John Chrysostom: General Revelation in Creation in Providence

So what was our theme? We studied the question as to how from the beginning God showed providence for our race, and how he gave us useful lessons, without there being any writing or any gift of the Scriptures; and we brought out the fact that he guided us to knowledge of him through discernment of creation.
