Romans 3 Summary (Explained)

In Romans 3, the Apostle Paul delivers a profound exploration of righteousness and accountability, setting a foundational tone for the Christian faith.

The chapter’s concluding verses emphasize faith’s role in salvation, inviting readers to embrace a relationship with God that transcends cultural and religious barriers.

All Have Sinned
“What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin; As it is written, There is none righteous, no, not one… There is none that understandeth, there is none that seeketh after God.” — Romans 3:9–12 (KJV)
Commentary 1: Paul emphasizes that sin affects everyone, leaving no one righteous by their own efforts.
Commentary 2: This sets the stage for the need for God’s grace and justification through faith.
God’s Righteousness Through Faith
“But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe…” — Romans 3:21–22 (KJV)
Commentary 1: Righteousness is not earned through the law or works, but given freely by God to those who believe.
Commentary 2: Faith in Christ is the only pathway to true righteousness and reconciliation with God.
Justification as a Gift
“For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus.” — Romans 3:23–24 (KJV)
Commentary 1: Justification is a gift from God, not a reward for human effort.
Commentary 2: Redemption through Christ restores our relationship with God and removes the penalty of sin.
Christ as the Sacrifice
“Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.” — Romans 3:25–26 (KJV)
