I do not frustrate the grace of God - The word rendered "frustrate" (ἀθετῶ athetō) means properly to displace, abrogate, abolish; then to make void, to render null; Mark 7:9; Luke 7:30; 1 Corinthians 1:19. The phrase "the grace of God," here refers to the favor of God manifested in the plan of salvation by the gospel, and is another name for the gospel. The sense is, that Paul would not take any measures or pursue any course that would render that vain or inefficacious. Neither by his own life, by a course of conduct which would show that it had no influence over the heart and conduct, nor by the observance of Jewish rites and customs, would he do anything to render that inefficacious. The design is to show that he regarded it as a great principle that the gospel was efficacious in renewing and saving man, and he would do nothing that would tend to prevent that impression on mankind. A life of sin, of open depravity and licentiousness, would do that. And in like manner a conformity to the rites of Moses as a ground of justification would tend to frustrate the grace of God, or to render the method of salvation solely by the Redeemer nugatory. This is to be regarded, therefore as at the same time a reproof of Peter for complying with customs which tended to frustrate the plan of the gospel, and a declaration that he intended that his own course of life should be such as to confirm the plan, and show its efficacy in pardoning the sinner and rendering him alive in the service of God.

For if righteousness come by the law - If justification can be secured by the observance of any law - ceremonial or moral - then there was no need of the death of Christ as an atonement. This is plain. If man by conformity to any law could be justified before God, what need was there of an atonement? The work would then have been wholly in his own power, and the merit would have been his. It follows from this, that man cannot be justified by his own morality, or his alms-deeds, or his forms of religion, or his honesty and integrity. If he can, he needs no Saviour; he can save himself. It follows also that when people depend on their own amiableness, and morality, and good works, they would feel no need of a Saviour; and this is the true reason why the mass of people reject the Lord Jesus. They suppose they do not deserve to be sent to hell. They have no deep sense of guilt. They confide in their own integrity, and feel that God ought to save them. Hence, they feel no need of a Saviour; for why should a person in health employ a physician? And confiding in their own righteousness, they reject the grace of God, and despise the plan of justification through the Redeemer. To feel the need of a Saviour it is necessary to feel that we are lost and ruined sinners; that we have no merit upon which we can rely; and that we are entirely dependent on the mercy of God for salvation. Thus feeling, we shall receive the salvation of the gospel with thankfulness and joy, and show that in regard to us Christ is not "dead in vain."

I do not frustrate - Ουκ αθετω· I do not contemn, despise, or render useless, the grace of God - the doctrine of Christ crucified; which I must do if I preach the necessity of observing the law.

For if righteousness - If justification and salvation come by an observance of the law, then Christ is dead in vain; his death is useless if an observance of the law can save us; but no observance of the law can save us, and therefore there was an absolute necessity for the death of Christ.

1. The account of the prevarication of Peter in the preceding chapter teaches us a most useful lesson. Let him who assuredly standeth take heed lest he fall. No person in a state of probation is infallible; a man may fall into sin every moment; and he will, if he do not walk with God. Worldly prudence and fleshly wisdom would have concealed this account of the prevarication of Peter; but God tells truth. This the fountain of it; and from him we are to expect not only nothing but the truth, but also the whole truth. If the Gospel were not of God we had never heard of the denial and prevarication of Peter, nor of the contention between Paul and Barnabas. And these accounts are recorded, not that men may justify or excuse their own delinquencies by them, but that they may avoid them; for he must be inexcusable who, with these histories before his eyes, ever denies his Master, or acts the part of a hypocrite. Had the apostles acted in concert to impose a forgery on the world as a Divine revelation, the imposture would have now come out. The falling out of the parties would have led to a discovery of the cheat. This relation, therefore, is an additional evidence of the truth of the Gospel.

2. On, I through the law am dead to the law, etc., pious Quesnel makes the following useful reflections:

"The ceremonial law, which is no more than a type and shadow of him, destroys itself by showing us Jesus Christ, who is the truth and the substance. The moral law, by leaving us under our own inability under sin and the curse, makes us perceive the necessity of the law of the heart, and of a Savior to give it. The law is for the old man, as to its terrible and servile part; and it was crucified and died with Christ upon the cross as well as the old man. The new man, and the new law, require a new sacrifice. What need has he of other sacrifices who has Jesus Christ? They in whom this sacrifice lives, do themselves live to God alone; but none can live to him except by faith; and this life of faith consists in dying with Christ to the things of the present world, and in expecting, as co-heirs with him, the blessings of the eternal world. And who can work all this in us but only he who lives in us? That man has arrived to a high degree of mortification, who can say Christ liveth in me, and I am crucified to the world. Such a one must have renounced not only earthly things, but his own self also."

