Romans: The Gospel Unites
Paul wrote this letter for the purpose of unity, and he understood Jesus Christ as the great unifying factor.
As for the what, Paul’s apostolic service is (God-)intended to result in obedience. Doctoral dissertations have been written on what “the obedience of faith” means. Two things can be said for sure in brief: (1) True faith in Christ results in obedience to God’s will as Christ and the Scriptures reveal it. Jesus puts it this way: “If you love me, you will keep my commandments” (John 14:15). Living belief in Jesus results in obedience to him—believing obedience. (2) The Christian faith affirms certain things (like Christ’s bodily resurrection) and denies others (like the claim that Jesus is not the only way to salvation). Saving faith is faith that affirms what is in accordance with “the” faith. This means “obedience to the faith”
