Rulers plan and administrate and govern. They typically do not save. If your house is on fire, it will not be the mayor who shows up to save you from the flames. If America were attacked, the President would serve as the commander in chief of the armed forces. The President would not pick up a weapon, go to the front lines, and fight to save you from the enemy.
 
Jesus is different. He is both infinitely greater than all other rulers, yet also infinitely humbler. He does not consider it beneath his rank as King to risk his life for his subjects. He is willing to fight for us. He is willing to die for us. For King Jesus came into our world for one reason—to save us.
