Romans 3:21: law vs. grace relationship?
What does Romans 3:21 teach about the relationship between law and grace?

Setting the Scene

Romans 1–3 builds an airtight case: every human being—Jew and Gentile alike—stands guilty before a holy God. After 3:20 declares, “Therefore no one will be justified in His sight by works of the law,” 3:21 bursts in with hope.


The Key Verse

“ But now, apart from the law, the righteousness of God has been revealed, being witnessed by the Law and the Prophets.” (Romans 3:21)


What “But Now” Signals

• A decisive shift in redemptive history

• God’s intervention when human effort hit a dead end

• A contrast between the old era of condemnation and the new era of revealed righteousness


“Apart from the Law” — What It Does Not Mean

• Not the abolition of the Law’s moral authority (cf. Matthew 5:17)

• Not an excuse for lawlessness (cf. Romans 6:1-2)

• Rather, it means righteousness is not acquired by law-keeping


Law’s True Function

• Exposes sin (Romans 3:20)

• Silences self-justification (Romans 3:19)

• Serves as a tutor leading to Christ (Galatians 3:24)


Grace Steps In

• Righteousness is “revealed” (passive verb—God does the revealing)

• It is God’s own righteousness, credited to believers (Romans 3:22)

• Received “through faith in Jesus Christ to all who believe” (Romans 3:22)


Witnessed by the Law and the Prophets

• The Law foretold substitutionary sacrifice—see Passover lamb (Exodus 12), Day of Atonement (Leviticus 16)

• The Prophets promised a righteous Servant bearing sin—Isaiah 53:5-6

• Grace is not a Plan B; it was embedded in Scripture all along


Harmony Between Law and Grace

1. Law: Reveals the standard → proves our inability

2. Grace: Provides the righteousness the Law demanded → fulfills the standard in Christ

3. Outcome: “The requirement of the Law might be fulfilled in us” (Romans 8:3-4)


Supporting Passages

John 1:17 — “The Law was given through Moses; grace and truth came through Jesus Christ.”

Ephesians 2:8-9 — Salvation is “not of works, so that no one may boast.”

Titus 3:5 — “He saved us, not by works of righteousness we had done, but according to His mercy.”


Living It Out

• Rest from striving: accept the righteousness God freely offers.

• Revere the Law: let it continually remind you why grace is essential.

• Reflect Christ’s righteousness: empowered by the Spirit, live out the moral beauty the Law once commanded but could not supply.
