But making Jesus my King removes me from the human power struggle.  Men of power fear this more than anything.  Authoritarian leaders know their power will erode if people no longer grasp for it.  The Kingdom of God is the greatest fear of the kings of men.  

Further, if I am obedient to Jesus as King, I will obey human rulers only to the extend that doing so will not compromise obedience to Jesus.  No tyrant likes a citizen who is allegiant to the True King.
