"There are?"
Well, one thing we know as Christians, Heaven is surely a monarchy.
Though I'm not pretending to know the mind of God,, it does follow that if Jesus Christ was King of the Jews, King of Kings, and King of Heaven and Earth, and He made man in His own image and likeness, it wouldn't really be surprising if He intended earthly nations to be monarchies ruled over by beneficent Kings. Just a thought.
And you support that notion? That we should have a king?
