This the cry of youth - ardent, impulsive, self-confident. It does not wait to calculate the ridges and hummocks that lie between it and its goal, but supposes that it will be able to skate the entire distance over the glistening azure blue ice. Without hesitation it counts on being able to brave all difficulty, surmount all hardship, drink the cup, and be baptized with the baptism.
But these men slept in Gethsemane, forsook the Master when He was arrested, and one of them at least failed Him at the cross. Creature-might cannot carry us in the hour of our greatest peril. We can vaunt ourselves as we may; but we have to learn that we can only follow Christ in His cup and baptism, after we have been endued with the Spirit of Pentecost. I once knew two who said these words to God, when He presented them with the cup of suffering and death. They did not know all it involved; and they confessed afterward that they could never have stood to their choice, had they not been graciously and repeatedly enabled. But at the end they could not wish it to have been otherwise.
How different were the experiences of these two men! To one the cup and baptism came swiftly, when he fell beneath the beheading axe of Herod (Act 12:2); to the other they came in long, long years of sharing in the patience of Jesus Christ. These are different aspects of the same fellowship of suffering - swift death, or long waiting; but in both nearness to Jesus. We have no right to cherish the assurance of sitting right and left of the throne, if that only means our own power, authority, glory. But if it means nearness to Jesus, we may count on it with the utmost assurance.
