(14) Shall be preached in all the world.--The words must not be strained beyond the meaning which they would have for those who heard them, and they were certain to see in "all the world" (literally, the inhabited earth, as in Luke 2:1; Acts 11:28) neither more nor less than the Roman empire; and it was true, as a matter of fact, that there was hardly a province of the empire in which the faith of Christ had not been preached before the destruction of Jerusalem. Special attention should be given to the words, "a witness unto all the nations," i.e., to all the Gentiles, as an implicit sanction of the work of which St. Paul was afterwards the great representative. So taken, the words prepare the way for the great mission of Matthew 28:19.

Verse 14. - This gospel of the kingdom. The good news of the coming of Messiah's kingdom - what we call in short, "the gospel" - "that God was in Christ reconciling the world unto himself" (2 Corinthians 5:19). He calls it "this" (Matthew 26:13), because it is that which he preached, which it was the object of his incarnation to set forth. In all the world (e)n o%lh"" th = "" oi)koume/nh"", in all the inhabited earth). Before the taking of Jerusalem, the gospel had been carried into all parts of the then known world. We have very uncertain information about the labours of most of the apostles, but if we may judge of their extent from what we know of St. Paul's, we should say that very few quarters of the Roman world were left unvisited. "Their sound went out into all the earth, and their words unto the ends of the inhabited world" (Romans 10:18). St. Paul testifies that the gospel was preached to every kingdom under heaven (Colossians 1:6, 23). He himself carried it to Arabia, Syria, Asia Minor, Greece, Illyricum, Rome, Spain (see Romans 15:19, 24, 28; Galatians 1:17; Philippians 1:13, etc.). A witness unto all [the] nations. That both Jews and Gentiles might have the opportunity of receiving or rejecting Christ. The witness should be for or against them according to the use made of this opportunity. If the gospel thus delivered contained this utterance of our Lord's, the fulfilment of the predictions would lead to belief in him, and could fail to win acceptance only by reason of invincible prejudice or wilful perversity. Shortly, the truth is that the gospel will be everywhere offered, but not everywhere received. And then, when all these signs, especially the one last named, shall have appeared, shall the end come, primarily of Jerusalem, secondarily of this world or this age. Nothing is said of the effect of missionary efforts in early days or in time to come. We know that there was no national conversion in the primitive era, however common individual conversion may have been. So in the present age we are not to expect more than that Christian missions shall reach the uttermost parts of the earth, and that all nations shall have the offer of salvation, before the final appearance of Christ. The success of these efforts at universal evangelization is a mournful problem. "When the Son of man cometh, shall he find the faith upon the earth?" (Luke 18:8).

24:4-28 The disciples had asked concerning the times, When these things should be? Christ gave them no answer to that; but they had also asked, What shall be the sign? This question he answers fully. The prophecy first respects events near at hand, the destruction of Jerusalem, the end of the Jewish church and state, the calling of the Gentiles, and the setting up of Christ's kingdom in the world; but it also looks to the general judgment; and toward the close, points more particularly to the latter. What Christ here said to his disciples, tended more to promote caution than to satisfy their curiosity; more to prepare them for the events that should happen, than to give a distinct idea of the events. This is that good understanding of the times which all should covet, thence to infer what Israel ought to do. Our Saviour cautions his disciples to stand on their guard against false teachers. And he foretells wars and great commotions among nations. From the time that the Jews rejected Christ, and he left their house desolate, the sword never departed from them. See what comes of refusing the gospel. Those who will not hear the messengers of peace, shall be made to hear the messengers of war. But where the heart is fixed, trusting in God, it is kept in peace, and is not afraid. It is against the mind of Christ, that his people should have troubled hearts, even in troublous times. When we looked forward to the eternity of misery that is before the obstinate refusers of Christ and his gospel, we may truly say, The greatest earthly judgments are but the beginning of sorrows. It is comforting that some shall endure even to the end. Our Lord foretells the preaching of the gospel in all the world. The end of the world shall not be till the gospel has done its work. Christ foretells the ruin coming upon the people of the Jews; and what he said here, would be of use to his disciples, for their conduct and for their comfort. If God opens a door of escape, we ought to make our escape, otherwise we do not trust God, but tempt him. It becomes Christ's disciples, in times of public trouble, to be much in prayer: that is never out of season, but in a special manner seasonable when we are distressed on every side. Though we must take what God sends, yet we may pray against sufferings; and it is very trying to a good man, to be taken by any work of necessity from the solemn service and worship of God on the sabbath day. But here is one word of comfort, that for the elect's sake these days shall be made shorter than their enemies designed, who would have cut all off, if God, who used these foes to serve his own purpose, had not set bounds to their wrath. Christ foretells the rapid spreading of the gospel in the world. It is plainly seen as the lightning. Christ preached his gospel openly. The Romans were like an eagle, and the ensign of their armies was an eagle. When a people, by their sin, make themselves as loathsome carcasses, nothing can be expected but that God should send enemies to destroy them. It is very applicable to the day of judgment, the coming of our Lord Jesus Christ in that day, 2Th 2:1. Let us give diligence to make our calling and election sure; then may we know that no enemy or deceiver shall ever prevail against us.And this Gospel of the kingdom,.... Which Christ himself preached, and which he called and sent his apostles to preach, in all the cities of Judah; by which means men were brought into the kingdom of the Messiah, or Gospel dispensation; and which treated both of the kingdom of grace and glory, and pointed out the saints' meetness for the kingdom of heaven, and their right unto it, and gives the best account of the glories of it:

shall be preached in all the world; not only in Judea, where it was now confined, and that by the express orders of Christ himself; but in all the nations of the world, for which the apostles had their commission enlarged, after our Lord's resurrection; when they were bid to go into all the world, and preach the Gospel to every creature; and when the Jews put away the Gospel from them, they accordingly turned to the Gentiles; and before the destruction of Jerusalem, it was preached to all the nations under the heavens; and churches were planted in most places, through the ministry of it:

for a witness unto all nations; meaning either for a witness against all such in them, as should reject it; or as a testimony of Christ and salvation, unto all such as should believe in him:

and then shall the end come; not the end of the world, as the Ethiopic version reads it, and others understand it; but the end of the Jewish state, the end of the city and temple: so that the universal preaching of the Gospel all over the world, was the last criterion and sign, of the destruction of Jerusalem; and the account of that itself next follows, with the dismal circumstances which attended it.
