In light of all Paul has illuminated for us about salvation as a gift of God's free grace and of his choosing his children according to his own will and of our salvation by grace alone, Paul says that God should be glorified.  He is to be glorified in the church as we are filled to the fullness of God and strengthened by his power.  As we live in the manner in which we have been called to live.  These are huge things for us to do, and yet God can do immeasurably more than all we ask or imagine and can even change and transform us to live as his children here on earth.
