“Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.”
King James Version (KJV)
3:30 Seeing it is one God who - Shows mercy to both, and by the very same means.
Ro 3:30 Seeing [it is] one God which shall justify. As there is one God, there is one plan of justification. The circumcision, the Jews are justified by faith, a faith not in God, whom they already acknowledged, but a faith in Christ, God manifest in the flesh. In the same way the uncircumcision, the Gentile world, are justified through faith. The Gospel is meant by "the faith" (the article is found in the Greek). The salvation of both is by faith in Christ crucified.
