Cambridge Greek Testament Commentary
Romans 10 - Introduction
This chapter expands the theme of the last section, and, by showing that Israel failed through ignorance, culpable because in defiance of express warnings, illustrates one strain in the theme of c. 9 that man is responsible for his failure to respond to GOD’S purposes.
(1–4) Israel’s rejection of the Messiah due to ignorance of the relation of Christ to law and righteousness (5–15) though the demand of the new righteousness was not hard to meet and they were informed of it by (16–21) preaching of the apostles and warnings of the prophets.
