31 Oh, foolish Galatians! Who has cast an evil spell on you? For the meaning of Jesus Christ's death was made as clear to you as if you had seen a picture of his death on the cross. 2 Let me ask you this one question: Did you receive the Holy Spirit by obeying the law of Moses? Of course not! You received the Spirit because you believed the message you heard about Christ. 3 How foolish can you be? After starting your new lives in the Spirit, why are you now trying to become perfect by your own human effort?
Matthew Henry's Commentary on Galatians 3:1-3
Commentary on Galatians 3:1-5
(Read Galatians 3:1-5)
Several things made the folly of the Galatian Christians worse. They had the doctrine of the cross preached, and the Lord's supper administered among them, in both which Christ crucified, and the nature of his sufferings, had been fully and clearly set forth. Had they been made partakers of the Holy Spirit, by the ministration of the law, or on account of any works done by them in obedience thereto? Was it not by their hearing and embracing the doctrine of faith in Christ alone for justification? Which of these had God owned with tokens of his favour and acceptance? It was not by the first, but the last. And those must be very unwise, who suffer themselves to be turned away from the ministry and doctrine which have been blessed to their spiritual advantage. Alas, that men should turn from the all-important doctrine of Christ crucified, to listen to useless distinctions, mere moral preaching, or wild fancies! The god of this world, by various men and means, has blinded men's eyes, lest they should learn to trust in a crucified Saviour. We may boldly demand where the fruits of the Holy Spirit are most evidently brought forth? whether among those who preach justification by the works of the law, or those who preach the doctrine of faith? Assuredly among the latter.
