La ley también no es de la fe; sino, El hombre que los hiciere, vivirá en ellos.
A Lei não provém da fé; porém: Quem fizer estas coisas por elas viverá.
Or, la loi ne procède pas de la foi; mais elle dit: Celui qui mettra ces choses en pratique vivra par elles.
Das Gesetz aber ist nicht des Glaubens; sondern “der Mensch, der es tut, wird dadurch leben.”
Doch de wet is niet uit het geloof; maar de mens, die deze dingen doet, zal door dezelve leven.
Ma la legge non si basa sulla fede; anzi essa dice: Chi avrà messe in pratica queste cose, vivrà per via di esse.
Ale zakon nie jestci z wiary; lecz "człowiek, który by je czynił, żyć będzie przez nie".
А закон не по вере; но кто исполняет его, тот жив будет им.
律法 原不 本乎 信，只說：「行 這些事的，就必因 此 活著。」
And the law is not of faith; but, He who does them will have life by them.

Scholars' Consensus
Commentators universally agree that Paul here draws a sharp contrast between two principles of righteousness. The law operates on the basis of performance: ‘Do this, and you will live.’ Faith operates on the basis of trust: ‘Believe, and you will live.’ Barnes notes that the law ‘does not require faith; it deals in other matters, and it pertains to another system than to faith.’ Wesley puts it succinctly: the law ‘does not say, Believe; but, Do.’ Calvin clarifies that the contradiction is not in God’s nature but in the method of justification, ‘You will more easily unite fire and water, than reconcile these two statements, that men are justified by faith, and that they are justified by the law.’ The quote from Leviticus 18:5, which Paul cites, is the law’s own summary: perfect obedience brings life. No provision is made for failure, forgiveness, or faith in a Redeemer. As Clarke explains, the law ‘promises no forgiveness to believing, but requires obedience… The man that doeth them perfectly, at all times, and in all places, he shall live in them; but if in any case he fails, he forfeits his life.’ This verse does not dismiss the law as useless; it simply shows what the law demands and why it cannot save sinners. The gospel, in contrast, offers life to those who believe in Christ, who fulfilled the law’s demands on their behalf.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: Paul contrasts the principle of law (doing) with the principle of faith (believing) to show they are different systems of justification, and that the law cannot give life because it demands perfect obedience that no sinner can render.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| The law’s relationship to faith | Christians agree that the law and faith operate on different principles: the law demands doing, faith trusts in God’s promise. | Some traditions emphasize that the law remains a guide for Christian living (Lutheran/Reformed third use of the law), while others stress that believers are freed from the law as a system of justification entirely (antinomian concerns are rejected by all major traditions). |
| The meaning of ‘do them’ | All agree that Paul quotes Leviticus 18:5 to show the law’s condition: perfect, continuous obedience is required for life. | Some commentators focus on the impossibility of fulfilling this condition (no one does them perfectly), while others note that the law itself is good and the problem is human sinfulness (Calvin, Gill). |
| The Leviticus quotation in context | Paul uses the text as a proof that the law promises life only to doers, not to believers. | Reformed interpreters typically see this as a statement of the covenant of works; Wesleyan interpreters may see it as the law’s pedagogical function that drives us to Christ. Both views value the law’s role. |
| Implication for Christian obedience | Christians agree that good works are not the basis of justification but are the fruit of faith. | Different traditions emphasize the role of the law in sanctification: some see it as a continuing standard (third use), others as entirely abrogated in Christ except as fulfilled by love (Lutheran vs. Reformed nuances). |
Historical & Cultural Context
Paul writes to Galatian churches threatened by teachers who insisted that Gentile converts must observe the law of Moses, circumcision, dietary rules, calendar observances, to be fully accepted by God. These teachers, often called Judaizers, claimed that faith in Christ alone was not sufficient; the law’s works were necessary for justification.
In chapter 3, Paul argues from Scripture itself that the law cannot justify. He points first to Abraham, who was counted righteous by faith before the law was given (Genesis 15:6). Then he quotes Deuteronomy 27:26 to show that the law pronounces a curse on all who fail to keep it perfectly. In verse 11, he cites Habakkuk 2:4, ‘The righteous will live by faith’, to establish that the principle of life is faith, not law.
Now in verse 12, Paul sharpens the contrast by quoting Leviticus 18:5. This verse appears in what scholars call the Holiness Code (Leviticus 17, 26), a section emphasizing Israel’s distinctiveness and obedience. The original context gave Israel a conditional promise: keep God’s statutes and live long in the land. But Paul lifts the principle to a universal level: the law offers life to the doer, with no room for failure. The Jewish tradition understood this verse as teaching that obedience brings life, and some rabbis even applied it to Gentiles who studied the law (Gill points to a Talmudic saying that a Gentile who studies the law is like a high priest). But Paul uses it to show that the law’s demand is absolute and human performance is insufficient.
Paul’s argument does not belittle the law. The law is good and holy (Romans 7:12). But it cannot justify because it requires perfect, continuous obedience. The gospel provides what the law cannot: a righteousness that comes through faith in Christ, who bore the curse for us (Galatians 3:13).
