John 13:38

When he had shaken off the dread of being the traitor, and was shown to be one of His own, he afterwards asked boldly himself, while the others held their peace. "What sayest thou, Peter? He said, 'thou canst not,' and thou sayest, 'I can'? Therefore thou shalt know from this temptation that thy love is nothing without the presence of the impulse from above." Whence it is clear that in care for him He allowed even that fall. He desired indeed to teach him even by the first words, but when he continued in his vehemence, He did not indeed throw or force him into the denial, but left him alone, that he might learn his own weakness.

Christ had said that He must be betrayed; Peter replied, "Be it far from Thee, Lord; this shall not happen unto Thee." He was rebuked, but not instructed. On the contrary, when Christ desired to wash his feet, he said, "Thou shall never wash my feet." Again, when he hears, "Thou canst not follow Me now," he saith, "Though all deny Thee, I will not deny Thee." Since then it was likely that he would be lifted up to folly by his practice of contradiction, Jesus next teacheth him not to oppose Him. This too Luke implies, when he telleth us that Christ said, "And I have prayed for thee, that thy faith fail not"; that is, "that thou be not finally lost." In every way teaching him humility, and proving that human nature by itself is nothing.

But, since great love made him apt for contradiction, He now sobereth him, that he might not in after times be subject to this, when he should have received the stewardship of the world, but remembering what he had suffered, might know himself. And look at the violence of his fall; it did not happen to him once or twice, but he was so beside himself, that in a short time thrice did he utter the words of denial, that he might learn that he did not so love as he was loved. And yet, to one who had so fallen He saith again, "Lovest thou Me more than these?" So that the denial was caused not by the cooling of his love, but from his having been stripped of aid from above. He accepteth then Peter's love, but cutteth off the spirit of contradiction engendered by it. "For if thou lovest, thou oughtest to obey Him who is beloved. I said to thee and to those with thee, 'Thou canst not'; why art thou contentious? Knowest thou what a thing it is to contradict God? But since thou wilt not learn in this way that it is impossible that what I say should not come to pass, thou shalt learn it in the denial." And yet this appeared to thee to be much more incredible. For this thou did, not even understand, but of that thou hadst the knowledge in thy heart. Yet still that came to pass which was not even expected.

Wonderful as the zeal of Peter in this matter may be, his promises are beyond his power to fulfil: Christ, however, with the gloom of the threatening tempest in His mind, knowing well how severe will be the temptation and how bitter the persecution, seems as it were to shake His head in sorrow; and then, unfolding to Himself the whole extent of His sufferings, as though it were present to His bodily eyes, beholding the surpassing fury of the Jews in their madness, and seeing clearly all that will come to pass in that hour, He exclaims as though to say: "Dost thou, O Peter, lay down thy life for Me, and sayest thou that thy fear in this matter is as nothing? and supposest thou that thou wilt be strong enough to overcome the trials that will encompass thee?

The Savior, showing him that He alone, and not any man, can promise this with certainty, says: "The rooster will not crow before you deny Me three times," that is, right now; for little time remains. The Lord was saying this late at night, and …

Jesus answered him: Wilt thou lay down thy life for me? Augustine: "Can you go before, you who cannot follow? What do you believe yourself to be? Hear what you are." Verily, verily, I say unto thee, the cock shall not crow till thou hast …

Which sentence may be read in two ways: either as affirming, thou shalt lay down thy life for My sake, but now through fear of the death of the body, thou shalt incur spiritual death: or as mocking; as if He said, Nevertheless, should any one fall, let the example of Peter save him from despair, and teach him that he can without delay obtain pardon from God.

Next, John shows Jesus predicting the denial of Peter. First, Jesus checks Peter's presumption; secondly, he predicts his denial. As to the first we should note that after Christ said you cannot follow me now, Peter was confident of his own strength and said that …

The cock shall not have crowed - That is, cock crowing shall not be over, till thou hast denied me thrice - His three-fold denial was thrice foretold; first, at the time mentioned here; secondly, at that mentioned by St. Luke; lastly, at that recorded by St. Matthew and Mark.

Jesus answered him, If I wash thee not, thou hast no part with me. 9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head. 10 Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.

Jesus answered him, wilt thou lay down thy life for my sake,....

Wilt thou lay down thy life for my sake?--In this repetition of Peter's words there is deep though affectionate irony, and this Peter himself would feel for many a day after his recovery, as he retraced the painful particulars.

Peter said--seeing plainly in these directions how to behave themselves, that He was indeed going from them. Lord, whither goest thou?--having hardly a glimmer of the real truth. Jesus answered, . . . thou canst not follow me now, but thou shalt follow me afterwards--How different from what He said to the Jews: "Whither I go ye cannot come" (Joh 8:21).

Children, I am still with you for a little while. You will look for me, and just as I said to the Jewish authorities, ‘Where I am going you cannot come,’ now I tell you the same. "I give you a new commandment—to love one another. Just as I have loved you, you also are to love one another. Everyone will know by this that you are my disciples—if you have love for one another." Simon Peter said to him, "Lord, where are you going?"

I will lay down my life for you!" Jesus answered, "Will you lay down your life for me? I tell you the solemn truth, the rooster will not crow until you have denied me three times! In this passage we find the Lord Jesus at last alone with His eleven faithful disciples. The traitor, Judas Iscariot, had left the room, and gone out to do his wicked deed of darkness. Freed from his painful company, our Lord opens His heart to His little flock more fully than He had ever done before. Speaking to them for the last time before His passion, He begins a discourse which for touching interest surpasses any portion of Scripture. These verses show us what glory the crucifixion brought both to God the Father and to God the Son. It seems impossible to avoid the conclusion that this was what our Lord had in His mind when He said, "Now is the Son of man glorified, and God is glorified in Him." It is as though He said, "The time of my crucifixion is at hand. My work on earth is finished. An event is about to take place tomorrow, which, however painful to you who love Me, is in reality most glorifying both to Me and My Father." This was a dark and mysterious saying, and we may well believe that the eleven did not understand it. And no wonder!
