God is light and in him there is no darkness. He is the light of the sun and the power thereof by which it was made; he is also the light of the moon and the power by which it was made; he is the light of the stars and the power by which it was made. He [God] says it is the same light that enlightens the understanding of men. What, have we a mental light and a visual light, all proceeding from the same source? Yes, so says the scripture, and so says science when rightly comprehended.
