Romans 3:30

it is one God who shall justify--"has unchangeably fixed that He shall justify." the circumcision by--"of" faith, and the uncircumcision through faith--probably this is but a varied statement of the same truth for greater emphasis (see Rom 3:22); though BENGEL thinks that the justification of the Jews, as the born heirs of the promise, may be here purposely said to be "of faith," while that of the Gentiles, previously "strangers to the covenants of promise," may be said to be "through faith," as thus admitted into a new family. Objection:

The apostle, in this chapter, carries on his discourse concerning justification. He had already proved the guilt both of Gentiles and Jews. Now in this chapter, I. He answers some objections that might be made against what he had said about the Jews (Rom 3:1-8). II. He asserts the guilt and corruption of mankind in common, both Jews and Gentiles (Rom 3:9-18). III. He argues thence that justification must needs be by faith, and not by the law, which he gives several reasons for (Rom 3:19 to the end). The many digressions in his writings render his discourse sometimes a little difficult, but his scope is evident.
