Eyes need light to see. Light bounces off of things, is focused through lenses, and slams into retinas, setting off electrical signals to the brain. Eyes do nothing but receive the light that comes into them.
Eyes add nothing to the light, nor do they produce light.
They are totally passive, utterly given to. Without light, eyes do not work, they are blind, there is no sight. Without Jesus, we are blind. With Jesus, we see, for Jesus is the light of the world. The opposite of seeing is blindness.
