The apostle is here dealing with those who, having embraced the faith of Christ, still continued to seek for justification by the works of the law; that is, who depended upon their own obedience to the moral precepts as their righteousness before God, and, wherein that was defective, had recourse to the legal sacrifices and purifications to make it up. These he first sharply reproves, and then endeavours, by the evidence of truth, to convince them. This is the right method, when we reprove any for a fault or an error, to convince them that it is an error, that it is a fault.

He reproves them, and the reproof is very close and warm: he calls them foolish Galatians, Gal 3:1. Though as Christians they were Wisdom's children, yet as corrupt Christians they were foolish children. Yea, he asks, Who hath bewitched you? whereby he represents them as enchanted by the arts and snares of their seducing teachers, and so far deluded as to act very unlike themselves. That wherein their folly and infatuation appeared was that they did not obey the truth; that is, they did not adhere to the gospel way of justification, wherein they had been taught, and which they had professed to embrace. Note, It is not enough to know the truth, and to say we believe it, but we must obey it too; we must heartily submit to it, and stedfastly abide by it. Note, also, Those are spiritually bewitched who, when the truth as it is in Jesus is plainly set before them, will not thus obey it. Several things proved and aggravated the folly of these Christians.

1.Jesus Christ had been evidently set forth as crucified among them; that is, they had had the doctrine of the cross preached to them, and the sacrament of the Lord's supper administered among them, in both which Christ crucified had been set before them. Now, it was the greatest madness that could be for those who had acquaintance with such sacred mysteries, and admittance to such great solemnities, not to obey the truth which was thus published to them, and signed and sealed in that ordinance. Note, The consideration of the honours and privileges we have been admitted to as Christians should shame us out of the folly of apostasy and backsliding.

2.He appeals to the experiences they had had of the working of the Spirit upon their souls (Gal 3:2); he puts them in mind that, upon their becoming Christians, they had received the Spirit, that many of them at least had been made partakers not only of the sanctifying influences, but of the miraculous gifts, of the Holy Spirit, which were eminent proofs of the truth of the Christian religion and the several doctrines of it, and especially of this, that justification is by Christ only, and not by the works of the law, which was one of the peculiar and fundamental principles of it. To convince them of the folly of their departing from this doctrine, he desires to know how they came by these gifts and graces: Was it by the works of the law, that is, the preaching of the necessity of these in order to justification? This they could not say, for that doctrine had not then been preached to them, nor had they, as Gentiles, any pretence to justification in that way. Or was it by the hearing of faith, that is, the preaching of the doctrine of faith in Christ as the only way of justification? This, if they would say the truth, they were obliged to own, and therefore must be very unreasonable if they should reject a doctrine of the good effects of which they had had such experience. Note, (1.) It is usually by the ministry of the gospel that the Spirit is communicated to persons. And, (2.) Those are very unwise who suffer themselves to be turned away from the ministry and doctrine which have been blessed to their spiritual advantage.

3.He calls upon them to consider their past and present conduct, and thence to judge whether they were not acting very weakly and unreasonably (Gal 3:3, Gal 3:4): he tells them that they had begun in the Spirit, but now were seeking to be made perfect by the flesh; they had embraced the doctrine of the gospel, by means of which they had received the Spirit, and wherein only the true way of justification is revealed. And thus they had begun well; but now they were turning to the law, and expected to be advanced to higher degrees of perfection by adding the observance of it to faith in Christ, in order to their justification, which could end in nothing but their shame and disappointment: for this, instead of being an improvement upon the gospel, was really a perversion of it; and, while they sought to be justified in this way, they were so far from being more perfect Christians that they were more in danger of becoming no Christians at all; hereby they were pulling down with one hand what they had built with the other, and undoing what they had hitherto done in Christianity. Yea, he further puts them in mind that they had not only embraced the Christian doctrine, but suffered for it too; and therefore their folly would be the more aggravated, if now they should desert it: for in this case all that they had suffered would be in vain - it would appear that they had been foolish in suffering for what they now deserted, and their sufferings would be altogether in vain, and of no advantage to them. Note, (1.) It is the folly of apostates that they lose the benefit of all they have done in religion, or suffered for it. And, (2.) It is very sad for any to live in an age of services and sufferings, of sabbaths, sermons, and sacraments, in vain; in this case former righteousness shall not be mentioned.

4.He puts them in mind that they had had ministers among them (and particularly himself) who came with a divine seal and commission; for they had ministered the Spirit to them, and wrought miracles among them: and he appeals to them whether they did it by the works of the law or by the hearing of faith, whether the doctrine that was preached by them, and confirmed by the miraculous gifts and operations of the Spirit, was that of justification by the works of the law or by the faith of Christ; they very well knew that it was not the former, but the latter; and therefore must needs be inexcusable in forsaking a doctrine which had been so signally owned and attested, and exchanging it for one that had received no such attestations.

Have ye suffered so many things in vain? - Have ye received and lost so much good? The verb πασχων, as compounded with ευ, well, or κακως, ill, and often without either, signifies to suffer pain or loss, or to possess and enjoy. In such a case the man is considered as the patient, and the good or ill acts upon him. Though it is possible that the Galatians had suffered some persecution for the truth of Christ, yet it is as likely that the apostle refers to the benefits which they had received. Ye have received faith, the pardon of your sins, the gift of the Holy Spirit, and with it many extraordinary gifts and graces; and have ye suffered the loss of all these things? Have ye received all these in vain? if yet in vain - if it be credible that ye have sacrificed so many excellent benefits for an imaginary good.

Have ye suffered so many things in vain?.... These Galatians had suffered great reproach, many afflictions and persecutions for the sake of the Gospel, as all that embrace it must expect to do; and which to them that persevere in the faith of the Gospel will not be in vain, they will be followed with eternal life and glory; not that these things are meritorious of such happiness, or deserve such a reward; the reward of them is not of debt, but of grace. But, if such who have made a profession, and have suffered for it, should after all relinquish it, their sufferings for it are in vain; they will come short of that glory which is promised to them that suffer for righteousness sake: and this is another aggravation of the folly of these persons, that they should suffer so much persecution for the Gospel, which, if not true, they must have suffered in vain, and might as well have avoided it; and, if true, by relinquishing it not only sustain a great loss, but bring great hurt and damage to themselves:

if it be yet in vain; by which words the apostle does, as it were, correct himself, and expresses his hope of them, that they would see their mistake, revoke their error, and abide by the truth of the Gospel.

Have ye suffered so many things--namely, persecution from Jews and from unbelieving fellow countrymen, incited by the Jews, at the time of your conversion.

in vain--fruitlessly, needlessly, since ye might have avoided them by professing Judaism [GROTIUS]. Or, shall ye, by falling from grace, lose the reward promised for all your sufferings, so that they shall be "in vain" (Gal 4:11; Co1 15:2, Co1 15:17-19, Co1 15:29-32; Th2 1:5-7; Jo2 1:8)?

yet--rather, "If it be really (or 'indeed') in vain" [ELLICOTT]. "If, as it must be, what I have said, 'in vain,' is really the fact" [ALFORD]. I prefer understanding it as a mitigation of the preceding words. I hope better things of you, for I trust you will return from legalism to grace; if so, as I confidently expect, you will not have "suffered so many things in vain" [ESTIUS]. For "God has given you the Spirit and has wrought mighty works among you" (Gal 3:5; Heb 10:32-36) [BENGEL].
