Just as Jesus left His Throne, with all it's splendor and riches, so He might inherit human souls -  which He values above all else in His vast kingdom; so must we leave our throne that we may inherit what is worth more than all the wealth the world has lusted after throughout history -  HIM.

It may not sound proper, but a king sacrificed himself for me, a pauper.

It may sound strange -  but a king became the servant of all He surveyed.

Rather than demand that his subjects serve him, our king left his throne to serve us.

"Wherefore God also hath highly exalted him, and given him a name which is above every name" because He "made Himself of no reputation,  and took upon Him the form of a servant" "And.....he humbled himself".

So then, real kingdom authority is weilded by those the Father exalts, who he selects to rule in his kingdom. They are not seeking it, they humble themselves by becoming the servant of their subjects- they are not seeking to make a name or reputation for themselves but rather seek to glorify God's name and kingdom.
