now than they have ever been before we need hardly mention, yet strictly speaking, the warning against false prophets concerns the Jewish remnant in the earth during the time of Jacob's trouble. Nowhere are we as believers warned against false prophets; we are warned against false spirits and false teachers, which of course, like the false prophets come in sheep's clothing. False prophets then, after the church is taken, to lead many astray; false teachers and false spirits now while the Church is still on the earth. The false prophets, who will undoubtedly work many miracles and be leaders of the strong delusions, are the visible manifestation of the false spirits which are now at work. When Paul said farewell to the Elders of Ephesus he said: "For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them" (Acts 20:29, 30). How soon this prophecy was fulfilled! Let us remind ourselves of some of the solemn warnings which are for the Church. "Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world and not after Christ" (Col. 2:8). "O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings and oppositions of science, falsely so-called, which some professing have erred concerning the faith" (1 Tim. 6:20). The very errors and false teachings so prevalent in these days are marked out here. "Now the Spirit speaketh expressly that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of demons" (1 Tim. 4:1). And how great the increase of these seducing spirits in our day! "But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord who bought them, and bring upon themselves swift destruction" (2 Pet. 2:1). The so-called "Higher Critics," who sit in wicked judgment upon the infallible Word of God and dishonor Christ, the living Word, are meant here. And where are these men not found throughout Christendom? See also the warnings against false spirits in the first Epistle of John. (1 John 4:1-3; 2 Cor. 2:17; 2 Cor. 11:13-15; Titus 1:10, 11, and other passages).

But whether they are false prophets coming in the future or the false spirits and teachers at the present time, they come in sheep's clothing. Anti-Christ himself will first speak like a lamb and have a flattering tongue, and all the prophets under his control will follow him, backing their assertions by signs and lying miracles. The story of Moses and Aaron sent by Jehovah, and Jannes and Jambres sent by Satan and endued by him with power, will then be acted out again (Exodus 7:11). In this way many will be led astray. In our age Satan transforms himself into an angel of light, and the false spirits and teachers appear like meek sheep of the Great Shepherd. In the subtle infidelity which denies the inspiration of the Bible, Satan has surely transformed himself thus. There is much talk from their side of "Bible research," and that their work will help in bringing out the truth, and many declarations that they are sincere and earnest Christian workers in spite of their infidelity in the divinity of the Scriptures, but all this is but the sheep's dress in which they make their appearance. We think of other false teachers who deny the eternal Deity of our Lord, the physical resurrection of Him and the revealed facts concerning the dead in Christ and those who died unsaved. (We have reference to the "Millennial Dawn Series." Thousands have been led astray by these books which appear indeed in sheep's clothing, but within is the ravening wolf who wishes to harm the flock of Christ.) All these soul destroying false teachings come in the garb of truth and light.

There is another kind of false prophecy which can ensnare the hearts of believers. Sometimes men arise who speak about so-called hidden sins or entanglements of believers and bring real or supposed sins to light. By doing this they appeal to the feelings of many believers and seek to influence them. Often they not only say false things but some true things as well. And so many hardly recognise that they are false prophets.

The Lord Jesus says: 'Beware of false prophets.' The best way to discern the false from the true in spiritual matters is not to know the false but to know the true. The believer does not need to be able to refute every false doctrine, but should turn away as soon as he recognises that there is something that does not glorify his lord and Redeemer. And to recognise a false prophet one must know the features of a true prophet. A true prophet speaks out of communion with God to the hearts and consciences of his listeners. He will lead them into the light of God, to a deeper knowledge of Him and closer fellowship with Him. A prophetic ministry is characterised by ministering 'oracles of God' (1 Pet. 4:11), by reaching the hearts and consciences of the listeners and by working edification, exhortation and comfort or encouragement (1 Cor. 14:3).

(1 John 4:1-6). Before proceeding with this great theme, the Apostle, in a parenthetical passage, warns us against false spirits. Such are in the world, and it is necessary to warn believers against them. We are warned of the necessity of proving the spirits by which men speak, and to beware of estimating people merely by their profession. Many who profess to be the prophets of God are in reality false prophets speaking by evil spirits. From the Lord's own words we know that a false prophet is one who has every appearance of being one of His sheep, for he comes in sheep's clothing, but inwardly he is but a ravening wolf bent on the destruction of the sheep (Matthew 7:15).
