Verse 25 urges obedience to the precept, by an appeal to reasonable self-regard and common-sense. The abnegation enjoined does not require that we should be indifferent to our own well-being. It is right to consider what will 'profit,' and to act accordingly. The commercial view of life, if rightly taken, with regard to all a man's nature through all the duration of it, will coincide accurately with the most exalted. It 'pays' to follow Christ. Christian morality has not the hypersensitive fear of appealing to self-interest which superfine moralists profess nowadays. And the question in verse 25 admits of only one answer, for what good is the whole world to a dead man? If our accounts are rightly kept, a world gained shows poorly on the one side, against the entry on the other of a soul lost.
Verse 26 tells in what that losing oneself consists, and enforces the original exhortation by the declaration of a future appearance of the Son of man. He of whom Christ is then ashamed loses his own soul. To live without His smile is to die, to be disowned by Him is to be a wreck. To be ashamed of Jesus is equivalent to that base self-preservation which has been denounced as fatal. If a man disavows all connection with Him, He will disavow all connection with the disavower. A man separated from Jesus is dead while he lives, and hereafter will live a living death, and possess neither the world for which he sacrificed his own soul nor the soul for which he sacrificed it.
We cannot but note the authoritative tone of our Lord in these verses. He claims the obedience and discipleship of all men. He demands that all shall yield themselves unreservedly to Him, and that, even if actual surrender of life is involved, it shall be gladly given. He puts our relation to Him as determining our whole present and future. He assumes to be our Judge, whose smile is life, whose averted face darkens the destiny of a man. Whom say ye that He who dared to speak thus conceived Himself to be? Whom say ye that He is?
Verse 27 recalls us from the contemplation of that far-off appearance to something nearer. Remembering the previous announcement of our Lord's sufferings, these words seem intended to cheer the disciples with the hope that the kingdom would still be revealed within the lifetime of some then present. Remembering the immediately preceding words, this saying seems to assure the disciples that the blessed recompense of the life of self-crucifying discipleship is not to be postponed to that future, but may be enjoyed on earth. Remembering Christ's word, 'Except a man be born again, he cannot see the kingdom of God,' we doubt whether there is any reference here to the destruction of Jerusalem, as is commonly understood. Are not the words rather a declaration that they who are Christ's true disciples shall even here enter into the possession of their true selves, and find the Messianic hopes more than fulfilled? The future indicated will then be no more remote than the completion of His work by His death and Resurrection, or, at the farthest, the descent of the Holy Spirit at Pentecost, by which the fuller life of renewed natures was bestowed on those who were following Jesus in daily self-surrender.
