From Pilgrim at Tinker Creek, Annie Dillard:

“Our life is a faint tracing on the surface of mystery.  The surface of mystery is not smooth, any more than the planet is smooth; not even a single hydrogen atom is smooth, let alone a pine.  Nor does it fit together. . .

“The question from agnosticism is, who turned on the lights?  The question from faith is, whatever for?”
