Galatians 3:22

But--as the law cannot give life or righteousness [ALFORD]. Or the "But" means, So far is righteousness from being of the law, that the knowledge of sin is rather what comes of the law [BENGEL]. the scripture--which began to be written after the time of the promise, at the time when the law was given. The written letter was needed SO as PERMANENTLY to convict man of disobedience to God's command. Therefore he says, "the Scripture," not the "Law." Compare Gal 3:8, "Scripture," for "the God of the Scripture." concluded--"shut up," under condemnation, as in a prison. Compare Isa 24:22, "As prisoners gathered in the pit and shut up in the prison." Beautifully contrasted with "the liberty wherewith Christ makes free," which follows, Gal 3:7, Gal 3:9, Gal 3:25-26; Gal 5:1; Isa 61:1. all--Greek neuter, "the universe of things": the whole world, man, and all that appertains to him. under sin-- (Rom 3:9, Rom 3:19; Rom 11:32). the promise--the inheritance promised (Gal 3:18). by faith of Jesus Christ--that is which is by faith in Jesus Christ. might be given--The emphasis is on "given": that it might be a free gift; not something earned by the works of the law (Rom 6:23). to them that believe--to them that have "the faith of (in) Jesus Christ" just spoken of.

The apostle in this chapter, I. Reproves the Galatians for their folly, in suffering themselves to be drawn away from the faith of the gospel, and endeavours, from several considerations, to impress them with a sense of it. II. He proves the doctrine which he had reproved them for departing from - that of justification by faith without the works of the law, 1. From the example of Abraham's justification. 2. From the nature and tenour of the law. 3. From the express testimony of the Old Testament; and, 4. From the stability of the covenant of God with Abraham. Lest any should hereupon say, "Wherefore then serveth the law?" he answers, (1.) It was added because of transgressions. (2.) It was given to convince the world of the necessity of a Saviour. (3.) It was designed as a schoolmaster, to bring us to Christ. And then he concludes the chapter by acquainting us with the privilege of Christians under the gospel state.

3:22 we are all prisoners of sin: See Rom 3:9; 7:1-13; 11:32. Keeping the law is of no use in bringing salvation; only believing in Jesus Christ can bring freedom.
