Here is an extended quote from Pascal (from Penguin Classics' Pensees, #919), from a section called "The Mystery of Jesus." I think that it has an Advent message for us, even though it is about Christ's agony:
Jesus suffers in his passion the torments inflicted upon him by men, but in his agony he suffers the torments which he inflicts on himself. He was troubled [John 11:33. Reflexive verb in the Latin Vulgate]. The punishment is inflicted by no human, but by an almighty hand, and only he that is almighty can bear it.
Jesus seeks some comfort at least from his three dearest friends, and they sleep: he asks them to bear with him a while, and they abandon him with complete indifference, and with so little pity that it did not keep them awake even for a single moment. And so Jesus was abandoned to face the wrath of God alone.
Jesus is alone on earth, not merely with no one to fear and share his agony, but with no one even to know of it. Heaven and he are the only ones to know.
Jesus is in a garden, not of delight, like the first Adam, who there fell and took with him the rest of mankind, but of agony, where he was saved himself and all mankind.
He suffers this anguish and abandonment in the horror of the night.
I believe that this is the only occasion on which Jesus ever complained. But then he complained as though he could no longer contain his overflowing grief: 'My soul is exceeding sorrowful, even unto death' [Matt. 26:38].
Jesus seeks companionship and solace from men.
It seems to me that this is unique in his whole life, but he finds none, for his disciples are asleep.
Jesus will be in agony until the end of the world. There must be no sleeping during that time.
Jesus, totally abandoned, even by the friends he had chosen to watch with him, is vexed when he finds them asleep because of the dangers to which they are exposing not him but themselves, and he warns them for their own safety and their own good, with warm affection in the face of their ingratitude. And warns them: 'The spirit is willing but the flesh is weak' [Matt. 26:41].
Jesus finding them asleep again, undeterred by consideration either for him or for themselves, is kind enough not to wake them up and lets them take their rest.
Jesus prays, uncertain of the will of the Father, and is afraid of death. But once he knows what it is, he goes to meet it and offer himself up. Let us be going [Matt. 26:46]. He went forth [Jn. 18:4].
Jesus asked of men and he was not heard.
Jesus brought about the salvation of his disciples while they slept. He has done this for each of the righteous while they slept, in nothingness before their birth and in their sins after their birth.
He prays only once that the cup might pass from him, even then submitting himself to God's will, and twice that it should come if it must be so.
Jesus weary at heart.
Jesus, seeing all his friends asleep and all his enemies watchful, commends himself utterly to his Father.
Jesus disregards the emnity of Judas, and sees only in him God's will, which he loves; so much so that he calls him friend.
Jesus tears himself away from his disciples to enter upon his agony: we must tear ourselves away from those who are nearest and dearest to us in order to imitate him. While Jesus remains in agony and cruellest distress, let us pray longer.
We implore God's mercy, not so that he shall leave us in peace with our vices, but so that he may deliver us from them.
"Jesus will be in agony until the end of the world. There must be no sleeping during that time."
