Who will render to every one, etc. As he had to do with blind saintlings, who thought that the wickedness of their hearts was well covered, provided it was spread over with some disguises, I know not what, of empty works, he pointed out the true character of the righteousness of works, even that which is of account before God; and he did this, lest they should feel confident that it was enough to pacify him, if they brought words and trifles, or leaves only. But there is not so much difficulty in this verse, as it is commonly thought. For the Lord, by visiting the wickedness of the reprobate with just vengeance, will recompense them with what they have deserved: and as he sanctifies those whom he has previously resolved to glorify, he will also crown their good works, but not on account of any merit: nor can this be proved from this verse; for though it declares what reward good works are to have, it does yet by no means show what they are worth, or what price is due to them. And it is an absurd inference, to deduce merit from reward.

Who will render - That is, who will make retribution as a righteous Judge; or who will give to every man as he deserves.
To every man - To each one. This is a general principle, and it is clear that in this respect God would deal with the Jew as he does with the Gentile. This general principle the apostle is establishing, that he may bring it to bear on the Jew, and to show that he cannot escape simply because he is a Jew.
According to his deeds - That is, as he deserves; or God will be just, and will treat every man as he ought to be treated, or according to his character. The word "deeds" (ἔργα erga)is sometimes applied to the external conduct. But it is plain that this is not its meaning here. It denotes everything connected with conduct, including the acts of the mind, the motives, the principles, as well as the mere external act. Our word character more aptly expresses it than any single word. It is not true that God will treat people according to their external conduct: but the whole language of the Bible implies that he will judge people according to the whole of their conduct, including their thoughts, and principles, and motives; that is, as they deserve. The doctrine of this place is abundantly taught elsewhere in the Bible, Proverbs 24:12; Matthew 16:27; Revelation 20:12; Jeremiah 32:19. It is to be observed here that the apostle does not say that people will be rewarded for their deeds, (compare Luke 17:10,) but according to κατά kata their deeds. Christians will be saved on account of the merits of the Lord Jesus Christ, Titus 3:5, but still the rewards of heaven will be according to their works; that is, they who have labored most, and been most faithful, shall receive the highest reward, or their fidelity in their Master's service shall be the measure or rule according to which the rewards of heaven shall be distributed, Matthew. 25:14-29. Thus, the ground or reason why they are saved shall be the merits of the Lord Jesus. The measure of their happiness shall be according to their character and deeds. On what principle God will distribute his rewards the apostle proceeds immediately to state.

Who will render - Who, in the day of judgment, will reward and punish every man according as his life and conversation have been.

(3) Who will render to every man according to his deeds:
(3) The foundation of the former disputation, that both the Jews and Gentiles together have need of righteousness.

Who will render to every man according to his deeds. God will be the Judge, who is righteous, holy, just, and true; every man in particular will be judged; as the judgment will be general to all, it will be special to everyone, and will proceed according to their works; for God will render to wicked men according to the demerit of their sins, the just recompense of reward, eternal damnation; and to good men eternal life, not according to the merit of their good works, which have none in them, but according to the nature of them; such who believe in Christ, and perform good works from a principle of grace, shall receive the reward of the inheritance, which is a reward of grace, and not of debt. In other words, God will render to evil men according to the true desert of their evil deeds; and of his own free grace will render to good men, whom he has made so by his grace, what is suitable and agreeable to those good works, which, by the assistance of his grace, they have been enabled to perform.
