12:7 {3} And lest I should be exalted above measure through the abundance of the revelations, there was given to me {f} a thorn in the flesh, the messenger of {g} Satan to buffet me, lest I should be exalted above measure.
(3) An excellent doctrine: why God will have even his best servants to be vexed by Satan, and by every type of temptations: that is, lest they should be too much puffed up, and also that they may be made perfect by being continually exercised in them.
(f) He means sinful lust, that sticks fast in us as it were a thorn, to such a degree that it forced Paul himself who was regenerated to cry out, I do not that good that I would, etc. And he calls it a thorn by a metaphor taken from thorns, or stumps, which are very dangerous and harmful for the feet, if a man walks through woods that are cut down.
(g) Which sets those lusts on fire.
12:7 Lest I should be exalted, etc. This verse shows that 2Co 12:2 refers to himself.
There was given me a thorn in the flesh. Generally supposed to be some painful physical infirmity. See Ga 4:13,14.
The messenger of Satan. All physical evils are due to sin and hence are ascribed to Satan. This thorn was (1) in the flesh; (2) it buffeted or assailed him; (3) it was permitted to prevent undue exaltation, hence must have been humiliating.
12:7 There was given me - By the wise and gracious providence of God. A thorn in the flesh - A visitation more painful than any thorn sticking in the flesh. A messenger or angel of Satan to buffet me - Perhaps both visibly and invisibly; and the word in the original expresses the present, as well as the past, time. All kinds of affliction had befallen the apostle. Yet none of those did he deprecate. But here he speaks of one, as above all the rest, one that macerated him with weakness, and by the pain and ignominy of it prevented his being lifted up mere, or, at least, not less, than the most vehement head ache could have done; which many of the ancients say he laboured under. St. Paul seems to have had a fresh fear of these buffetings every moment, when he so frequently represses himself in his boasting, though it was extorted from him by the utmost necessity.
12:7-10 The apostle gives an account of the method God took to keep him humble, and to prevent his being lifted up above measure, on account of the visions and revelations he had. We are not told what this thorn in the flesh was, whether some great trouble, or some great temptation. But God often brings this good out of evil, that the reproaches of our enemies help to hide pride from us. If God loves us, he will keep us from being exalted above measure; and spiritual burdens are ordered to cure spiritual pride. This thorn in the flesh is said to be a messenger of Satan which he sent for evil; but God designed it, and overruled it for good. Prayer is a salve for every sore, a remedy for every malady; and when we are afflicted with thorns in the flesh, we should give ourselves to prayer. If an answer be not given to the first prayer, nor to the second, we are to continue praying. Troubles are sent to teach us to pray; and are continued, to teach us to continue instant in prayer. Though God accepts the prayer of faith, yet he does not always give what is asked for: as he sometimes grants in wrath, so he sometimes denies in love. When God does not take away our troubles and temptations, yet, if he gives grace enough for us, we have no reason to complain. Grace signifies the good-will of God towards us, and that is enough to enlighten and enliven us, sufficient to strengthen and comfort in all afflictions and distresses. His strength is made perfect in our weakness. Thus his grace is manifested and magnified. When we are weak in ourselves, then we are strong in the grace of our Lord Jesus Christ; when we feel that we are weak in ourselves, then we go to Christ, receive strength from him, and enjoy most the supplies of Divine strength and grace.
