3:22 But the {s} scripture hath concluded {t} all under sin, that the {u} promise by faith of Jesus Christ might be given to them that believe.
(s) By this word scripture he means the Law.
(t) All mankind, and whatever comes from mankind.
(u) In every one of these words, there lies an argument against the merits of works: for all these words, promise, faith, Christ, might be given, to believers, are against meritorious works, and not one of them can be included as a meritorious work.
3:22 But the scripture hath concluded all under sin. But none became righteous by the law. The Scriptures place all under sin that the promise should be to them only who believe through Christ.
The promise by faith of Jesus Christ might be given to them that believe. All hope is in the gospel. See Ro 11:32.
3:22 But, on the contrary, the scripture wherein that law is written hath concluded all under sin - Hath shut them up together, (so the word properly signifies,) as in a prison, under sentence of death, to the end that all being cut off from expecting justification by the law, the promise might be freely given to them that believe.
3:19-22 If that promise was enough for salvation, wherefore then serveth the law? The Israelites, though chosen to be God's peculiar people, were sinners as well as others. The law was not intended to discover a way of justification, different from that made known by the promise, but to lead men to see their need of the promise, by showing the sinfulness of sin, and to point to Christ, through whom alone they could be pardoned and justified. The promise was given by God himself; the law was given by the ministry of angels, and the hand of a mediator, even Moses. Hence the law could not be designed to set aside the promise. A mediator, as the very term signifies, is a friend that comes between two parties, and is not to act merely with and for one of them. The great design of the law was, that the promise by faith of Jesus Christ, might be given to those that believe; that, being convinced of their guilt, and the insufficiency of the law to effect a righteousness for them, they might be persuaded to believe on Christ, and so obtain the benefit of the promise. And it is not possible that the holy, just, and good law of God, the standard of duty to all, should be contrary to the gospel of Christ. It tends every way to promote it.
