That Christ is King, has been emphasized in the prophecies of Isaiah.
But, what who or what is against this kingdom of God?
The empire.
Empires vary from kingdoms not only in size, but in nature of leadership.
Here is a basic definition of an empire: an extensive group of states or countries under a single supreme authority, formerly especially an emperor or empress.
The problem is size. And a lack of personal care...and the corruption of power.
Think about this. Who makes up the empire? Who wants tyranny which destroys independence and personal responsibility, freedom of conscience and freedom of religion?
Who wants the empire? Who wants global world government? Think about it. The globalists include UN, Planned Parenthood, Google, Gates, and the "trendies" who do not have a clue what is happening.
