Colossians 1:15-20, "
He is the image of the invisible God, the firstborn of all creation, for in him all things in heaven and on earth were created, things visible and invisible, whether thrones or dominions or rulers or powers—
all things have been created through him and for him. He himself is before all things, and
in him all things hold together. He is the head of the body, the church; he is the beginning, the firstborn from the dead, so that he might come to have first place in everything.
For in him all the fullness of God was pleased to dwell, and through him God was pleased to reconcile to himself all things, whether on earth or in heaven, by making peace through the blood of his cross. "