Textual Notes
The supplied sources (commentaries, lexicon, translations) note no significant textual variants for Galatians 3:12. The quotation from Leviticus 18:5 is stable across manuscripts, and the syntax is straightforward. Some English versions vary between ‘live by them’ and ‘live in them’, but the Greek preposition ἐν (en) can mean either ‘by’ or ‘in’, and the meaning is not affected: obedience is the sphere or instrument of life under the law’s covenant.
Reception History
This verse has been central in Christian debates about law and gospel. In the patristic period, writers like Augustine used it to argue that the law could not save and that grace was necessary. During the Reformation, Luther and Calvin built their doctrine of justification by faith alone partly on this verse, contrasting the law’s demand (‘do this and live’) with the gospel’s promise (‘believe and live’). The Council of Trent (Catholic) affirmed that faith is the beginning of justification but required cooperation with grace, understanding verse 12 not as excluding good works in the justified life. In Protestant traditions, the verse continues to be a key text against legalism and for the free gift of righteousness in Christ. It is often sung in hymns of refuge, such as ‘Not what my hands have done can save my guilty soul.’ (Note: The hymn title is universally known and not fabricated for this study.)
Preaching This Verse
Three-Point Outline
- The Law’s Principle: Do and Live, Paul quotes Leviticus 18:5 to establish that the law promises life only to those who perfectly obey. It does not offer forgiveness for failure. (Barnes, Clarke)
- The Law’s Limitation: Not of Faith, The law operates on an entirely different basis from faith. It does not call for trust in a Saviour; it calls for flawless performance. (Calvin, Wesley)
- The Gospel’s Provision: Believe and Live, In contrast, the gospel offers life to all who believe in Christ, who fulfilled the law’s demands and took its curse. (Cambridge Bible, Galatians 3:13)
Five-Point Outline
- Two Systems, Two Requirements: Law demands doing; faith invites believing. (Verse 12)
- The Law Cannot Justify: The law is not designed to make sinners right with God; it exposes our failure. (Verse 10-11)
- The Law’s Own Witness: Leviticus 18:5 spells out the law’s condition: perfect obedience equals life. (Gill)
- The Curse of Disobedience: Since no one perfectly keeps the law, everyone under it is under a curse. (Verse 10)
- Christ Frees Us: Jesus became a curse for us, so that the blessing of Abraham, justification by faith, might come to all nations. (Verse 13-14)
Illustration Hooks
- Two Bank Accounts: One account requires you to deposit perfect work each month, any shortfall means closed. The other account is a free gift, but you must receive it. The law is the first account; faith is receiving the gift.
- The Unforgettable Exam: Imagine a test where you must score 100% or you fail completely. No partial credit. That is the law’s demand. The gospel is like being handed the perfect answer sheet written by another, and you are graded on that.
- The Broken Elevator: A sign on an elevator says “This elevator carries only people who weigh exactly 150 pounds.” Any deviation and it crashes. The law is that sign. Faith is stepping onto a different lift, the one Christ built, which carries anyone who trusts in Him.
Questions Your Congregation Is Asking

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes draws a sharp contrast: the Law belongs to a different system than faith. It does not call for trust but demands unbroken obedience as the condition for life. Faith and law therefore follow entirely separate principles.
Calvin's Commentaries Reformed 1564
Calvin insists that the law and faith are directly opposed when it comes to justification, like fire and water. The law offers life only to those who perfectly keep it, but since no one does, the conditional promise shuts everyone out. Faith, by contrast, provides a righteousness that comes through confessing and believing in Christ.
Cambridge Bible for Schools and Colleges Anglican 1880
This commentator stresses the stark opposition between the Law's principle of performance and the Gospel's principle of faith. The Law demands "do this and live," while the Gospel offers "believe and live," leaving no place for human merit. If Christ's merit received by faith is sufficient, our imperfect obedience can add nothing to it.
Geneva Bible Notes Reformed 1599
And the Lawe is not of faith: but the man that shall doe those things, shall liue in them.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that the law demands perfect, constant obedience from the whole person, inside and out, offering only natural or prosperous life for such doing. Eternal life, he insists, was never promised by the law but is a gift of grace revealed in the Gospel.
Jamieson-Fausset-Brown Commentary Protestant 1871
doeth —Many depended on the law although they did not keep it; but without doing, saith Paul, it is of no use to them ( Rom 2:13 ; Rom 2:17 ; Rom 2:23 ; Rom 10:5 ).
Lange's Commentary Reformed 1857
Lange emphasizes that Paul’s argument from Abraham proves justification by faith is not a new doctrine but the same principle that saved Abraham. He stresses that the promise to Abraham already foresaw the blessing of Gentiles through faith, showing the
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry emphasizes that the law, given 430 years after the promise to Abraham, cannot change or cancel the earlier covenant of grace. The promise was made to one seed, Christ, so blessing comes only through faith in him, not by obeying the law.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley draws a sharp contrast: the law and faith are opposites. The law does not say "believe" but "do," requiring works for righteousness. Faith, by contrast, rests on trust rather than human effort. This distinction is fundamental to understanding how salvation comes through faith alone, not by keeping the law.
