This very remarkable page in the autobiography of the Apostle shows us that he, too, belonged to the great army of martyrs who, with hearts bleeding and pierced through and through with a dart, yet did their work for God. It is of little consequence what his thorn in the flesh may have been. The original word suggests very much heavier sorrow than the metaphor of 'a thorn' might imply. It really seems to mean not a tiny bit of thorn that might lie half concealed in the finger tip, but one of those hideous stakes on which the cruel punishment of impalement used to be inflicted. And Paul's thought is, not that he has a little, trivial trouble to bear, but that he is, as it were, forced quivering upon that tremendous torture. Unquestionably, what he means is some bodily ailment or other. The hypothesis that the 'thorn in the flesh' was the sting of the animal nature inciting him to evil is altogether untenable, because such a thorn could never have been left when the prayer for its removal was earnestly presented; nor could it ever have been, when left, an occasion for glorifying. Manifestly it was no weakness removable by his own effort, no incapacity for service which in any manner approximated to being a fault, but purely and simply some infliction from God's hand (though likewise capable of being regarded as a 'messenger of Satan') which hindered him in his work, and took down any proud flesh and danger of spiritual exaltation in consequence of the largeness of his religious privileges. Our text sets before us three most instructive windings, as it were, of the stream of thoughts that passed through the Apostle's mind, in reference to this burden that he had to carry, and may afford wholesome contemplation for us to-day. There is, first, the instinctive shrinking which took refuge in prayer. Then there is the insight won by prayer into the sustaining strength for, and the purposes of, the thorn that was not to be plucked out. And then, finally, there is the peace of acquiescence, and a will that accepts--not the inevitable, but the loving. I. First of all we see the instinctive shrinking from that which tortured the flesh, which takes refuge in prayer. There is a wonderful, a beautiful, and, I suppose, an intentional parallel between the prayers of the servant and of the Master. Paul's petitions are the echo of Gethsemane. There, under the quivering olives, in the broken light of the Paschal moon, Jesus 'thrice' prayed that the cup might pass from Him. And here the servant, emboldened and instructed by the example of the Master, 'thrice' reiterates his human and natural desire for the removal of the pain, whatever it was, which seemed to him so to hinder the efficiency and the fulness, as it certainly did the joy, of his service.
