It is all very illogical, of course, and very absurd. If we can accept the _four_ words, why not accept all _six_? If we credit the head of the text, why cavil at the tail? Sometimes the absurdity of such irrational behavior will break upon a man and set him laughing at his own stupidity. Mr. Spurgeon had some such experience. 'Gentlemen,' he said, one Friday afternoon, in an address to his students, 'Gentlemen, there are many passages of Scripture which you will never understand until some trying or singular experience shall interpret them to you. The other evening I was riding home after a heavy day's work; I was very wearied and sore depressed; and, swiftly and suddenly as a lightning flash, that text laid hold on me: _My grace is sufficient for thee!_ On reaching home, I looked it up in the original, and at last it came to me in this way. _MY grace is sufficient for THEE_! "Why," I said to myself, "I should think it is!" and I burst out laughing. I never fully understood what the holy laughter of Abraham was like until then. It seemed to make unbelief so absurd. It was as though some little fish, being very thirsty, was troubled about drinking the river dry; and Father Thames said: "Drink away, little fish, my stream is sufficient for thee!" Or as if a little mouse in the granaries of Egypt, after seven years of plenty, feared lest it should die of famine, and Joseph said: "Cheer up, little mouse, my granaries are sufficient for thee!" Again I imagined a man away up yonder on the mountain saying to himself: "I fear I shall exhaust all the oxygen in the atmosphere." But the earth cries: "Breathe away, O man, and fill thy lungs; my atmosphere is sufficient for thee!"' John Bunyan enjoyed a moment's merriment of the same kind when he threw the last two words into the scale and saw his despair dwindle into insignificance on the instant. III Some such thought shines through the passage in which Paul tells us how the great words came to him. He was irritated by his thorn; he prayed repeatedly for its removal; but the only answer that he received was this: _My grace is sufficient for thee!_ Grace sufficient for a thorn! It is an almost ludicrous association of ideas! It is so easy for Bunyan to believe that the divine grace is sufficient for the wide, wide world; it is so difficult to realize that it is sufficient for him! It is so easy for Wesley to believe in the forgiveness of sins: it is so difficult for him to believe in the forgiveness of his own! It is so easy for Paul to believe in the grace that is sufficient to redeem a fallen race: it is so difficult for him to believe in the grace that can fortify him to endure his thorn!
