2 Corinthians 12:7-9

He calls it farther the messenger of Satan on this ground, that as all temptations are sent by Satan, so, whenever they assail us, they warn us that Satan is at hand. Hence, at every apprehension of temptation, it becomes us to arouse ourselves, and arm ourselves with promptitude for repelling Satan’s assaults. It was most profitable for Paul to think of this, because this consideration did not allow him to exult like a man that was off his guard. For the man, who is as yet beset with dangers, and dreads the enemy, is not prepared to celebrate a triumph. “The Lord, says he, has provided me with an admirable remedy, against being unduly elated; for, while I am employed in taking care that Satan may not take advantage of me, I am kept back from pride.”

At the same time, God did not cure him by this means exclusively, but also by humbling him. For he adds, to buffet me; by which expression he elegantly expresses this idea. — that he has been brought under control. For to be buffeted is a severe kind of indignity. Accordingly, if any one has had his face made black and blue, he does not, from a feeling of shame, venture to expose himself openly in the view of men. In like manner, whatever be the infirmity under which we labor, let us bear in mind, that we are, as it were, buffeted by the Lord, with the view of making us ashamed, that we may learn humility. Let this be carefully reflected upon by those, especially, who are otherwise distinguished by illustrious virtues, if they have any mixture of defects, if they are persecuted by any with hatred, if they are assailed by any revilings — that these things are not merely rods of the Heavenly Master, but buffetings, to fill them with shame, and beat down all forwardness. Now let all the pious take notice as to this, that they may see how dangerous a thing the “poison of pride” is, as Augustine speaks in his third sermon “On the words of the Apostle,” inasmuch as it “cannot be cured except by poison.” And unquestionably, as it was the cause of man’s ruin, so it is the last vice with which we have to contend, for other vices have a connection with evil deeds, but this is to be dreaded in connection with the best actions; and farther, it naturally clings to us so obstinately, and is so deeply rooted, that it is extremely difficult to extirpate it.

Let us carefully consider, who it is that here speaks — He had overcome so many dangers, tortures, and other evils — had triumphed over all the enemies of Christ — had driven away the fear of death — had, in fine, renounced the world; and yet he had not altogether subdued pride. Nay more, there awaited him a conflict so doubtful, that he could not overcome without being buffeted. Instructed by his example, let us wage war with other vices in such a way, as to lay out our main efforts for the subduing of this one.

But what does this mean — that Satan, who was a

man-slayer from the beginning, (John 8:44,)

was a physician to Paul, and that too, not merely in the cure of the body, but — what is of greater importance — in the cure of the soul? I answer, that Satan, in accordance with his disposition and custom, had nothing else in view than to kill and to destroy, (John 10:10,) and that the goad, that Paul makes mention of, was dipt in deadly poison; but that it was a special kindness from the Lord, to render medicinal what was in its own nature deadly.
