What does Romans 4:6 mean?
Paul has held up Abraham as an example from Scripture. His intent is to show that God declares people righteous in His sight based on their faith and not on their works (Romans 4:1–5). Paul is not only seeking to prove that salvation comes through faith, not works, but that this idea is not something new. Rather, it's part of the message God has already established. Now Paul turns to something written by another hero of the Israelites: King David of the golden age of Israel.Paul writes that David also speaks of those God declares righteous "apart from works," or in spite of their lack of works. David calls them blessed in the passage Paul will quote in the following verses. In a sense, Paul asks his readers to open their copies of Scripture to the familiar passage of Psalm 32:1–2, to read along as he further proves his point.
Romans 4:1–12 focuses on the faith of Abraham, referenced by Paul to further his case about faith. God only declares people righteous based on their faith in Him. David, as well, describes those against whom God will not count their sin as ''blessed.'' Paul insists that this blessing of being declared righteous by God is available to both the circumcised and the uncircumcised. After all, God declared Abraham righteous long before he was circumcised. In that way, he became the spiritual father of both the believing Gentiles and the believing Jews.
Romans 4 is all about the faith of Abraham. God declared Abraham righteous because of his faith, not because of his works. A declaration of righteousness was God's gift, not a payment. This righteousness is available to everyone, circumcised or not. God declared Abraham righteous many years before he was circumcised, making him the spiritual father of all who believe, whether circumcised or not, whether Jew or Gentile. God's promises to Abraham and his offspring can't be received by keeping the law, only by faith. Abraham's faith in God's promise of a son with Sarah did not waver even as he grew older. God will declare us righteous, as well, if by faith we believe in the God who delivered Jesus to die for our sins and raised Him back to life for our justification.
