Galatians 3:2

"Was it by the works of the law that ye received the Spirit (manifested by outward miracles, Gal 3:5; Mar 16:17; Heb 2:4; and by spiritual graces, Gal 3:14; Gal 4:5-6; Eph 1:13), or by the hearing of faith?" The "only" implies, "I desire, omitting other arguments, to rest the question on this alone"; I who was your teacher, desire now to "learn" this one thing from you. The epithet "Holy" is not prefixed to "Spirit" because that epithet is a joyous one, whereas this Epistle is stern and reproving [BENGEL]. hearing of faith--Faith consists not in working, but in receiving (Rom 10:16-17).

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.

3:2 The Galatians, like all Christians, received the Spirit by faith in Christ, not by obeying the law of Moses (see Acts 2:38-39; Rom 8:9-11; 2 Cor 1:22; Eph 1:11-14; cp. Acts 10:44-48; 11:15-18). God accepted the Galatians because of their faith in the message . . . about Christ (cp. Rom 10:14-17), which made their turning to the law absurd (Gal 3:3-4).
