The end of the Incarnation is to 'bear witness to the truth.' That witness is the one weapon by which Christ's kingdom is established. That witness is not given by words only, precious as these are, but by deeds which are more than words. These witnessing deeds are not complete till Calvary and the empty grave and Olivet have witnessed at once to the perfect incarnation of divine love, to the perfect Sacrifice for the world's sin, to the Victor over death, and to the opening of heaven to all believers. Jesus is 'the faithful and true Witness,' as John calls Him, not without reminiscences of this passage, just because He is 'the First-begotten of the dead.' As here He told Pilate that He was a 'king,' because a 'witness,' so John, in the passage referred to, bases His being 'Prince of the kings of the earth' on the same fact.
How little Pilate knew that he was standing at the very crisis of his fate! A yielding to the impression that was slightly touching his heart and conscience, and he, too, might have 'heard' Christ's voice. But he was not 'of the truth,' though he might have been if he had willed, and so the words were wind to him, and he brushed aside all the mist, as he thought it, with the light question, which summed up a Roman man of the world's indifference to ideas, and belief in solid facts like legions and swords. 'What is truth?' may be the cry of a seeking soul, or the sneer of a confirmed sceptic, or the shrug of indifference of the 'practical man.'
It was the last in Pilate's case, as is shown by his not waiting for an answer, but ending the conversation with it as a last shot. It meant, too, that he felt quite certain that this man, with his high-strained, unpractical talk about a kingdom resting on such a filmy nothing, was absolutely harmless. Therefore the only just thing for him to have done was to have gone out to the impatient crowd and said so, and flatly refused to do the dirty work of the priests for them, by killing an innocent man. But he was too cowardly for that, and, no doubt, thought that the murder of one poor Jew was a small price to pay for popularity with his troublesome subjects. Still, like all weak men, he was not easy in his conscience, and made a futile attempt to get the right thing done, and yet not to suffer for doing it. The rejection of Barabbas is touched very lightly by John, and must be left unnoticed here. The great contribution to our knowledge which John makes is this private interview between the King who reigns by the truth, and the representative of earthly rule, based on arms and worldly forces.
