The very act of creation – communicating His being to anything outside of Himself – is itself an act of goodness, as well as an act of power…… In the act of giving existence, He is liberal and generous. The being He bestows is a display of His own liberality: He could not confer what He did not have to and what was not deserved unless He was bountiful. The very act of giving being to nothing was an act of choice goodness. God could not create anything without goodness being the chief and necessary motive.
His goodness could not require Him to make the world – His goodness could only move Him to resolve to make a world. He was not bound to erect and fashion it because of His goodness, but He could not frame it without His goodness as the moving cause.
