Advent and Christmas liturgies and customs are replete with royal imagery. "Let him enter, the King of Glory." The one who is coming is the "King of Kings" whose reign will last forever. The gifts of the Magi are the homage proper to a king.
Not only is there something human about the longing for a just Ruler, but personhood, as such, indicates royalty. We are "a chosen race, a royal priesthood". This is a claim not just about the Jews, but about every person, created in the Image and Likeness of God.
We are made to have dominion.
"Human beings were not created for slavery, but to be the lords of creation."
