Purpose of law in Galatians 3:21?
What does Galatians 3:21 reveal about the purpose of the law?

Galatians 3:21—The Text in Focus

“Is the law, therefore, opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, righteousness would certainly have come from the law.”


Key Truths Drawn from the Verse

• The law is not in conflict with God’s promises.

• Scripture affirms the law cannot impart life.

• If righteousness could come through a legal code, salvation by law-keeping would suffice—but it cannot.


Purpose of the Law Highlighted

1. Revelatory, not Redemptive

Romans 3:20: “Through the law we become conscious of sin.”

Romans 7:7: Paul learned what sin was by the command, “Do not covet.”

2. Complementary, not Contrary, to the Promise

– The law exposes humanity’s need so the promise of life in Christ shines brighter (Galatians 3:22).

3. Temporary Custodian

Galatians 3:24: “So the law became our guardian to lead us to Christ, that we might be justified by faith.”

4. Moral Mirror

1 Timothy 1:8-11: The law is good when used properly—to expose sin and uphold God’s moral order.

5. Silent on Giving Life

– “If a law had been given that could impart life…”—but no such law exists; only Christ gives life (John 1:17; John 14:6).


Why the Law Cannot Save

• It demands perfection (James 2:10).

• It carries a curse for transgressors (Galatians 3:10).

• Human nature is enslaved to sin (Romans 7:14-24).

• Life requires a new heart, not mere external compliance (Ezekiel 36:26-27).


How the Law Serves the Promise

– By highlighting sin, it drives sinners to God’s gracious promise in Christ.

– By preserving Israel morally and ceremonially, it prepared a context for Messiah’s arrival.

– By foreshadowing sacrificial atonement, it pointed ahead to the cross (Hebrews 10:1-4).


Takeaway for Today

• Honor the law as God’s righteous standard.

• Use it as a diagnostic tool, not a ladder to climb.

• Run to Christ for the life and righteousness the law shows we lack.
