Is he the God ... - The Jews supposed that he was the God of their nation only, that they only were to be admitted to his favor. In these verses Paul showed that as all had alike sinned, Jews and Gentiles; and as the plan of salvation by faith was adapted to sinners, without any special reference to Jews; so God could show favors to all, and all might be admitted on the same terms to the benefits of the plan of salvation.

It is one God - The same God, there is but one, and his plan is equally suited to Jews and Gentiles.

The circumcision - Those who are circumcised - the Jews.

The uncircumcision - Gentiles; all who were not Jews.

By faith ...through faith - There is no difference in the meaning of these expressions. Both denote that faith is the instrumental cause of justification, or acceptance with God.

Is he the God of the Jews only? - Do not begin to suppose that because you cannot be justified by the works of the law and God has in his mercy found out a new method of saving you, that therefore this mercy shall apply to the Jews exclusively. Is not God the maker, preserver, and redeemer, also of the Gentiles? Yes, of the Gentiles also, as much as of the Jews; for all have equally sinned and there is no reason, if God be disposed to show mercy at all, that he should prefer the one to the other; since they are all equally guilty, sinful, and necessitous.

Is he the God of the Jews only?.... The Jews made their boast of him as such, and would not allow the Gentiles any interest in him: but

is he not also of the Gentiles? yes, of the Gentiles also: God is the God both of Jews and Gentiles; not only as the Creator, preserver, and Governor of them, or as he has a right to demand worship and service of them, but as he is their covenant God; not by virtue of the covenant of circumcision, or by the Sinai Covenant, but by the covenant of grace; as appears by his loving them in Christ, choosing them in him, putting them into his hands, providing blessings of grace for them in him, and sending his Son to redeem them; by calling them by his grace; by their sanctification, adoption, pardon, and justification; by taking out of them a people for his name with whom he dwells, and of whom he takes care; and will never leave nor forsake: all which may lead us to observe the distinguishing grace of God, the happiness of our state and condition, and what encouragement we have for faith and hope in God.

{12} Is he the God of the {f} Jews only? is he not also of the Gentiles? Yes, of the Gentiles also:

(12) Another absurd argument: if justification depended upon the law of Moses, then God would be a Saviour to the Jews only. Again, if he would save the Jews after one manner, and the Gentiles after another, he would not be consistent. Therefore he will justify both of them after the very same manner, that is to say, by faith. Moreover, this argument must be joined to that which follows next, so that his conclusion may be firm and evident.

(f) God is said to be their God, after the manner of the scripture, whom he loves and cares for.

3:29 Is he the God of the Jews only? If God is the God of all nations, it ought to be regarded a reasonable thing that he would justify through faith Gentiles as well as Jews.

3:29 Surely of the gentiles also - As both nature and the scriptures show.

29. Is he the God of the Jews only? &c.-The way of salvation must be one equally suited to the whole family of fallen man: but the doctrine of justification by faith is the only one that lays the basis of a Universal Religion; this therefore is another mark of its truth.

3:27-31 God will have the great work of the justification and salvation of sinners carried on from first to last, so as to shut out boasting. Now, if we were saved by our own works, boasting would not be excluded. But the way of justification by faith for ever shuts out boasting. Yet believers are not left to be lawless; faith is a law, it is a working grace, wherever it is in truth. By faith, not in this matter an act of obedience, or a good work, but forming the relation between Christ and the sinner, which renders it proper that the believer should be pardoned and justified for the sake of the Saviour, and that the unbeliever who is not thus united or related to him, should remain under condemnation. The law is still of use to convince us of what is past, and to direct us for the future. Though we cannot be saved by it as a covenant, yet we own and submit to it, as a rule in the hand of the Mediator.
