John 13:36-38 - Joseph Benson’s Commentary on the Old and New Testaments

Simon Peter saith, Lord, whither goest thou, &c. The exalted virtue which our Lord had just inculcated, did not make so strong an impression on Peter's mind, as the words which he had before spoken, concerning his going away to a place where his disciples could not come. He therefore replies by thus asking whither he was going. He seems to have supposed that Christ, in consequence of being rejected by the Jews, was about to go to some other part of the earth to erect his throne, where he might reign without disturbance, according to the gross notion which he had of Christ's kingdom. Jesus answered, Whither I go thou canst not follow me now, &c. Thou art too weak at present to follow me in my sufferings: but thou shalt be enabled to do it afterward. From this clause “we gather that the declaration, (John 13:33,) Whither I go ye cannot come, is one of those general propositions whereof there are many in Scripture, which were spoken with a limitation not expressed. Here we are directed to add the limitation, thus, Whither I go ye cannot come NOW. For they were all, equally with Peter, to follow Jesus afterward, by suffering a violent death.” Macknight. Peter said, Lord, why cannot I follow thee now? He was very unwilling to believe that he was so weak as Christ's words intimated he was. He thought he was prepared to do or suffer any thing for his dear Master; adding, I will lay down my life for thy sake As if he had said, Is there any road more terrible than the dark valley of the shadow of death? Yet through these black and gloomy shades I am willing to accompany thee this moment. Jesus answered, Wilt thou lay down thy life, &c. Alas! Peter, thy promises are too large, and uttered with too much confidence to be relied on: thou dost not consider with what reluctance life is parted with, and what a hard task it is to suffer death. Verily, the cock shall not crow, &c. Notwithstanding thy pretended affection and fortitude, a few hours shall not pass till, in great consternation at the danger with which I and my disciples will be threatened, thou shalt basely deny three several times that thou art my disciple. Peter, therefore, had no reason to be elated, though on a former occasion he had confessed Jesus to be the Son of God. And his behaviour, in this instance, affords a very affecting example of human vanity, in the midst of the greatest weakness.
