Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. (28) Therefore we conclude that a man is justified by faith without the deeds of the law. (29) Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also: (30) Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith. (31) Do we then make void the law through faith? God forbid: yea, we establish the law.
The Apostle having shewn, and by means so clear and plain, the way of salvation to be only in Christ, and by Christ; now returns back to his original subject, in relation to the total inability of either Jew, or Gentile, justifying themselves before God. And, to do this with greater, force of argument, he puts every objection which the weakness, or perversity of the human mind, untaught of God, might bring into the form of questions. Where is boasting then? It is excluded. By what law of works? Nay, but by the law of faith. Everything is excluded in the creature, while Christ alone is exalted in the infinite greatness, and glories of his Person, and in the infinite merit of his work, in his blood shedding, and righteousness. The, Jew and Gentile are distinctions but in name, while Christ is all, and in all. For God, as a Covenant God in Christ, is the God of both, in every individual instance of his Church, given by God to Christ, and chosen by God in Christ, before the foundation of the world, Ephesians 1:4. This ancient settlement of eternity took place, not only before the name of Jew or Gentile were known, but before sin had entered into the world to make those distinctions; yea, before the world itself was called into being. And therefore, as the Church of Christ had being in Christ, from everlasting; the recovery of the Church from the Adam-fall by sin, in this time-state of her being, had been all along provided for: and Christ's people, whether Jew or Gentile, were his, and the objects of his love, and grace, and favor, from all eternity. So that He that is the God in Covenant for the Jew, is also for the Gentile; seeing it is His justification of them, whether circumcised or uncircumcised, and not their different claims to favor, which becomes the cause of their acceptance. And so far is all this blessed and approved way, of being wholly justified by Christ, from setting aside the law, that in fact it becomes the only establishment of it. Since it proves, that rather than one jot or tittle of God's holy law should fail; the Son of God shall fulfil all its righteous demands, and give his soul an offering for sin, for the breaches of it by his people. And, it is the joy of all the redeemed, as well in heaven, as earth, that by the obedience and death of Christ, the Son of God in our nature, hath done more to magnify, and make honorable, God's holy law, than could have been done by the unsinning obedience of the whole creation of (God, to all eternity, Daniel 9:24.
