Galatians 3:21-24

Verse 21. Is the law then against the promises of God? Is the law of Moses to be regarded as opposed to the promises made to Abraham? Does this follow from any view which can be taken of the subject? The object of the apostle in asking this question is, evidently, to take an opportunity to deny, in the most positive manner, that there can be any such clashing or contradiction. He shows, therefore, what was the design of the law, and declares that the object was to further the plan contemplated in the promise made to Abraham. It was an auxiliary to that. It was as good as a law could be; and it was designed to prepare the way for the fulfillment of the promise made to Abraham.

God forbid. It cannot be. It is impossible. I do not hold such an opinion. Such a sentiment by no means follows from what has been advanced. Comp. Rom 3:4.

For if there had been a law given which could have given life. The law of Moses is as good as a law can be. It is pure, and holy, and good. It is not the design to insinuate anything against the law in itself, or to say that as a law it is defective. But law could not give life. It is not its nature; and man cannot be justified by obedience to it. No man ever has yielded perfect compliance with it, and no man, therefore, can be justified by it. Gal 2:16, Gal 3:10.

Verily righteousness should have been by the law. Or justification would have been secured by the law. The law of Moses was as well adapted to this as a law could be. No better law could have been originated for this purpose; and if men were to attempt to justify themselves before God by their own works, the law of Moses would be as favourable for such an undertaking as any law which could be revealed. It is as reasonable, and equal, and pure. Its demands are as just, and its terms as favourable, as could be any of the terms of mere law. And such a law has been given, in part, in order to show that. justification by the law is out of the question. If men could not be justified by a law so pure, and equal, and just, so reasonable in all its requirements, and so perfect, how could they expect to be justified by conformity to any inferior or less perfect rule of life? The fact, therefore, that no one can be justified by the pure law revealed on Mount Sinai, for ever settles the question about the possibility of being justified by law.

(a) "against the promises" Mt 5:17 (b) "if there had been" Gal 2:21
Verse 22. But the Scripture. The Old Testament, Jn 5:39, containing the law of Moses.

Hath concluded all under sin. Has shut up συνεκλεισεν all under the condemnation of sin; that is, has declared all men, no matter what their rank and external character, to be sinners. Of course, they cannot be justified by that law which declares them to be guilty, and which condemns them, any more than the law of the land will acquit a murderer, and pronounce him innocent, at the same time that it holds him to be guilty. In regard to the meaning of the expression here used, Rom 11:32. Comp. Rom 3:9,19.

That the promise by faith of Jesus Christ, etc. That the promise referred to in the transaction with Abraham, the promise of justification and life by faith in the Messiah. Here we see one design of the law. It was to show that they could not be justified by their own works, to hedge up their way in regard to justification by their own righteousness, and to show them their need of a better righteousness. The law accomplishes the same end now. It shows men that they are guilty; and it does it in order that they may be brought under the influence of the pure system of the gospel, and become interested in the promises which are connected with eternal salvation.

(c) "all under sin" Rom 3:19,19,23 (d) "promise by faith" Rom 4:11,12,16
Verse 23. But before faith came. That is, the system of salvation by faith in the Lord Jesus. Faith here denotes the Christian religion, because faith is its distinguishing characteristic.

We were kept under the law. We, who were sinners; we, who have violated the law. It is a general truth, that before the gospel was introduced, men were under the condemning sentence of the law.

Shut up unto the faith. Enclosed by the law with reference to the full and glorious revelation of a system of salvation by faith. The design and tendency of the law was to shut us up to that as the only method of salvation. All other means failed. The law condemned every other mode, and the law condemned all who attempted to be justified in any other way. Man, therefore, was shut up to that as his last hope; and could look only to that for any possible prospect of salvation. The word which in this verse is rendered "were kept," εφρουρουμεθα, usually means to guard or watch, as in a castle, or as prisoners are guarded; and though the word should not be pressed too far in the interpretation, yet it implies that there was a rigid scrutiny observed; that the law guarded: them; that there was no way of escape; and that they were shut up, as prisoners under sentence of death, to the only hope, which was that of pardon.
Verse 24. Wherefore the law was our schoolmaster. The word rendered schoolmaster, παιδαγωγος, whence the word pedagogue, referred originally to a slave or freedman, to whose care boys were committed, and who accompanied them to the public schools. The idea here is not that, of instructor, but there is reference to the office and duty of the paedagogus among the ancients. The office was usually intrusted to slaves or freedmen. It is true, that when the paedagogus was properly qualified, he assisted the children committed to his care in preparing their lessons. But still his main duty was not instruction, but it was to watch over the boys; to restrain them from evil and temptation; and to conduct them to the schools, where they might receive instruction. See, for illustrations of this, Wetstein, Bloomfield, etc. In the passage before us, the proper notion of pedagogue is retained. In our sense of the word schoolmaster, Christ is the schoolmaster, and not the law. The law performs the office of the ancient pedagogue, to lead us to the teacher or the instructor. That teacher or instructor is Christ. The ways in which the law does this may be the following:

(1.) It restrains us and rebukes us, and keeps us as the ancient pedagogue did his boys.

(2.) The whole law was designed to be introductory to Christ. The sacrifices and offerings were designed to shadow forth the Messiah, and to introduce him to the world.

(3.) The moral law--the law of God--shows men their sin and danger, and thus leads them to the Saviour. It condemns them, and thus prepares them to welcome the offer of pardon through a Redeemer.

(4.) It still does this. The whole economy of the Jews was designed to do this; and under the preaching of the gospel it is still done. Men see that they are condemned; they are convinced by the law that they cannot save themselves, and thus they are led to the Redeemer. The effect of the preached gospel is to showy men their sins, and thus to be preparatory, to the embracing of the offer of pardon. Hence the importance of preaching the law still; and hence it is needful that men should be made to feel that they are sinners, in order that they may be prepared to embrace the offers of mercy. Comp. Rom 10:4.
