The Notebooks of Malte Laurids Brigge

Is it possible that there are people who say "God" and suppose they mean something shared by all? — Only consider two schoolboys: one of them buys a knife, and the other buys an identical one on the same day. And a week later, they show each other the two knives, and they turn out to be only remotely similar, so differently have they been shaped by different hands. ... Is it possible to believe we could have a god without making use of him?

A thought struck me abruptly: My God, you do exist, then. There are proofs of Your existence. I had forgotten them all, and never demanded any either, for what an overwhelming obligation would come with this certainty. And yet that is what is now being shown to me.