3. Is there, or can there be, any well grounded hope of eternal life but what comes through the Gospel? In vain has the ingenuity of man tortured itself for more than 5000 years, to find out some method of mending the human heart: none has been discovered that even promised any thing likely to be effectual. The Gospel of Christ not only mends but completely cures and new makes infected nature. Who is duly apprised of the infinite excellency and importance of the Gospel? What was the world before its appearance? What would it be were this light extinguished? Blessed Lord! let neither infidelity nor false doctrine rise up to obscure this heavenly splendor!

I do not frustrate the grace of God,.... Or "cast it away", as the Vulgate Latin version reads it; or "deny it", as the Syriac and Arabic; or "despise, reject, and make it void", as other versions; meaning either the grace of the Son of God in giving himself for him, just mentioned by him; or the particular doctrine of grace, justification, he is speaking of, as proceeding from the grace of God, upon the foot of the righteousness of Christ; or the whole Gospel, all and each of which would be denied, despised, rejected, made null and void, be in vain, fallen and departed from, should justification be sought for by the works of the law: but this the apostle did not do, and therefore did not frustrate the grace of God: which to do would be to act the most ungenerous and ungrateful part to God, and Christ, and to that love and grace which are so largely displayed in the free justification of a sinner.

For if righteousness come by the law; if a justifying righteousness is to be attained unto by the works of the law, or men can be justified by their obedience to it,

then Christ is dead in vain; there was no necessity for his dying: he died without any true reason, or just cause; he died to bring in a righteousness which might have been brought in without his death, and so his blood and life might have been spared, his sufferings and death being entirely unnecessary; which to say is to cast contempt upon the wisdom, love, and grace of God in this matter, and to offer the greatest indignity to the person, character, sufferings, and death of Christ. Wherefore it may be strongly concluded, that there is no righteousness by the law of works, nor to be attained that way, otherwise Christ had never died; and that justification is solely and alone by his righteousness.

Frustrate (ἀθετῶ)

Annul or invalidate. Comp. Mark 7:9; 1 Corinthians 1:19; Galatians 3:15.

The grace of God (τὴν χάριν τοῦ θεοῦ)

Χάρις is, primarily, that which gives joy (χαρά). Its higher, Christian meaning is based on the emphasis of freeness in a gift or favor. It is the free, spontaneous, absolute loving kindness of God toward men. Hence often in contrast with the ideas of debt, law, works, sin. Sometimes for the gift of grace, the benefaction, as 1 Corinthians 16:3; 2 Corinthians 8:6, 2 Corinthians 8:19; 1 Peter 1:10, 1 Peter 1:13. So here: the gracious gift of God in the offering of Christ.

Is dead (ἀπέθανεν)

More correctly, died; pointing to the historical incident.

In vain (δωρεὰν)

Groundlessly, without cause. See on 2 Thessalonians 3:8. The sense here is not common. It is not found in Class., and in N.T. only John 15:25. In lxx, see Psalm 34:7, 19; 108:3; 118:161; 1 Samuel 19:5; Sir. 20:23; 29:6. Comp. Ignatius, Trall. v. Paul says: "I do not invalidate the grace of God in the offering of Christ, as one does who seeks to reestablish the law as a means of justification; for if righteousness comes through the law, there was no occasion for Christ to die."

Additional Note on Galatians 2:14-21.

The course of thought in Paul's address to Peter is difficult to follow. It will help to simplify it if the reader will keep it before him that the whole passage is to be interpreted in the light of Peter's false attitude - as a remonstrance against a particular state of things.

The line of remonstrance is as follows. If you, Peter, being a Jew, do not live as a Jew, but as a Gentile, as you did when you ate with Gentiles, why do you, by your example in withdrawing from Gentile tables, constrain Gentile Christians to live as Jews, observing the separative ordinances of the Jewish law? This course is plainly inconsistent.

Even you and I, born Jews, and not Gentiles - sinners - denied the obligation of these ordinances by the act of believing on Jesus Christ. In professing this faith we committed ourselves to the principle that no one can be justified by the works of the law.

