It is interesting to remember that it was after this night spent in prayer that He delivered the remarkable discourse recorded in the sixth chapter of St. John, in which He speaks so plainly about giving His flesh for the life of the world. It is evident, then, that, if any question had arisen in His mind as to the path of duty, when He was suddenly confronted with the enthusiastic desire of the multitudes to crown Him at once, it was speedily set at rest: He now plainly saw that it was not the will of His Father in heaven that He should take advantage of any such stirring of worldly desire, that He must give no encouragement to any, except those who were hungering and thirsting after righteousness, to range themselves upon His side. Hence, no doubt, the sifting nature of the discourse He delivered the following day. He is eager to gather the multitudes to Himself; but He cannot allow them to come under any false assumption;--He must have spiritually-minded disciples, or none at all: accordingly He makes His discourse so strongly spiritual, directs their attention so far away from earthly issues to the issues of eternity ("I will raise him up at the last day" is the promise He gives over and over again, whereas they wanted to be raised up then and there to high places in the world), that not only did the multitude lose all their enthusiasm, but "from that time many of His disciples went back, and walked no more with Him," while even the Twelve themselves were shaken in their allegiance, as seems evident from the sorrowful question with which He turned to them: "Will ye also go away?" We may reverently suppose, then, that our Lord was occupied, during the early part of the night, with thoughts like these--in preparation, as it were, for the faithful words He will speak and the sad duty He will discharge on the morrow. Meantime a storm has arisen on the lake--one of those sudden and often terrible squalls to which inland waters everywhere are subject, but which are greatly aggravated here by the contrast between the tropical climate of the lake, 620 feet below the level of the Mediterranean, and the cool air on the heights which surround it. The storm becomes fiercer as the night advances. The Saviour has been much absorbed, but He cannot fail to notice how angry the lake is becoming, and to what peril His loved disciples are exposed. As the Passover was nigh, the moon would be nearly full, and there would be frequent opportunities, between the passing of the clouds, to watch the little boat. As long as there seems any prospect of their weathering the storm by their own exertions He leaves them to themselves; but when it appears that they are making no progress, though it is evident that they are "toiling in rowing," He sets out at once to their relief.
