What does it mean to say that Jesus is Lord? Is all that we observe in the world today an exemplification of such a reality?
God is above all, and sovereign over all. It's not as if He created the world and it somehow got away from Him. Thus, if Christ is God, then He is truly sovereign over all. The seraphim even now proclaim God's glory permeating all creation (Isaiah 6).
So what's the deal here?
Apparently Christ is sovereign over all, and yet scripture speaks of the gradual submission of all under Him. But how can this be? How do these two statements not contradict?
Well, obviously - God's sovereignty is implicit, but not fully manifested in our experiential reality. We simply do not see or know Him as Lord. We have yet to come to that state of development wherein we know that all things are truly under His Lordship.
This in turn implies that God allows this current state of ignorance, and all that results from it. He is not harried or perplexed or worried about it, but allows it for His own purposes. And why?
We have to run up against, and see, His Lordship for ourselves, in the ordinary gristmill of life and hubbub of the marketplace. For if we do not grow to see it for ourselves, we will not truly ever see it at all.
And here's the added touch that wraps it all up into a nice, neat package: the kind of Lordship that Jesus is gradually acquiring over humanity (through which, in turn, His Lordship over all creation will become manifested!) is one in which He invades humanity from the inside out and asserts sovereignty through us! He becomes a tiny zygote and grows to a babe, through to a child and then up to a fully grown man, up to a heavenly creature having been purged by death into the firstfruits of resurrection life.
Our Lord is the type who asserts sovereignty by coming within, first submitting the heart, then the mind, then the body. All of creation will become submissive from the inside out, and the kind of Lordship He asserts is one of the human being being subsumed into the Godhead and exalted over all... creating a breathlessly awesome new, supernatural community which assists in submitting all creation unto Him (or rather, manifesting His sovereignty), and shames the principalities and the dark powers that be, judging and calling them into submission as well.
What an utterly glorious sovereignty.
