Big, absolutely gigantic, and let me say again BIG!
The Son is the image of the invisible God, the firstborn over all creation. For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
Not only is that stunning and beautiful, but it is loaded with a mystery we can experience but not pin down. Lets listen to those expansive words again, "all creation, all things, visible and invisible, all things, all things, all things, the beginning and the firstborn, in everything, all fullness, all things."
And the church is the body of that? Seems like it should be a big church with a big heart.
