Galater 3:25

"But now that faith is come," &c. Moses the lawgiver cannot bring us into the heavenly Canaan though he can bring us to the border of it. At that point he is superseded by Joshua, the type of Jesus, who leads the true Israel into their inheritance. The law leads us to Christ, and there its office ceases.

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.

3:25 the way of faith has come: The principle of righteousness by faith was always operative (cp. 3:6-9), but the object of that faith and the means of appropriating it are now clear to everyone through Jesus Christ. • we no longer need the law as our guardian: In Greco-Roman culture, a freeborn child who came of age was no longer under the discipline of a guardian, but was free to rule himself. So, too, those who are “of age” through faith in Christ are free from the guardianship of the law. They serve Christ directly as he leads by his word and Spirit.
