So He could rejoin the three, in whose sympathy and watchfulness He had trusted--and they all were asleep! Surely that was one ingredient of bitterness in His cup. We wonder at their insensibility; and how they must have wondered at it too, when after years taught them what they had lost, and how faithless they had been! Think of men who could have seen and heard that scene, which has drawn the worshipping regard of the world ever since, missing it all because they fell asleep! They had kept awake long enough to see Him fall on the ground and to hear His prayer, but, worn out by a long day of emotion and sorrow, they slept.
Jesus was probably rapt in prayer for a considerable time, perhaps for a literal 'hour.' He was specially touched by Peter's failure, so sadly contrasted with his confident professions in the upper room; but no word of blame escaped Him. Rather He warned them of swift-coming temptation, which they could only overcome by watchfulness and prayer. It was indeed near, for the soldiers would burst in, before many minutes had passed, polluting the moonlight with their torches and disturbing the quiet night with their shouts. What gracious allowance for their weakness and loving recognition of the disciples' imperfect good lie in His words, which are at once an excuse for their fault and an enforcement of His command to watch and pray! 'The flesh is weak,' and hinders the willing spirit from doing what it wills. It was an apology for the slumber of the three; it is a merciful statement of the condition under which all discipleship has to be carried on. 'He knoweth our frame.' Therefore we all need to watch and pray, since only by such means can weak flesh be strengthened and strong flesh weakened, or the spirit preserved in willingness.
The words were not spoken in reference to Himself, but in a measure were true of Him. His second withdrawal for prayer seems to witness that the victory won by the first supplication was not permanent. Again the anguish swept over His spirit in another foaming breaker, and again He sought solitude, and again He found tranquillity--and again returned to find the disciples asleep. 'They knew not what to answer Him' in extenuation of their renewed dereliction.
Yet a third time the struggle was renewed. And after that, He had no need to return to the seclusion, where He had fought, and now had conclusively conquered by prayer and submission. We too may, by the same means, win partial victories over self, which may be interrupted by uprisings of flesh; but let us persevere. Twice Jesus' calm was broken by recrudescence of horror and shrinking; the third time it came back, to abide through all the trying scenes of the passion, but for that one cry on the Cross, 'Why hast Thou forsaken Me?' So it may be with us.
The last words to the three have given commentators much trouble. 'Sleep on now, and take your rest,' is not so much irony as 'spoken with a kind of permissive force, and in tones in which merciful reproach was blended with calm resignation.' So far as He was concerned, there was no reason for their waking. But they had lost an opportunity, never to return, of helping Him in His hour of deepest agony. He needed them no more. And do not we in like manner often lose the brightest opportunities of service by untimely slumber of soul, and is not 'the irrevocable past' saying to many of us, 'Sleep on now since you can no more do what you have let slip from your drowsy hands'?
'It is enough' is obscure, but probably refers to the disciples' sleep, and prepares for the transition to the next words, which summon them to arise, not to help Him by watching, but to meet the traitor. They had slept long enough, He sadly says. That which will effectually end their sleepiness is at hand. How completely our Lord had regained His calm superiority to the horror which had shaken Him is witnessed by that majestic 'Let us be going.' He will go out to meet the traitor, and, after one flash of power, which smote the soldiers to the ground, will yield Himself to the hands of sinners.
