Pilate refers to Jesusâ€™ own nation and chief priests. Jesus is just like, â€œPilate, this isnâ€™t my nation. These arenâ€™t my priests.â€œ
Not only are His weapons not the weapons of the world, but He doesnâ€™t even gain a kingdom or rule it the way the world does. Jesus just takes all notions of authority and power and flips them on their ear.
â€œSo you are a king?â€ Pilate says this because Jesus just commented about His kingdom. If He has a kingdom, He must be SOME KIND of King?!
But then to Pilate Jesus says: â€œYou say that I am a king. Here is why I came: to bear witness to the truth.â€
If you put that with John 12:27 (for this purpose I came to this hour) then the KEY is that Jesus came to testify to the truth IN LIGHT of the CROSS. Itâ€™s not just that Jesus came to tell us about God, but to show that the truth is so true that He would even stay true and believe to the things He said to death (and beyone). Anybody could spout out wise things about God (though Jesus was wiser than any teacher before Him-John 7:46) but to keep to those teachings and still live them out while going through the crucifixion and beyond is the whole job that was required of Him.
