Acts 14:16

He left not himself without testimony. Inasmuch as the Gentiles had always the light of reason, and such lights, that by the created things of this world, and from the visible effects of God’s providence, they might have come to the knowledge of the true God, the creator of all things. See Romans chap. i. (Witham) — God did not leave himself without testimony among the Gentiles. He did not leave them without the means of discovering the way which led to him. They had the law of nature engraved in their hearts, the knowledge of good and evil, &c. (Menochius) — Therefore they were inexcusable, if they did not know him. The invisible things of God, his eternal divinity might have been known to them from the consideration of the visible creation. (Romans i. 20.)

Fourthly, That the world owed it to his patience that he had not destroyed them long ere this for their idolatry (v. 16): In times past, for many ages, unto this day, he suffered all nations to walk in their own ways. These idolaters, that were called from the service of other gods, might think, "Have we not served these gods hitherto, and our fathers before us, time out of mind; and why may we not as well go on to serve them still?"—No, your serving them was a trial of God's patience, and it was a miracle of mercy that you were not cut off for it. But, though he did not destroy you for it while you were in ignorance, and knew no better (ch. 17 30) yet now that he has sent his gospel into the world, and by it has made a clear discovery of himself and his will to all nations, and not to the Jews only, if you still continue in your idolatry he will not bear with you as he has done. All the nations that had not the benefit of divine revelation, that is, all but the Jews, he suffered to walk in their own ways, for they had nothing to check them, or control them, but their own consciences, their own thoughts (Rom 2 15), no scriptures, no prophets; and then they were the more excusable if they mistook their way: but now that God has sent a revelation into the world which is to be published to all nations the case is altered. We may understand it as a judgment upon all nations that God suffered them to walk in their own ways, gave them up to their own hearts' lusts; but now the time is come when the veil of the covering spread over all nations should be taken off (Isa 25 7), and now you will no longer be excused in these vanities, but must turn from them. Note, 1. God's patience with us hitherto should lead us to repentance, and not encourage us to presume upon the continuance of it, while we continue to provoke him. 2. Our having done ill while we were in ignorance will not bear us out in doing ill when we are better taught.

Verses 8-18 All things are possible to those that believe. When we have faith, that most precious gift of God, we shall be delivered from the spiritual helplessness in which we were born, and from the dominion of sinful habits since formed; we shall be made able to stand upright and walk cheerfully in the ways of the Lord. When Christ, the Son of God, appeared in the likeness of men, and did many miracles, men were so far from doing sacrifice to him, that they made him a sacrifice to their pride and malice; but Paul and Barnabas, upon their working one miracle, were treated as gods. The same power of the god of this world, which closes the carnal mind against truth, makes errors and mistakes find easy admission. We do not learn that they rent their clothes when the people spake of stoning them; but when they spake of worshipping them; they could not bear it, being more concerned for God's honour than their own. God's truth needs not the services of man's falsehood. The servants of God might easily obtain undue honours if they would wink at men's errors and vices; but they must dread and detest such respect more than any reproach. When the apostles preached to the Jews, who hated idolatry, they had only to preach the grace of God in Christ; but when they had to do with the Gentiles, they must set right their mistakes in natural religion. Compare their conduct and declaration with the false opinions of those who think the worship of a God, under any name, or in any manner, is equally acceptable to the Lord Almighty. The most powerful arguments, the most earnest and affectionate addresses, even with miracles, are scarcely enough to keep men from absurdities and abominations; much less can they, without special grace, turn the hearts of sinners to God and to holiness.
