What does Romans 3:29 mean?
Paul knew that some religious Jews would object to what He was writing. Many still believed they would not be judged by God for their own personal sin because they were circumcised and followed the law—because they were law-observant Jews. Paul has carefully dismantled the logic behind that belief. First, nobody can follow the law perfectly, which means nobody can be deemed righteous in God's eyes on the basis of the law (Romans 3:10). Second, God holds all people to the same moral standards, since He gives all people an opportunity to recognize and seek Him (Romans 1:18–20).Now Paul continues with two questions: Is God only the God of the Jews? Many Jews throughout Israel's history may have said yes to that question. Paul says "No, God is also the God of the Gentiles—the non-Jews." He is the only God, after all. All people must answer to Him. Therefore, it makes sense that God's perfect, ultimate, righteous judgment would carry the same standards for all people.
Romans 3:21–31 finally introduces the ''good news'' part of the gospel of Jesus Christ. Up to this point, Paul has shown that even following the law cannot spare us from being judged by God for our sin. Now Paul announces that, through faith in Christ, we can be made righteous in God's sight. Entirely apart from the law, we can be redeemed by the atoning sacrifice of Christ's blood, willingly shed for our sin. This gift of God's grace instead of wrath is available to everyone, Jews and Gentiles alike. This is truly good news!
Romans 3 begins with a question-and-answer scheme. These are responses one might expect from someone opposed to what Paul wrote in Romans 2. Next, Paul quotes from a series of Old Testament passages. These Scriptures show that those writers also agreed that nobody, not one person, deserves to be called righteous. Paul declares emphatically that no one will be justified by following the works of the law. Finally, though, he arrives at the good news: righteousness before God is available apart from the law through faith in Christ's death for our sin on the cross.
