It does not contain more than Nathanael had said at the beginning, but here it is spoken, not as Peter's private belief, but he is the mouthpiece of all. 'Whether it were I or they, so we' believe. This confession summed up the previous development of the disciples, and so marked the end of one stage and the beginning of another. Christ would have them, as it were, take stock of their convictions, as preliminary to opening a new chapter of teaching.
II. That new chapter follows at once. The belief in Him as Messiah is the first story of the building, and the second is next piled on it. The new lesson was a hard one for men whose hopes were coloured by Jewish dreams of a kingdom. They had to see all these vulgar visions melting away, and to face a stern, sad reality. The very fact that He was the Messiah necessarily drew after it the fact of suffering. Whence did the 'must' arise? From the divine purpose, from the necessities of the case, and the aim of His mission. These had shaped prophetic utterances, and hence there was yet another form of the 'must,' namely, the necessity for the Messiah's fulfilling these predictions.
No doubt our Lord led His saddened listeners to many a prophetic saying which current expositions had smoothed over, but which had for many years set before Him His destiny. What a scene that would be--the victim calmly pointing to the tragic words which flashed ominous new meanings to the silent hearers, stricken with awe and grief as the terrible truth entered their minds! What had become of their dreams? Gone, and in their place shame and death. They had fancied a throne; the vision melted into a cross.
We note the minute particularity of Jesus' delineation, and the absolute certainty in His plain declaration of the fact and time of the Resurrection. It is not wonderful that that declaration should have produced little effect. The disciples were too much absorbed and confounded by the dismal thought of His death to have ears for the assurance of His Resurrection. Comfort coming at the end of the announcement of calamities so great finds no entrance into, nor room in, the heart. We all let a black foreground hide from us a brighter distance.
III. The Master's feet mark the disciples' path. If suffering was involved in Messiahship, it is no less involved in discipleship. The cross which is our hope is also our pattern. In a very real sense we have to be partakers of the sufferings of Christ, and no faith in these as substitutionary is vital unless it leads to being conformed to His death. The solemn verses at the close of this lesson draw out the law of Christian self-denial as being inseparable from true discipleship.
Verse 23 lays down the condition of following Jesus as being the daily bearing, by each, of his own cross. Mark that self-denial is not prescribed for its own sake, but simply as the means of 'following.' False asceticism insists on it, as if it were an end; Christ treats it as a means. Mark, too, that it is 'self' which is to be denied--not this or that part of our nature, but the central 'self.' The will is the man, and _it_ is to be brought into captivity to Jesus, so that the true Christian says, 'I live; yet not I, but Christ liveth in me.' That is much deeper, harder, wholesomer teaching than separate austerities or forsakings of this or that.
Verse 24 grounds this great requirement on the broad principle that to make self the main object of life is the sure way to ruin oneself, and that to slay self is the road to true life. Note that it is he who '_would_ save' his life that loses it, because the desire is itself fatal, whether carried out or not; while it is he who _does_ 'lose' his life for Christ that preserves it, because even if the extreme evil has been suffered, the possession of our true lives is not imperilled thereby. No doubt the words refer primarily to literal death, and threaten the cowards who sacrifice their convictions for the sake of keeping a whole skin with the failure of their efforts, while they promise the martyr dying in the arena or at the stake a crown of life. But they go far beyond that. They carry the great truth that to hug self and to make its preservation our first aim is ruinous, and the corresponding one, that to slay self for Christ's sake is to receive a better self. Self-preservation is suicide; self-immolation is not only self-preservation, but self-glorification with glory caught from Jesus. Give yourselves to Him, and He gives you back to yourselves, ennobled and transfigured.
