“To all those in Rome who are loved by God and called to be saints: Grace to you and peace from God our Father and the Lord Jesus Christ” (v7). Paul’s letter addressed “all those in Rome”: both Jews and Gentiles who had come to trust in Jesus as their Savior. He explains that Jesus had been promised in the Hebrew Scriptures; he was David’s descendent according to history but God’s Son according to the resurrection (v2-3). The good news about Jesus was from the Jews but for everyone.
In a world divided by ethnicity and class, tensions present even in the church, Paul’s mission was to bring about “the obedience of faith … among all the nations” (v5).
