It is a profound political reality that Christ now occupies the supreme seat of cosmic authority. The kings of this world and all secular governments may ignore this reality, but they cannot undo it. The universe is no democracy. It is a monarchy. God himself has appointed his beloved Son as the preeminent King. Jesus does not rule by referendum, but by divine right. In the future every knee will bow before him, either willingly or unwillingly. Those who refuse to do so will have their knees broken with a rod of iron.
