"God is not only the Father of all good things but he is the mother of all things as well. He is father, for he is the cause of all things and their creator. He is the mother of all things as well, for when creatures have gotten their being from him he still stays with creatures to keep them in being. If God did not remain with creatures after they had started their own life, they would most speedily fall out of being. Falling from God means falling from being into nothingness. It is not so with other causes they can with safety quit the things they cause when these things have gotten being of their own. When the house exists its builder can depart, for it is not the builder alone that makes the house the materials of it he draws from nature. But God provides the creature with the whole of what it is, with form as well as matter, so he is bound to stay with it, or it will promptly drop out of existence."
