3:29. Is he the God of the Jews only? Is he not also of the Gentiles? yes, of the Gentiles also.
3:30. For it is one God that justifieth circumcision by faith and uncircumcision through faith.
3:31. Do we then, destroy the law through faith? God forbid! But we establish the law.
Romans Chapter 4
Abraham was not justified by works done, as of himself, but by grace and by faith. And that before he was circumcised. Gentiles, by faith, are his children.
4:1. What shall we say then that Abraham hath found, who is our father according to the flesh?
4:2. For if Abraham were justified by works, he hath whereof to glory, but not before God.
By works. . .Done by his own strength, without the grace of God, and faith in him. Not before God. . .Whatever glory or applause such works might procure from men, they would be of no value in the sight of God.
4:3. For what saith the scripture? Abraham believed God: and it was reputed to him unto justice.
Reputed, etc. . .By God, who reputeth nothing otherwise than it is. However, we may gather from this word, that when we are justified, our justification proceedeth from God's free grace and bounty; and not from any efficacy which any act of ours could have of its own nature, abstracting from God's grace.
