John 18:36-37

Jesus replied, “My kingdom is not of this world [nor does it have its origin in this world]. If My kingdom were of this world, My servants would be fighting [hard] to keep Me from being handed over to the Jews; but as it is, My kingdom is not of this world.” So Pilate said to Him, “Then You are a King?” Jesus answered, “You say [correctly] that I am a King. This is why I was born, and for this I have come into the world, to testify to the truth. Everyone who is of the truth [who is a friend of the truth and belongs to the truth] hears and listens carefully to My voice.”
