3:29 {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.
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.
