God has a purpose for the universe: that in all things Christ would have the preeminence. This is the Heavenly Bullseye. Since you, dear reader, are part of the universe, you are one of those “all things.” So this purpose includes you.
Actually, this is the same purpose He had in mind for Adam: that Christ would have the preeminence in him. But Adam chose an independent path and failed to give Christ the preeminence. He took the preeminence for himself. Adam missed the mark, which is a life submitted to, and totally dependent upon, God.
