“But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;”
King James Version (KJV)
3:21 But now the righteousness of God - That is, the manner of becoming righteous which God hath appointed. Without the law - Without that previous obedience which the law requires; without reference to the law, or dependence on it. Is manifested - In the gospel. Being attested by the Law itself, and by the Prophets - By all the promises in the Old Testament.
Ro 3:21 The righteousness of God without from the law is manifested. In Greek, "without law". A righteousness that does not spring from perfect obedience to law ("without law"), is predicted both by the law of Moses and the prophets of Israel.
