Theodoret of Cyrus: Jesus the Creator and Provider

He adds also something else: carrying all things by the word of his power: he not only made everything but also directs and guides it. He brought out the surpassing degree of his power by saying a word was sufficient for him for the creation and care of everything; he said, remember, "Let there be light, and there was light," and he said, "Let a firmament be made, and so it was made," and he said, "Let a firmament be made, and so it was made," and all the other things in similar fashion.
