Galatians 3:15-25
God's promise to Abraham stands secure in Christ, and the law's temporary role leads us to the faith now revealed in Him.
Scripture Text
3:15 Brothers, speaking of human terms, though it is only a man’s covenant, yet when it has been confirmed, no one makes it void or adds to it.
3:16 Now the promises were spoken to Abraham and to His offspring. He doesn’t say, “To descendants”, as of many, but as of one, “To Your offspring”, which is Christ.
3:17 Now I say this: A covenant confirmed beforehand by God in Christ, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect.
3:18 For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.
3:19 Then why is there the law? It was added because of transgressions, until the offspring should come to whom the promise has been made. It was ordained through angels by the hand of a mediator.
3:20 Now a mediator is not between one, but God is one.
3:21 Is the law then against the promises of God? Certainly not! For if there had been a law given which could make alive, most certainly righteousness would have been of the law.
3:22 But the Scripture imprisoned all things under sin, that the promise by faith in Jesus Christ might be given to those who believe.
3:23 But before faith came, we were kept in custody under the law, confined for the faith which should afterwards be revealed.
3:24 So that the law has become our tutor to bring us to Christ, that we might be justified by faith.
3:25 But now that faith has come, we are no longer under a tutor.
God's promise to Abraham stands secure in Christ, and the law's temporary role leads us to the faith now revealed in Him.
The inheritance rests on God's promise fulfilled in Christ, while the law exposes and confines transgression until the promised Seed brings the people of God into faith's era.
Believers must be rescued from the exhausting attempt to complete by the flesh what God began by the Spirit and must be grounded in Christ's curse-bearing work, promise-secured identity, and Spirit-enabled life.
- Experience of the Spirit exposes the error Paul begins with the Galatians' reception of the Spirit to show that their Christian life began by faith, not works of the law, and therefore cannot be perfected by the flesh.
- Scripture confirms faith as the way of righteousness Abraham Himself was counted righteous by faith, and Scripture announced Gentile blessing through Abraham in advance.
- Law-reliance brings curse, not justification The law demands complete obedience, so those who rely on law-works stand under its curse rather than receiving righteousness.
- Christ bears the curse to bring the blessing Christ's substitutionary curse-bearing redeems believers and brings Abraham's blessing and the promised Spirit to the nations.
- Promise precedes and governs law The Mosaic law cannot annul the Abrahamic promise because the inheritance was granted by promise before the law was given.
- The law served a temporary custodial role The law exposed and imprisoned transgression until Christ came, functioning as guardian until justification by faith was revealed in its fullness.
- Faith in Christ creates sonship and inheritance All who are in Christ are children of God, clothed with Christ, one in Christ, Abraham's seed, and heirs according to the promise.
Paul rebukes the Galatians for turning from Spirit-begun faith to law-centered completion, proves from Abraham and Scripture that blessing comes by faith, shows that Christ redeemed believers from the law's curse, and declares that all who belong to Christ are sons and heirs according to the promise.
Paul argues that the Galatians' reception of the Spirit, Abraham's justification by faith, the curse attached to law-reliance, Christ's curse-bearing redemption, and the priority of the promise all prove that righteousness, blessing, sonship, and inheritance come through faith in Christ, not works of the law.
Theological logic
- The Galatians received the Spirit by believing the gospel, not by works of the law.
- If the Christian life began by the Spirit through faith, it cannot be completed by fleshly law-reliance.
- Abraham was counted righteous by faith, establishing the pattern for covenant blessing.
- Scripture foresaw Gentile justification by faith and preached the gospel beforehand to Abraham.
- Those who rely on works of the law are under a curse because the law demands complete obedience.
- The righteous live by faith, and the law is not based on faith as its operating principle for righteousness.
- Christ redeemed believers from the curse by becoming a curse for them.
- Christ's curse-bearing brings Abraham's blessing to the Gentiles and grants the promised Spirit through faith.
- The law, coming after the promise, cannot annul the promise or alter the inheritance's gracious basis.
- The law was added because of transgressions until the promised Seed came.
- Scripture imprisoned everything under sin so that the promise would be given through faith in Jesus Christ.