But it may be said that we were in no better case by thus abandoning the law and legal righteousness, since, in the very effort to be justified through Christ, we were shown to be sinners, and therefore in the same category with the Gentiles. Does it not then follow that Christ is proved to be a minister of sin in requiring us to abandon the law as a means of justification?

No. God forbid. It is true that, in seeking to be justified in Christ, we stood revealed as sinners, for it was Christ who showed us that we could not be justified by the works of the law; that all our legal strictness only left us sinners. But the inference is false that Christ is thereby shown to be a minister of sin.

{5} I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead {e} in vain.

(5) The second argument taken from an absurdity: if men may be justified by the Law, then it was not necessary for Christ to die.

(e) For there was no reason why he should do so.

2:21 I do not frustrate the grace of God. Make void, in the Revised Version. He would do so, if he went back to the Jewish law, and trusted in it. If it gave righteousness, then the gospel was not needed, and Christ died in vain.

NOTE.--The account in this chapter of Paul's visit to Jerusalem, and of his controversy with Peter, is utterly inconsistent with the Romish doctrine of the supremacy of Peter. No Pope could or would allow a bishop or cardinal to rebuke him openly, as Paul did Peter. So, too, the reference of the controversy in Acts 15, to the apostles and elders (Ac 15:6), instead of to Peter, and the final judgment of James, which was received, contradict the Vatican system. Indeed, the doctrine of popedom is utterly inconsistent with the whole tenor of the Acts, and the Pauline Epistles. This meeting at Antioch is the last between Peter and Paul of which the New Testament gives record. Early church tradition, however, reports that they met once in Rome, where they were tried and condemned on the same day, and then parted, Peter to be crucified on the hill of the Janiculum, and Paul, the Roman citizen, to be beheaded at the Three Fountains on the Ostian Way. Could we rely upon this tradition it would seem fitting that the two greatest apostles, of the Circumcision and of the Uncircumcision, should lay down their burdens together and go side by side to report their work to their common Lord.

2:21 Meantime I do not make void - In seeking to be justified by my own works. The grace of God - The free love of God in Christ Jesus. But they do, who seek justification by the law. For if righteousness is by the law - If men might be justified by their obedience to the law, moral or ceremonial. Then Christ died in vain - Without any necessity for it, since men might have been saved without his death; might by their own obedience have been both discharged from condemnation, and entitled to eternal life.

Margin grace

Grace (in salvation). vs. Gal 5:4 Rom 3:24. See Scofield Note: "Jn 1:17".

Margin righteousness

See Scofield Note: "Rom 10:10".

21. I do not frustrate the grace of God-I do not make it void, as thou, Peter, art doing by Judaizing.

for-justifying the strong expression "frustrate," or "make void."

is dead in vain-Greek, "Christ died needlessly," or "without just cause." Christ's having died, shows that the law has no power to justify us; for if the law can justify or make us righteous, the death of Christ is superfluous [Chrysostom].

2:20,21 Here, in his own person, the apostle describes the spiritual or hidden life of a believer. The old man is crucified, Ro 6:6, but the new man is living; sin is mortified, and grace is quickened. He has the comforts and the triumphs of grace; yet that grace is not from himself, but from another. Believers see themselves living in a state of dependence on Christ. Hence it is, that though he lives in the flesh, yet he does not live after the flesh. Those who have true faith, live by that faith; and faith fastens upon Christ's giving himself for us. He loved me, and gave himself for me. As if the apostle said, The Lord saw me fleeing from him more and more. Such wickedness, error, and ignorance were in my will and understanding, that it was not possible for me to be ransomed by any other means than by such a price. Consider well this price. Here notice the false faith of many. And their profession is accordingly; they have the form of godliness without the power of it. They think they believe the articles of faith aright, but they are deceived. For to believe in Christ crucified, is not only to believe that he was crucified, but also to believe that I am crucified with him. And this is to know Christ crucified. Hence we learn what is the nature of grace. God's grace cannot stand with man's merit. Grace is no grace unless it is freely given every way. The more simply the believer relies on Christ for every thing, the more devotedly does he walk before Him in all his ordinances and commandments. Christ lives and reigns in him, and he lives here on earth by faith in the Son of God, which works by love, causes obedience, and changes into his holy image. Thus he neither abuses the grace of God, nor makes it in vain.
