Christ didn't defend himself, yet is the Savior of the World. I can only do what I see my Father does. If this was my Kingdom, my disciples would fight for for me, instead of handing me over to the Jews. There is a way things work and many ways that they don't.
John 5:19
New American Standard Bible 1995
19 Therefore Jesus answered and was saying to them, “Truly, truly, I say to you, the Son can do nothing of Himself, unless it is something He sees the Father doing; for whatever the Father does, these things the Son also does in like manner.
John 18:36
Jesus answered, “My kingdom is not of this world. If My kingdom were of this world, then My servants would be fighting so that I would not be handed over to the Jews; but as it is, My kingdom is not of this realm.”
Luke 8:10
And He said, “To you it has been granted to know the mysteries of the kingdom of God, but to the rest it is in parables, so that seeing they may not see, and hearing they may not understand.