- The law functioned as guardian until Christ, but believers are no longer under that guardian now that faith has come.
- All who are in Christ are children of God, clothed with Christ, one in Christ, Abraham's seed, and heirs according to promise.
- Do not read Paul's argument as though the Old Testament law was evil or contrary to God's character; Paul explicitly denies that the law is against God's promises.
- Do not use the passage to erase the Abrahamic promise or detach it from Christ; Paul argues that the promise is fulfilled in the Seed, who is Christ.
- Do not treat the law's temporary guardianship as the permanent identity marker for believers after Christ has come.
- Do not conclude that faith makes holiness irrelevant; Paul's later argument will define freedom as Spirit-enabled love, not fleshly autonomy.
- Do not make the inheritance depend partly on promise and partly on law-performance; Paul insists that inheritance is not based on law if it is given by promise.
- Do not flatten the law's role into merely moral advice; in Paul's argument it has a covenantal, redemptive-historical function that exposes sin and guards until Christ.
- Do not read Paul as saying God’s law is sinful, false, or opposed to God’s promises; Paul explicitly denies that conclusion.
- Do not make the Abrahamic promise depend on Mosaic law-performance, since Paul’s argument rests on the promise’s priority and permanence.
- Do not flatten 'seed' into a merely generic plural category when Paul explicitly identifies the promised seed with Christ.
- Do not treat the law’s temporary custodial role as though it were the permanent structure of justification or inheritance for believers in Christ.
- Do not use Christian freedom to diminish holiness; Paul’s point is that holiness flows from promise, faith, and the Spirit rather than from law as the basis of justification.
- Believers must not allow obedience, spiritual disciplines, church participation, or moral seriousness to become the ground of acceptance before God.
- The law should be honored for its exposing and restraining function without being confused with the promise that grants inheritance.
- Churches must guard against teaching that subtly relocates confidence from Christ’s finished work to visible religious performance.
- Those burdened by guilt need the law’s diagnosis to drive them to Christ, not to self-salvation through intensified rule-keeping.
- Pastoral correction should preserve both the goodness of God’s commands and the sufficiency of God’s promise in Christ.
- Return regularly to the public proclamation of Christ crucified as the center of faith.
- Ask whether spiritual practices are being used as means of communion with God or as grounds of confidence before God.
- Teach believers to distinguish the law's exposing and guarding role from Christ's saving and fulfilling role.
- Use Galatians 3:13 to counsel guilty consciences toward Christ's curse-bearing redemption.
- Disciple Christians to live as children and heirs rather than religious contractors.
- Build church fellowship around union with Christ rather than cultural, ethnic, economic, or social status markers.
- Keep the promised Spirit central to Christian formation.
Humble, Spirit-dependent faith that rests in Christ, honors God's promise, refuses performance-righteousness, and receives fellow believers as one in Christ.
- Abraham justified by faith : Paul uses Genesis 15:6 to show that righteousness was credited to Abraham by faith, making faith central to the covenant promise before the Mosaic law.
- Blessing to the nations : The promise that all nations would be blessed through Abraham is interpreted as the advance announcement of Gentile justification by faith.
- The curse of the law : Paul draws from Deuteronomy to show that the law brings curse upon those who do not continue in all that it commands.
- The righteous live by faith : Habakkuk's declaration becomes a central biblical witness that life before God is by faith, not law-reliance.
- Christ hung on the tree : Paul applies Deuteronomy 21:23 to Christ's crucifixion, showing that Christ entered the place of curse to redeem His people.
- Promise and Seed : Paul identifies Christ as the Seed in whom the Abrahamic promise finds its focal fulfillment.
- Law as temporary guardian : The law's temporary custodial role fits the larger biblical movement from promise through law to fulfillment in Christ.
- One people in Christ : Galatians 3:28 aligns with the New Testament witness that Christ creates one people of God through union with Himself.
The gospel rests on God's gracious promise fulfilled in Christ, not on human achievement under the law. The law exposes the universal captivity of sin, but Christ the promised Seed brings the blessing, inheritance, and faith-reality promised beforehand. Believers therefore stand not as law-achievers trying to secure life, but as promise-receivers united to Christ by faith.
