How did the Cross glorify Christ? In two ways. It was the revelation of His heart; it was the throne of His sovereign power.
It was the revelation of His heart. All his life long He had been trying to tell the world how much He loved it. His love had been, as it were, filtered by drops through His words, through His deeds, through His whole demeanour and bearing; but in His death it comes in a flood, and pours itself upon the world. All His life long he had been revealing His heart, through the narrow rifts of His deeds, like some slender lancet windows; but in His death all the barriers are thrown down, and the brightness blazes out upon men. All through His life He had been trying to communicate His love to the world, and the fragrance came from the box of ointment exceeding precious, but when the box was broken the house was filled with the odour.
For Him to be known was to be glorified. So pure and perfect was He, that revelation of His character and glorification of Himself were one and the same thing. Because His Cross reveals to the world for all time, and for eternity, too, a love which shrinks from no sacrifice, a love which is capable of the most entire abandonment, a love which is diffused over the whole surface of humanity and through all the ages, a love which comes laden with the richest and the highest gifts, even the turning of selfish and sinful hearts into its own pure and perfect likeness, therefore does He say, in contemplation of that Cross which was to reveal Him for what He was to the world, and to bring His love to every one of us, 'Now is the Son of Man glorified.'
We can fancy a mother, for instance, in the anticipation of shame, and ignominy, and suffering, and sorrow, and death which she encounters for the sake of some prodigal child, forgetting all the ignominy, and the shame, and the suffering, and the sorrow, and the death, because all these are absorbed in the one thought: 'If I bear them, my poor, wandering, rebellious child will know at last how much I loved him.' So Christ yearns to impart the knowledge of Himself to us, because by that knowledge we may be won to His love and service; and hence when He looks forward to the agony, and contumely, and sorrow of the close, every other thought is swallowed up in this one: 'They will be the means by which the whole world will find out how deep my heart of love to it was.' Therefore does He triumph and say, 'Now is the Son of Man glorified.'
Still further, He regards His Cross as the means of His glorifying, because it is His throne of saving power. The paradoxical words of our text rest upon His profound conviction that in His death He was about to put forth a mightier and diviner power than ever He had manifested in His life. They are the same in effect and in tone as the great words: 'I, if I be lifted up, will draw all men unto Me.' Now I want you to ask yourselves one question: In what sense is Christ's Cross Christ's glorifying, unless His Cross bears an altogether different relation to His life from what the death of a great teacher or benefactor ordinarily bears to his? It is impossible that Christ could have spoken such words as these of my text if He had simply thought of His death as a Plato or a John Howard might have thought of his, as being the close of his activity for the welfare of his fellows. Unless Christ's death has in it some substantive value, unless it is something more than the mere termination of His work for the world, I see not how the words before us can be interpreted. If His death is His glorifying, it must be because in that death something is done which was not completed by the life, however fair; by the words, however wise and tender; by the works of power, however restorative and healing. Here is something more than these present. What more? This more, that His Cross is the 'propitiation for the sins of the whole world.' He is glorified therein, not as a Socrates might be glorified by his calm and noble death; not because nothing in His life became Him better than the leaving of it; not because the page that tells the story of His passion is turned to by us as the tenderest and most sacred in the world's records; but because in that death He wrestled with and overcame our foes, and because, like the Jewish hero of old, dying, He pulled down the house which our tyrants had built, and overwhelmed them in its ruins. 'Now is the Son of Man glorified.'
