Paul uses Abraham’s story to prove that justification has always been by faith, not works. By trusting God’s promises, both Jew and Gentile can be made right through Christ.
Abraham’s Faith and Ours: Justified by Believing (Romans 4:1-25)
No Excuses, No Exemptions: God’s Judgment is Impartial (Romans 2:1-29)
In Romans 2, Paul shifts from condemning Gentile sin to exposing Jewish hypocrisy, declaring that all—regardless of heritage—are accountable before God and judged by obedience, not outward appearance.
