Who is the image of the invisible God, the first born of every creature; for by him were all things created… and he is before all things,… and he is the head of the body,… for it pleased the Father that in him should all fullness dwell; and having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven. Colossians 1:15-20.
