Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.
The completeness of the Godhead. The LORD, God, the Almighty is the all in all. He is the completeness, the allness, He who brought all into being and who directs all things, completely, totally, without beginning, without end.
Remember this the next time you look at a star-filled sky; He is there directing every star. Next time you think of a quark, don't try to look, for sure eyestrain, He is there directing the movement and behavior. HE IS THERE—EVERYWHERE.
