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.

31. Do we then make void the law through faith?—"Does this doctrine of justification by faith, then, dissolve the obligation of the law? If so, it cannot be of God. But away with such a thought, for it does just the reverse."

God forbid: yea, we establish the law—It will be observed here, that, important as was this objection, and opening up as it did so noble a field for the illustration of the peculiar glory of the Gospel, the apostle does no more here than indignantly repel it, intending at a subsequent stage of his argument (Ro 6:1-23) to resume and discuss it at length.

Note, (1) It is a fundamental requisite of all true religion that it tend to humble the sinner and exalt God; and every system which breeds self-righteousness, or cherishes boasting, bears falsehood on its face (Ro 3:27, 28). (2) The fitness of the Gospel to be a universal religion, beneath which the guilty of every name and degree are invited and warranted to take shelter and repose, is a glorious evidence of its truth (Ro 3:29, 30). (3) The glory of God's law, in its eternal and immutable obligations, is then only fully apprehended by the sinner, and then only is it enthroned in the depths of his soul, when, believing that "He was made sin for him who knew no sin," he sees himself "made the righteousness of God in Him" (2Co 5:21). Thus do we not make void the law through faith: yea, we establish the law. (4) This chapter, and particularly the latter part of it, "is the proper seat of the Pauline doctrine of Justification, and the grand proof-passage of the Protestant doctrine of the Imputation of Christ's righteousness and of Justification not on account of, but through faith alone" [Philippi]. To make good this doctrine, and reseat it in the faith and affection of the Church, was worth all the bloody struggles that it cost our fathers, and it will be the wisdom and safety, the life and vigor of the churches, to "stand fast in this liberty wherewith Christ hath made them free, and not be again entangled"—in the very least degree—"with the yoke of bondage" (Ga 5:1).
