John Chrysostom: General Revelation of Sun and Sky

The sky is beautiful, but the reason it was made was for you to adore its maker; the sun is brilliant, but it is for you to worship its creator. If, on the contrary, you are bent on stopping at the wonder of creation, and becoming attached to the beauty of the works, light has become darkness for you -- or, rather, you have turned light into darkness.
