In times past. Because the men of Lystra might object that that God was unknown hitherto, Paul and Barnabas prevent them and say, that all men wandered indeed in darkness, and that all mankind was stricken with blindness, but that they deny that any prejudice must be made [1] according to the perverse ignorance of the world. These were two no small lets for the unbelievers, long antiquity of time, and the consent almost of all nations. Paul and Barnabas remove both in this place, If, say they, men have erred many years, [ages,] and if the world have wandered without reason and judgment, let not, therefore, the truth of God, when it appeareth, be less precious to you. For seeing that it is eternal, and is not changed, it is an unmeet thing that the long prescription of years should be set against it. They prove that there is no more aid or patronage to be found in the number of men. There is no cause (say they) why the conspiracy of all the whole world should keep you from coming to the right way. Blindness hath got the upper hand among all people; but God doth now (appear and) give light to you. Therefore, your eyes must be open, and you must not slumber and sleep in darkness, though all people have been drowned therein hitherto. Their ways. If he had only said that men were deceived until that time through God's sufferance, we might easily gather thereby that all men can do nothing else but err, so long as they be not governed of God. Yet he speaketh far more plainly when he calleth errors the ways of men. For we are plainly taught by this what the wisdom and understanding of man's mind can do in beholding and keeping the way of salvation. All people [nations] (saith he) have walked in their own ways; that is, they have wandered in darkness and death. It is all one as if he should say, that there is no sparkle of true reason in all the whole world. Therefore, there is but one rule of true godliness, that is, that the faithful, casting from them all confidence in their own wit, do submit themselves to God. For the ways of men are now as they were in times past; and the examples of all times teach how miserably blind those men be who have not the word of God to give them light, though they think they can pass other men in quickness of sight. Immediately after the beginning of the world, the more part fell away unto diverse superstitions and wicked worshippings. Whence came that, save only because it pleased them to follow their own imaginations? When it might have seemed that the world was purged with the flood, it fell again [relapsed] straightway to the same vices. Therefore, there is nothing more deadly than to lean to our own wisdom. But Paul and Barnabas show no cause here why the Lord suffered the world to err so long; and assuredly we must count the will of God alone the chiefest law of equity. God hath always a good reason for his worlds; but because it is oftentimes hid from us, it is our duty reverently to wonder at his secret counsel. We must, indeed, confess that the world was worthy of [deserved] such destruction; but there can no other reason be brought why the Lord had mercy rather on one age than on another, save only because it seemed good to him that it should be so. Therefore, Paul calleth that time which was appointed of God for preaching the gospel, the time of fullness, (Galatians 4:4,) lest any other opportunity be sought. And we must remember that which we had in the first chapter, that it is not for us to know the times and seasons which the Father hath placed in his own power. So that the cavil of the Papists is refuted, who say that it cannot be that God suffered his Church to err so long. For whence, I pray you, came the Gentiles but from the ark of Noah, when there was a certain singular purity of the Church? (Genesis 9:9.) Also, the posterity of holy Shem, together with others, did degenerate. Yea, Israel, the peculiar people of the Lord, was also left for a long time. Wherefore, it is no marvel if God did punish the contempt of his word with the same blindness under the reign of his Son as he did in times past.

Footnotes

1 - "Debere praejudicium fieri," that any thing should be prejudged, (any judgment should be founded on.)

Who in times past - Previous to the gospel; in past ages.
Suffered all nations - Permitted all nations; that is, all Gentiles, Acts 17:30. "And the times of this ignorance God winked at."
To walk in their own ways - To conduct themselves without the restraints and instructions of a written law. They were permitted to follow their own reason and passions, and their own system of religion. God gave them no written laws, and sent to them no messengers. Why he did this we cannot determine. It might have been, among other reasons, to show to the world conclusively:
(1) The insufficiency of reason to guide people in the matters of religion. The experiment was made under the most favorable circumstances. The most enlightened nations, the Greeks and Romans, were left to pursue the inquiry, and failed no less than the most degraded tribes of people. The trial was made for four thousand years, and attended with the same results everywhere.
(2) it showed the need of revelation to guide man.
(3) it evinced, beyond the possibility of mistake, the depravity of man. In all nations, in all circumstances, people had shown the same alienation from God. By suffering them to walk in their own ways, it was seen that those ways were sin, and that some power more than human was necessary to bring people back to God.

Who in times past suffered all nations, etc. - The words παντα τα εθνη, which we here translate, all nations, should be rendered, all the Gentiles, merely to distinguish them from the Jewish people: who having a revelation, were not left to walk in their own ways; but the heathens, who had not a revelation, were suffered to form their creed, and mode of worship, according to their own caprice.

(5) Who in times past (g) suffered all nations to walk in their own ways.
(5) Custom, be it ever so old, does not excuse the idolaters.
(g) Allowed them to live as they wished, prescribing and appointing them no type of religion.

Who in times past,.... For many hundred years past; even ever since God chose and separated the people of Israel from the rest of the nations, to be a peculiar people to himself: from that time he
suffered all nations to walk in their own ways; of ignorance, superstition, and idolatry; which they devised, and chose, and delighted in: not that he gave them any licence to walk in these ways, without being chargeable with sin, or with impunity; but he left them to themselves, to the dim light and law of nature, and gave them no written law, nor any external revelation of his mind and will; nor did he send any prophets or ministers of his unto them, to show them the evil of their ways, and turn them from them, and direct them to the true God, and the right way of worshipping him; but left them to take their own methods, and pursue the imagination of their own hearts: but the apostle suggests, that the case was now altered, and God had sent them and other ministers of his, among all nations of the world, to protest against their superstition and idolatry; and to reclaim them from their evil ways, and to direct them to the true and living God, and his worship, and to preach salvation by his Son Jesus Christ.

Who in times past suffered all nations to walk in their own ways--that is, without extending to them the revelation vouchsafed to the seed of Abraham, and the grace attending it; compare Acts 17:30; 1-Corinthians 1:21. Yet not without guilt on their part was this privation (Romans 1:20, &c.).

Who in times past - He prevents their objection, "But if these things are so, we should have heard the in from our fathers." Suffered - An awful judgment, all nations - The multitude of them that err does not turn error into truth, to walk in their own ways - The idolatries which they had chosen.
