Matthew 26:40

Or the sleep which He would have them forego is not bodily rest, for which at this critical time there was no room, but mental torpor, the sleep of unbelief.

Not without reason doth He inveigh against Peter most, although the others also had slept; but to make him feel by this also, for the cause which I mentioned before. Then because the others also said the same thing (for when Peter had said (these are the words), "Though I must die with Thee, I will not deny Thee; likewise also," it is added, "said all the disciples"); He addresses Himself to all, convicting their weakness. For they who are desiring to die with Him, were not then able so much as to sorrow with Him wakefully, but sleep overcame them.

However, even these He dismisses: "And He went on a little farther, and prayeth, saying, Father, if it be possible, let this cup pass from me; nevertheless not as I will, but as Thou wilt. And He cometh unto them, and findeth them sleeping, and saith unto Peter, What, could ye not watch with me one hour? Watch and pray, that ye enter not into temptation; the spirit indeed is willing, but the flesh is weak." And He prays with earnestness, in order that the thing might not seem to be acting. And sweats flow over him for the same cause again, even that the heretics might not say this, that He acts the agony. Therefore there is a sweat like drops of blood, and an angel appeared strengthening Him, and a thousand sure signs of fear, lest any one should affirm the words to be feigned. For this cause also was this prayer. By saying then, "If it be possible, let it pass from me," He showed His humanity; but by saying, "Nevertheless not as I will, but as Thou wilt," He showed His virtue and self-command, teaching us even when nature pulls us back, to follow God. For since it was not enough for the foolish to show His face only, He uses words also. Again, words sufficed not alone, but deeds likewise were needed; these also He joins with the words, that even they who are in a high degree contentious may believe, that He both became man and died. For if, even when these things are so, this be still disbelieved by some, much more, if these had not been. See by how many things He shows the reality of the incarnation: by what He speaks, by what He suffers. After that He cometh and saith to Peter, as it is said, "What, couldest thou not watch one hour with me?" All were sleeping, and He rebukes Peter, hinting at him, in what He spake. […]

Or, The Lord prayed thrice, to teach us to pray for pardon of sins past, defence against present evil, and provision against future perils, and that we should address every prayer to Father, Son, and Holy Spirit, and that our spirit, soul, and body should be kept in safety.

And he cometh to his disciples. Here he rebukes the failing of the disciples. And first, the failing is set forth; second, the rebuke; third, the admonition; fourth, the reason for the admonition. When he had prayed, he cometh to his disciples and findeth them …

And He cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with Me one hour? Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak. Because Peter and …

And he cometh unto the disciples,....

He - saith unto Peter - He addressed himself more particularly to this apostle, because of the profession he had made, Mat 26:33; as if he had said: “Is this the way you testify your affectionate attachment to me? Ye all said you were ready to die with me; what, then, cannot you watch One hour?” Instead of ουκ ισχυσατε, could Ye not, the Codex Alexandrinus, the later Syriac in the margin, three of the Itala, and Juvencus, read ουκ ισχυσας, couldst Thou not - referring the reproach immediately to Peter, who had made the promises mentioned before.

The verses we have now read describe what is commonly called Christ’s agony at Gethsemane. It is a passage which undoubtedly contains deep and mysterious things. We ought to read it with reverence and wonder, for there is much in it which we cannot fully comprehend. Why do we find our Lord so “sorrowful and very heavy,” as he is here described? What are we to make of his words, “My soul is exceeding sorrowful even unto death.”

The verses we have now read describe what is commonly called Christ’s agony at Gethsemane. It is a passage which undoubtedly contains deep and mysterious things. We ought to read it with reverence and wonder, for there is much in it which we cannot fully comprehend. Why do we find our Lord so “sorrowful and very heavy,” as he is here described? What are we to make of his words, “My soul is exceeding sorrowful even unto death.” Why do we see him going apart from his disciples, and falling on his face, and crying to his Father with strong cries, and thrice repeated prayer? Why is the almighty Son of God, who had worked so many miracles, so heavy and disquieted? Why is Jesus, who came into the world to die, so like one ready to faint at the approach of death? Why is all this? There is but one reasonable answer to these questions: the weight that pressed down our Lord’s soul was not the fear of death and its pains. Thousands have endured the most agonizing sufferings of body, and died without a groan, and so, no doubt, might our Lord. But the real weight that bowed down the heart of Jesus was the weight of the sin of the world, which seems to have now pressed down upon him with peculiar force: it was the burden of our guilt imputed to him, which was now laid on him, as on the head of the scapegoat. How great that burden must have been no human heart can conceive! It is known only to God. Well may the Greek Litany speak of the “unknown sufferings of Christ.” The words of Scott on this subject are probably correct: “Christ at this time endured as much misery of the same kind with that of condemned spirits, as could possibly consist with a pure conscience, perfect love of God and man, and an assured confidence of a glorious event.”
