Even as David - The apostle having adduced the example of Abraham to show that the doctrine which he was defending was not new, and contrary to the Old Testament, proceeds to adduce the case of David also; and to show that he understood the same doctrine of justification without works.

Describeth - Speaks of.

The blessedness - The happiness; or the desirable state or condition.

Unto whom God imputeth righteousness - Whom God treats as righteous, or as entitled to his favor in a way different from his conformity to the Law. This is found in Psalm 32:1-11. And the whole scope and design of the psalm is to show the blessedness of the man who is forgiven, and whose sins are not charged on him, but who is freed from the punishment due to his sins. Being thus pardoned, he is treated as a righteous man. And it is evidently in this sense that the apostle uses the expression "imputeth righteousness," that is, he does not impute, or charge on the man his sins; he reckons and treats him as a pardoned and righteous man; Psalm 32:2. See the note at Romans 4:3. He regards him as one who is forgiven and admitted to his favor, and who is to be treated henceforward as though he had not sinned. That is, he partakes of the benefits of Christ's atonement, so as not henceforward to be treated as a sinner, but as a friend of God.

Even as David also, etc. - David, in Psalm 32:1, Psalm 32:2, gives us also the true notion of this way of justification, i.e. by faith, without the merit of works, where he says: -

Even as David also describeth the blessedness of the man,.... the apostle having instanced in Abraham, the father of the Jewish nation, cites some passages from David, king of Israel, a person of great note and esteem among the Jews, in favour of the doctrine he is establishing; who in a very proper and lively manner describes the happiness of such persons:

unto whom God imputeth righteousness without works. This righteousness cannot be the righteousness of the law, or man's obedience to it; for that is a righteousness with works, is a man's own, and not imputed; and indeed is not a righteousness in the sight of God: nor does man's blessedness lie in, or come by it; no man is, or can be instilled by it, nor saved by it, or attain to heaven and eternal happiness by the means of it; but the righteousness here spoken of is the righteousness of Christ, called the righteousness of God; and is better than that of angels or men; is complete and perfect; by which the law is honoured, and justice is satisfied. This is freely bestowed, and graciously "imputed" by God. Just in the same way his righteousness becomes ours, as Adam's sin did, which is by imputation; or in the same way that our sins became Christ's, his righteousness becomes ours; and as we have no righteousness of our own when God justifies us, this must be done by the righteousness of another; and that can be done no other way by the righteousness of another, than by imputing it to us: and which is done "without works"; not without the works of Christ, of which this righteousness consists; but without the works of the creature, or any consideration of them, which are utterly excluded from justification; for if these came into account, it would not be of grace, and boasting would not be removed. Now such who have this righteousness thus imputed to them, are happy persons; they are justified from all sin, and freed from all condemnation; their persons and services are acceptable to God; it will be always well with them; they are heirs of glory, and shall enjoy it.

Describeth the blessedness (λέγει τὸν μακαρισμὸν)

Μακαρισμός does not mean blessedness, but the declaration of blessedness, the congratulation. So Plato: "The man of understanding will not suffer himself to be dazzled by the congratulation (μακαρισμοῦ) of the multitude ("Republic," ix., 591). Compare Galatians 4:15 (Rev.), and see note there. Rev., correctly, pronounceth blessing.

{5} Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,

(5) Another proof of the same confirmation: David puts blessedness as a part of the free pardon of sins, and therefore justification also.

4:6 Even as David also. Paul has shown that Abraham's justification which is not due to our own righteousness, but to God's mercy. Such names as that of Abraham, the father of their race, and David, the great king, would be authoritative with the Jews.

4:6 So David also - David is fitly introduced after Abraham, because be also received and delivered down the promise. Affirmeth - A man is justified by faith alone, and not by works. Without works - That is, without regard to any former good works supposed to have been done by him.

Margin imputed

Or, reckoned, i.e. put to the account of. See Phile 1:18, same word:

6-8. David also describeth-"speaketh," "pronounceth."

the blessedness of the man unto whom the Lord imputeth righteousness without works-whom, though void of all good works, He, nevertheless, regards and treats as righteous.

4:1-12 To meet the views of the Jews, the apostle first refers to the example of Abraham, in whom the Jews gloried as their most renowned forefather. However exalted in various respects, he had nothing to boast in the presence of God, being saved by grace, through faith, even as others. Without noticing the years which passed before his call, and the failures at times in his obedience, and even in his faith, it was expressly stated in Scripture that he believed God, and it was counted to him for righteousness, Ge 15:6. From this example it is observed, that if any man could work the full measure required by the law, the reward must be reckoned as a debt, which evidently was not the case even of Abraham, seeing faith was reckoned to him for righteousness. When believers are justified by faith, their faith being counted for righteousness, their faith does not justify them as a part, small or great, of their righteousness; but as the appointed means of uniting them to Him who has chosen as the name whereby he shall be called, the Lord our Righteousness. Pardoned people are the only blessed people. It clearly appears from the Scripture, that Abraham was justified several years before his circumcision. It is, therefore, plain that this rite was not necessary in order to justification. It was a sign of the original corruption of human nature. And it was such a sign as was also an outward seal, appointed not only to confirm God's promises to him and to his seed, and their obligation to be the Lord's, but likewise to assure him of his being already a real partaker of the righteousness of faith. Thus Abraham was the spiritual forefather of all believers, who walked after the example of his obedient faith. The seal of the Holy Spirit in our sanctification, making us new creatures, is the inward evidence of the righteousness of faith.
