That these Christians might be the more ashamed of their defection from the truth of the gospel which Paul had preached to them, he here reminds them of the great affection they formerly had for him and his ministry, and puts them upon considering how very unsuitable their present behaviour was to what they then professed. And here we may observe,

I.How affectionately he addresses himself to them. He styles them brethren, though he knew their hearts were in a great measure alienated from him. He desires that all resentments might be laid aside, and that they would bear the same temper of mind towards him which he did to them; he would have them to be as he was, for he was as they were, and moreover tells them that they had not injured him at all. He had no quarrel with them upon his own account. Though, in blaming their conduct, he had expressed himself with some warmth and concern of mind he assured them that it was not owing to any sense of personal injury or affront (as they might be ready to think), but proceeded wholly from a zeal for the truth and purity of the gospel, and their welfare and happiness. Thus he endeavours to mollify their spirits towards him, that so they might be the better disposed to receive the admonitions he was giving them. Hereby he teaches us that in reproving others we should take care to convince them that our reproofs do not proceed from any private pique or resentment, but from a sincere regard to the honour of God and religion and their truest welfare; for they are then likely to be most successful when they appear to be most disinterested.

II.How he magnifies their former affection to him, that hereby they might be the more ashamed of their present behaviour towards him. To this purpose, 1. He puts them in mind of the difficulty under which he laboured when he came first among them: I knew, says he, how, through infirmity of the flesh, I preached the gospel unto you at the first. What this infirmity of the flesh was, which in the following words he expresses by his temptation that was in his flesh (though, no doubt, it was well known to those Christians to whom he wrote), we can now have no certain knowledge of: some take it to have been the persecutions which he suffered for the gospel's sake; others, to have been something in his person, or manner of speaking, which might render his ministry less grateful and acceptable, referring to Co2 10:10, and to Co2 12:7-10. But, whatever it was, it seems it made no impression on them to his disadvantage. For, 2. He takes notice that, notwithstanding this his infirmity (which might possibly lessen him in the esteem of some others), they did not despise nor reject him on the account of it, but, on the contrary, received him as an angel of God, even as Christ Jesus. They showed a great deal of respect to him, he was a welcome messenger to them, even as though an angel of God or Jesus Christ himself had preached to them; yea, so great was their esteem of him, that, if it would have been any advantage to him, they could have plucked out their own eyes, and have given them to him. Note, How uncertain the respects of people are, how apt they are to change their minds, and how easily they are drawn into contempt of those for whom they once had the greatest esteem and affection, so that they are ready to pluck out the eyes of those for whom they would before have plucked out their own! We should therefore labour to be accepted of God, for it is a small thing to be judged of man's judgment, Co1 4:3.

III.How earnestly he expostulates with them hereupon: Where is then, says he, the blessedness you spoke of? As if he had said, "Time was when you expressed the greatest joy and satisfaction in the glad tidings of the gospel, and were very forward in pouring out your blessings upon me as the publisher of them; whence is it that you are now so much altered, that you have so little relish of them or respect for me? You once thought yourselves happy in receiving the gospel; have you now any reason to think otherwise?" Note, Those who have left their first love would do well to consider, Where is now the blessedness they once spoke of? What has become of that pleasure they used to take in communion with God, and in the company of his servants? The more to impress upon them a just shame of their present conduct, he again asks (Gal 4:16), "Am I become your enemy, because I tell you the truth? How is it that I, who was heretofore your favourite, am now accounted your enemy? Can you pretend any other reason for it than that I have told you the truth, endeavoured to acquaint you with, and to confirm you in, the truth of the gospel? And, if not, how unreasonable must your disaffection be!" Note, 1. It is no uncommon thing for men to account those their enemies who are really their best friends; for so, undoubtedly, those are, whether ministers or others, who tell them the truth, and deal freely and faithfully with them in matters relating to their eternal salvation, as the apostle now did with these Christians. 2. Ministers may sometimes create enemies to themselves by the faithful discharge of their duty; for this was the case of Paul, he was accounted their enemy for telling them the truth. 3. Yet ministers must not forbear speaking the truth, for fear of offending others and drawing their displeasure upon them. 4. They may be easy in their own minds, when they are conscious to themselves that, if others have become their enemies, it is only for telling them the truth.

Am I therefore become your enemy - How is it that you are so much altered towards me, that you now treat me as an enemy, who formerly loved me with the most fervent affection? Is it because I tell you the truth; that very truth for which you at first so ardently loved me?

They zealously affect you,.... Or "are jealous of you"; meaning the false apostles, whose names, in contempt, he mentions not, being unworthy to be taken notice of, and their names to be transmitted to posterity. These were jealous of them, not with a godly jealousy, as the apostle was, lest their minds should be corrupted from the simplicity of the Gospel; but they were jealous, lest they should love the apostle more than they, and therefore represented him in a very bad light, and expressed great love and kindness for them themselves:

but not well; their zeal and affection were not hearty, and sincere, and without dissimulation, but were all feigned, were only in word and in tongue, not in deed, and in truth: this zealous affection neither proceeded from right principles, nor with right views; they sought themselves, and their own carnal worldly interest, their own pleasure and profit, and not the good and welfare of the souls of these Galatians:

yea, they would exclude you; that is, either from the apostle, from bearing any love unto, and having any respect for him. What they were wishing and seeking for was to draw off the minds and affections of these persons from him; or they were desirous of removing them from the Gospel of Christ unto another Gospel, and did all they could to hinder them from obeying the truth; and particularly were for shutting them out of their Christian liberty, and bringing them under the bondage of the law; yea, were for separating them from the churches, that they might set up themselves at the head of them. Some copies read "us", instead of "you"; and then the meaning is, that they were desirous of excluding the apostle from their company, and from having any share in their affections, which makes little alteration in the sense: and others, instead of "exclude", read "include"; and which is confirmed by the Syriac version, which renders the word "but they would include you"; that is, either they would include, or imprison you under the law, and the bondage of it; or they would monopolize you, and engross all your love to themselves; and which is also the sense of the Arabic version:

that you might affect them; love them, show respect to them, be on their side, follow their directions, imbibe their doctrines, and give up yourselves wholly to their care, and be at their call and command.

Translate, "Am I then become your enemy (an enemy in your eyes) by telling you the truth" (Gal 2:5, Gal 2:14)? He plainly did not incur their enmity at his first visit, and the words here imply that he had since then, and before his now writing, incurred it: so that the occasion of his telling them the unwelcome truth, must have been at his second visit (Act 18:23, see my Introduction). The fool and sinner hate a reprover. The righteous love faithful reproof (Psa 141:5; Pro 9:8).
