But to return to the text. Paul wishes to be humble; he is content that men should take him as they find him, infirmities and all. He has that about him, too, and not unconnected with these high experiences, the very purpose of which is to keep him humble. If the text is correct,[102] he expresses himself with some embarrassment. "And by reason of the exceeding greatness of the revelations--wherefore, that I should not be exalted overmuch, there was given to me a thorn in the flesh, a messenger of Satan to buffet me, that I should not be exalted overmuch." The repetition of the last word shows where the emphasis lies: Paul has a deep and constant sense of the danger of spiritual pride, and he knows that he would fall into it unless a strong counter-pressure were kept up upon him.
I do not feel called on to add another to the numberless disquisitions on Paul's thorn in the flesh. The resources of imagination having been exhausted, people are returning to the obvious. The thorn in the flesh[103] was something painful, which affected the Apostle's body; it was something in its nature purely physical, not a solicitation to any kind of sin, such as sensuality or pride, else he would not have ceased to pray for its removal; it was something terribly humbling, if not humiliating--an affection which might well have excited the contempt and loathing of those who beheld it (Gal. iv. 14, which probably refers to this subject); it had begun after, if not in consequence of, the rapture just described, and stood in a spiritual, if not a physical, relation to it; it was, if not chronic or periodic, at least recurrent; the Apostle knew that it would never leave him. What known malady, incident to human nature, fulfils all these conditions, it is not possible with perfect certainty to say. A considerable mass of competent opinion supports the idea that it must have been liability to epileptic seizures.[104] Such an infirmity Paul might have suffered under in common with men so great as Julius Cæsar and the first Napoleon, as Mahomet, King Alfred, and Peter the Great. But it does not quite satisfy the conditions. Epileptic attacks, if they occur with any frequency at all, invariably cause mental deterioration. Now, Paul distinctly suggests that the thorn was a very steady companion; and as his mind, in spite of it, grew year after year in the apprehension of the Christian revelation, so that his last thoughts are always his largest and best, the epileptic hypothesis has its difficulties like every other. Is it likely that a man who suffered pretty constantly from nervous convulsions of this kind wrote the Second Epistle to the Corinthians after fourteen years of them, or the Epistles to the Romans, Philippians, Colossians, and Ephesians later still? There is, of course, no religious interest in affirming or denying any physical explanation of the matter whatever; but with our present data I do not think a certain explanation is within our reach.
The Apostle himself is not interested in it as a physical affection. He speaks of it because of its spiritual significance, and because of the wonderful spiritual experiences he has had in connexion with it. It was given him, he says: but by whom? When we think of the purpose--to save him from spiritual pride--we instinctively answer, "God." And that, it can hardly be doubted, would have been the Apostle's own answer. Yet he does not hesitate to call it in the same breath a messenger of Satan. The name is dictated by the inborn, ineradicable shrinking of the soul from pain; that agonising, humiliating, annihilating thing, we feel at the bottom of our hearts, is not really of God, even when it does His work. In His perfect world pain shall be no more. It does not need science, but experience, to put these things together, and to understand at once the evil and the good of suffering. Paul, at first, like all men, found the evil overpowering. The pain, the weakness, the degradation of his malady, were intolerable. He could not understand that only a pressure so pitiless and humbling could preserve him from spiritual pride and a spiritual fall. We are all slow to learn anything like this. We think we can take warning, that a word will be enough, that at most the memory of a single pang will suffice to keep us safe. But pains remain with us, and the pressure is continuous and unrelieved, because the need of constraint and of discipline is ceaseless. The crooked branch will not bend in a new curve if it is only tied to it for half an hour. The sinful bias in our natures--to pride, to sensuality, to falsehood, or whatever else---will not be cured by one sharp lesson. The commonest experience in human life is that the man whom sickness and pain have humbled for the moment, the very moment their constraint is lifted, resumes his old habit. He does not think so, but it is really the thorn that has been keeping him right; and when its sharpness is blunted, the edge is taken from his conscience too.
