3:30 God is one. Salvation does not come by the possession of the law. This implies that salvation is available to others as well as Jews. Paul confirms this truth in the face of Jewish opposition by appeal to the fundamental confession of Old Testament religion, that God is one (Deut. 6:4). This principle was implied already in the Old Testament prophets’ composite lawsuits against the nations for their sins and against the Jews for theirs (e.g., Amos 1; 2). Paul stresses that justification comes to Jew (“the circumcised”) and to Gentile (“the uncircumcised”) in the same way—by faith alone.
