This announcement was preceded, as I remarked, by that conversation which led to the crystallising of the half-formed convictions of the apostles in a definite creed, 'Thou art the Christ, the Son of the living God.' But that was not all that they needed to know and believe and trust to. That was the first volume of their lesson-book. The second volume was this, that 'Christ must suffer.' And so let us learn the central place which the Cross holds in Christ's teaching. They tell us that the doctrine of Christ as the Sacrifice for the world is not in the Gospels. Where are the eyes that read the Gospels and do not see it? The theory of it is not there; the announcements of it are. And in this latest section of our Lord's ministry, they are fuller and more frequent than in the earlier, for the plain reason which is implied by the preparation through which He passed these disciples, ere He ventured to communicate the mournful and the bewildering fact. There must be, first, the grasp of His Messiahship, and some recognition that He is the Son of God, ere it is possible to go on to speak of the Cross, the full message concerning which could not be spoken until after the Resurrection and the Ascension. But note, you do not understand Christ's Cross unless you bring to it the faith in Christ's Messiahship and the belief in some measure that He is the Son of God. Neither the pathos nor the power of His death is intelligible if it be simply like other deaths--the dying of a man who is born subject to the law of mortality, and who yields to it by natural process. Unless you and I take upon our lips, though with far deeper meaning, the words with which the heathen centurion gazed upon the dying Christ, and say, 'Truly this was the Son of God!' His Cross is common and trivial and insignificant; but if we can thus speak, then it stands before us as the crown of all God's manifestations in the world,' the wisdom of God and the power of God.' And then note, still further, how, without the Cross, these other truths are not the whole gospel. There were disciples then, as there have been disciples since, and as there are to-day, who were willing to accept, 'Thou art the Christ'; and willing in some sense to say 'Thou art the Son of God,' but stumbled when He said, 'The Son of Man must suffer.' Brethren, I venture to urge that the gospel of the Incarnation, precious as it is, is not the whole gospel, and that the full-orbed truth about Jesus Christ is that He is the Christ, and that He died for our sins, and rose again to live for ever, our Priest and King.
