What is truth? - This question was probably asked in contempt, and hence Jesus did not answer it. Had the question been sincere, and had Pilate really sought it as Nicodemus had done John 3, Jesus would not have hesitated to explain to him the nature of his kingdom. They were now alone in the judgment-hall John 18:33, and as soon as Pilate had asked the question, without waiting for an answer, he went out. It is evident that he was satisfied, from the answer of Jesus John 18:36-37, that he was not a king in the sense in which the Jews accused him; that he would not endanger the Roman government, and consequently that he was innocent of the charge alleged against him. He regarded him, clearly, as a fanatic poor, ignorant, and deluded, but innocent and not dangerous. Hence, he sought to release him; and, hence, in contempt, he asked him this question, and immediately went out, not expecting an answer.
This question had long agitated the world. It was the great subject of inquiry in all the schools of the Greeks. Different sects of philosophers had held different opinions, and Pilate now, in derision, asked him, whom he esteemed an ignorant fanatic, whether he could solve this long-agitated question. He might have had an answer. If he had patiently waited in sincerity, Jesus would have told him what it was. Thousands ask the question in the same way. They have a fixed contempt for the Bible; they deride the instructions of religion; they are unwilling to investigate and to wait at the gates of wisdom; and hence, like Pilate, they remain ignorant of the great Source of truth, and die in darkness and in error. All might find truth if they would seek it; none ever will find it if they do not apply for it to the great source of light the God of truth, and seek it patiently in the way in which he has chosen to communicate it to mankind. How highly should we prize the Bible! And how patiently and prayerfully should we search the Scriptures, that we may not err and die forever! See the notes at John 14:6.
I find in him no fault - See Luke 23:4.
