Charles Spurgeon Commentary John 18:35-37

"Pilate answered, Am I a Jew? Thine own nation and the chief priests delivered thee unto me: what hast thou done? Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence. Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end have I been born, and to this end am I come into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice." — John 18:35-37 (ASV)

Thine own nation and the chief priests have delivered thee, unto me: what hast thou done? Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence. Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I unto the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice.

We might have expected that he would have said, "I came into the world that I might be a king." But he explains that, as a Witness to the truth, he was a King.
