Acts 13:40

See then that you reject not this divine Saviour, lest what has been denounced by the prophets fall upon your incredulous heads: I will abandon the holy place which I entrusted to you; I will cease to look upon you as my people; I will transfer my kingdom to the Gentiles. (Bible de Vence)

[b.] It is at their utmost peril if they reject the gospel of Christ, and turn their backs upon the offer now made them (v. 40, 41): Beware therefore; you have a fair invitation given you, look to yourselves, lest you either neglect or oppose it." Note, Those to whom the gospel is preached must see themselves upon their trial and good behaviour, and are concerned to beware lest they be found refusers of the grace offered. "Beware lest you not only come short of the blessings and benefits spoken of in the prophets as coming upon those that believe, but fall under the doom spoken of in the prophets as coming upon those that persist in unbelief: lest that come upon you which is spoken of." Note, The threatenings are warnings ; what we are told will come upon impenitent sinners is designed to awaken us to beware lest it should come upon us. Now the prophecy referred to we have Hab 1 5, where the destruction of the Jewish nation by the Chaldeans is foretold as an incredible unparalleled destruction; and this is here applied to the destruction that was coming upon that nation by the Romans, for their rejecting the gospel of Christ. The apostle follows the Septuagint translation, which reads, Behold, you despisers (for, behold, you among the heathen); because it made the text more apposite to his purpose. 1st, "Take heed lest the guilt come upon you which was spoken of in the prophets—the guilt of despising the gospel and the tenders of it, and despising the Gentiles that were advanced to partake of it. Beware lest it be said to you, Behold, you despisers." Note, It is the ruin of many that they despise religion, they look upon it as a thing below them, and are not willing to stoop to it. 2ndly, "Take heed lest the judgment come upon you which was spoken of in the prophets: that you shall wonder and perish, that is, wonderfully perish; your perdition shall be amazing to yourselves and all about you." Those that will not wonder and be saved shall wonder and perish. Those that enjoyed the privileges of the church, and flattered themselves with a conceit that these would save them, will wonder when they find their vain presumption overruled and that their privileges do but make their condemnation the more intolerable. Let the unbelieving Jews expect that God will work a work in their days which you shall in no wise believe, though a man declare it unto you. This may be understood as a prediction, either, 1. Of their sin, that they should be incredulous, that that great work of God, the redemption of the world by Christ, though it should be in the most solemn manner declared unto them, yet they would in no wise believe it, Isa 53 1, Who hath believed our report? Though it was of God's working, to whom nothing is impossible, and of his declaring, who cannot lie, yet they would not give credit to it. Those that had the honour and advantage to have this work wrought in their days had not the grace to believe it. Or, 2. Of their destruction. The dissolving of the Jewish polity, the taking of the kingdom of God from them and giving it to the Gentiles, the destruction of their holy house and city, and the dispersion of their people, was a work which one would not have believed should have ever been done, considering how much they had been the favourites of Heaven. The calamities that were brought upon them were such as were never before brought upon any people, Matt 24 21. It was said of their destruction by the Chaldeans, and it was true of their last destruction, All the inhabitants of the world would not have believed that the enemy would have entered into the gates of Jerusalem as they did, Lam 4 12. Thus is there a strange punishment to the workers of iniquity, especially to the despisers of Christ, Job 31 3.

Verses 38-41 Let all that hear the gospel of Christ, know these two things: 1. That through this Man, who died and rose again, is preached unto you the forgiveness of sins. Your sins, though many and great, may be forgiven, and they may be so without any injury to God's honour. 2. It is by Christ only that those who believe in him, and none else, are justified from all things; from all the guilt and stain of sin, from which they could not be justified by the law of Moses. The great concern of convinced sinners is, to be justified, to be acquitted from all their guilt, and accepted as righteous in God's sight, for if any is left charged upon the sinner, he is undone. By Jesus Christ we obtain a complete justification; for by him a complete atonement was made for sin. We are justified, not only by him as our Judge but by him as the Lord our Righteousness. What the law could not do for us, in that it was weak, the gospel of Christ does. This is the most needful blessing, bringing in every other. The threatenings are warnings; what we are told will come upon impenitent sinners, is designed to awaken us to beware lest it come upon us. It ruins many, that they despise religion. Those that will not wonder and be saved, shall wonder and perish.
