God creates, not that there may be witnesses to render Him His due glory, but beings who shall rejoice in it as He rejoices in it Himself and who, participating in His being, participate at the same time in His beatitude. It is not therefore for Himself, but for us, that God seeks His glory; it is not to gain it, for He posses it already, nor to increase it, for already it is perfect, but to communicate it to us.
~ Étienne Gilson
