How deeply affecting is all this! Only think of a saint of God, and an apostle of Christ, cursing and swearing that he did not know his Lord! Does the reader feel disposed to question the fact that Peter was, spite of all this, a genuine saint of God? Some do question it, but their questioning is a gross mistake. They find it hard to conceive such a thing as a true child of God falling so terribly. It is because they have not yet thoroughly learnt what flesh is. Peter was as really a saint of God in the palace of the high priest as he was on the mount of transfiguration. But he had to learn himself, and that, too, by as humiliating and painful a process as any soul could well be called to pass through. Doubtless, if any one had told Peter, a few days before, that he would ere long curse and swear that he did not know his Lord, he would have shrunk with horror from the thought. He might have said, like one of old, "Is thy servant a dog that he should do this thing?" Yet so it was. We know not what we may do until we are in the circumstances. The great thing for us all is to walk humbly with our God day by day, deeply sensible of our own utter weakness, and clinging to Him who is able to keep us from falling. We are safe only in the shelter of His presence. Left to ourselves, we are capable of anything, as our apostle found to his deep sorrow.
But the Lord was watching over His poor erring servant. He never lost sight of him for a single moment, He had His eye upon the whole process. The devil would have smashed the vessel in hopeless fragments if he could. But he could not. He was but an instrument in the divine hand to do a work for Peter which Peter had failed to do for himself. "Simon, Simon, behold Satan hath desired to have you, that he may sift you as wheat; but I have prayed for thee, that thy faith fail not; and when thou art converted (or restored), strengthen thy brethren."
Here we are permitted to see the root of the matter. Peter needed to be sifted, and Satan was employed to do the work--just as in the case of Job, and the man in 1 Cor. v. It seems very wonderful, very mysterious, very solemn, that Satan should be so used. Yet so it is. God uses him "for the destruction of the flesh." He cannot touch the spirit. That is eternally safe. But it is terrible work to get into Satan's sieve. Peter found it so, and so did Job, and so did that erring Corinthian.
But oh, the _grace_ of those words! "I have prayed for thee"--not that he might not fall, but, having fallen, that his faith might not fail, his confidence might not give way. Nothing can surpass the grace that shines out here. The blessed One knew all that was to happen--the shameful denial--the cursing and swearing; and yet, "I have prayed for thee that thy faith fail not"--that thy confidence in the eternal stability of my grace may not give way.
Perfectly marvelous! And then, the _power_ of that look! "The Lord turned, and looked upon Peter." It was this that broke Peter's heart, and drew forth a flood of bitter, penitential tears.
