John Owen expounds on Romans 10:3-4, emphasizing that the Jews, despite their zeal for God, failed to attain righteousness because they sought it through their own works rather than through faith in Christ. He contrasts the Gentiles, who did not pursue righteousness but received it through faith, highlighting the futility of self-righteousness. Owen argues that true righteousness comes from submitting to God's righteousness, which is fulfilled in Christ, the end of the law for all who believe. He warns against the dangers of relying on personal merit and stresses that justification is solely by faith, not by works. Ultimately, Owen calls for a complete reliance on Christ for righteousness and justification before God.
