and surrender to the will of God. The path of self-indulgence "leadeth to destruction," by a law which cannot be annulled or set aside. But the path of self-restraint and self-surrender (for these are what make of us men, and not "blind mouths," as Milton expressively puts it), the path which is entered by the strait gate, and is continued along the narrow way, is one which in the course of natural development "leadeth unto life."
The call to enter is followed by words of solemn warning against certain dangers which might beset even those who wish to enter. First, the danger of false guidance: "Beware of false prophets." The danger lies in the future. Hitherto, while speaking throughout of present duty, there have been backward glances over the past, as our Lord has made it evident, point after point, that the righteousness of His kingdom was not the destruction but the fulfilment of the law and the prophets. Now, however, He anticipates the time when there will be those claiming to speak in the name of God, or in His own name, whose doctrines will not be a fulfilment but a destruction of the Truth, and a constant danger to those who may be exposed to their wolf-like ravages. There is manifestly no reference to such differences of opinion as divide real Christians from each other in these days. The doctrine throughout this manifesto is not speculative, but practical; it nowhere brings into prominence matters of opinion, or what are called theological tenets, but everywhere lays stress on that which immediately and powerfully affects the life. So it is here also, as is evident from the criterion suggested for the detection of false teachers: "By their fruits ye shall know them." Besides, the connection in which the caution occurs makes it evident that our Lord had specially in view those teachers who would lead their disciples astray as to the way of life, especially those who would dare to make that easy which he had shown to be "strait," who would set before their hearers or readers a broad path instead of the narrow one which alone leadeth unto life. This is a danger which besets us in these days. There is so strong a sentiment abroad in favour of liberality – and liberality properly so called is so admirable, and has been so much a stranger in times past – that we are in danger of accepting in its name easy-going representations of the Christian life which amount to a total abolition of the strait gate and the narrow way. Let us by all means be liberal enough to acknowledge all who have entered by the strait gate of genuine repentance, and are walking in the narrow way of faith and obedience, however much they may differ from us in matters of opinion, forms of worship, or modes of work; but let us beware how we give even the smallest encouragement to any on the broad road to imagine that they can continue as they are, and find it all right in the end. So to tamper with truth in the guise of liberality is to play the wolf in sheep's clothing.
The test our Lord gives for "discerning the spirits" is one which requires time for its application, but it is the only sure one; and when we remember that the Master is now looking forward into the future history of His kingdom, we can see why He should lay stress on a test whose operation, though slow, was sure. It is of course assumed that the first criterion is the Word of the Lord Himself. This is the law of the kingdom; but, knowing well what was in man, the Lord could not but foresee that there would be those who could so twist any words that might be spoken on those great subjects as to lay snares for the unwary; and therefore, besides the obvious appeal "to the law and to the testimony," He supplied a practical test which, though less speedy in its application, was perfectly sure in its results.
The announcement of so important a test leads to the development of the general principle on which its validity depends – viz., the vital connection between essential doctrine and life. In the long run the one is always the outcome of the other. In the spiritual as in the natural world every species brings forth fruit "after its kind." "Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit." The law being so absolute, making it certain, on the one hand, that where there is truth in the inward parts there will be good fruit in the outward life, and on the other, that where there is corrupt fruit in the outward life there must be that which is corrupt in the hidden man of the heart, it follows that the criterion is so sure as to be without appeal: "Every tree that bringeth not forth good fruit is hewn down, and cast into the fire" (ver. 19), and therefore may well determine the question as to who are trustworthy teachers in the Church: "Wherefore by their fruits ye shall know them."
In the development of the principle the Master's thought has been enlarged so as to include not teachers only, but all His disciples; and His range of view has been extended so as to embrace the last things. The great day of Judgment is before him. He sees the multitudes gathered around the throne. He foresees that there will be many on that great day who will discover, when it is too late, that they have allowed themselves to be deceived, that they have not been careful enough to test their spiritual guides, that they have not been careful enough to try themselves and make sure that their fruits were such that the Lord of the vineyard could recognise them as His own. He is filled with sympathy and sorrow at the prospect; so He lifts up His voice in earnest warning, that, if possible, none of those to whom the words will ever come may allow themselves to fall into so fatal an error: "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of My Father which is in heaven."
How naturally, and as it were unconsciously and inevitably, He has passed from the Teacher to the Judge! Not as a personal claim. In His earliest teaching He kept personal claims as much in the background as possible. But now it is impossible to avoid some disclosure of His divine authority. He must speak of the Judgment; and He cannot speak of it without making it appear that He is Judge. The force of this is all the greater that He is, as it were, surprised into it; for He is evidently not thinking of Himself at all, but only of those who then were or would afterwards be in danger of making a most fatal mistake, leading to consequences awful and irreparable. We can well imagine that from this point on to the end there must have been a light on His face, a fire in His eye, a solemnity in His tone, a grandeur in His very attitude, which struck the multitude with amazement, especially at the authority (ver. 29) with which He spoke: "Many will say to Me in that day, Lord, Lord, did we not prophesy by Thy name, and by Thy name cast out devils, and by Thy name do many mighty works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity" (R.V.).
Again, observe the form the warning takes, revealing the consciousness that to depart from Him was doom– one of the many tokens throughout this discourse that none else than the Lord of life and glory could possibly have spoken it. Yet how many vainly think that they can accept it without acknowledging Him!
The same solemn and regal tone is kept up throughout the impressive passage which closes all, and presses home the great warning against trusting to any experience short of the surrender of the life to do the will of God as set forth in the words of Christ His Son. The two classes He has now in view are not the two great classes who walk, the one in the broad and the other in the narrow way. They are two classes of hearers. Most of those that throng the broad way are not hearers at all; they have no desire or intention of seeking any other than the broad way – they would as little think of going up into a mountain and listening to a discourse on righteousness, as they would of wearing a hair shirt or doing any other kind of penance; but those our Lord has now in view all have the idea of seeking the right way: their very attitude as hearers shows it – they are all of the church-going class, to translate into modern phrase; and what He fears is that some of them may deceive themselves by imagining that because they hear with interest and attention, perhaps admiration, therefore they are in the narrow way. Accordingly He solemnly warns them that all this may amount to nothing: there may be attention, interest, admiration, full assent to all; but if the hearing is not followed by doing, all is in vain.
It may almost go without saying that, after what our Lord has just been teaching as to the vital connection between the faith of the heart and the "fruits" of the life (vv. 15-23), there is no "legalism" here. In fact, the doing is not outward; it is a doing of the heart. The righteousness He has been expounding has, as we have seen, been a righteousness of the heart, and the doing of it, as a matter of course, is a heart-work, having its root in faith, which is the beginning of the doing in every case, according to His own word in another place: "This is the work of God, that ye believe on Him Whom He hath sent."
The illustration with which He presses home the warning is in the highest
