“A man's physical hunger does not prove that man will get any bread; he may die of starvation on a raft in the Atlantic. But surely a man's hunger does prove that he comes of a race which repairs its body by eating and inhabits a world where eatable substances exist. In the same way, though I do not believe (I wish I did) that my desire for Paradise proves that I shall enjoy it, I think it a pretty good indication that such a thing exists and that some men will.”

“Faith belongs to the human spirit. Faith is faith. Humanity is divided by religion, religion is the divider of humanity. If every human could be removed of their blindfolds and see that faith is in itself faith and that this is something which belongs to each and every human being, then at that time the dividers of religion will suddenly mean nothing and we will all see that we are united by faith in and of itself. There is only one faith and it is called faith. And no man needs to prove to another man that what he believes in exists, because even if it does not exist, his faith is his belief that it is there, that something is there, and that in itself is faith. So I do not need to prove to any man that what I believe in exists or not, there is no such contest between man, my faith breathes in the body of my belief; the fact that I believe is the breath of my faith.”

“My most recent faith struggle is not one of intellect. I don’t really do that anymore. Sooner or later you just figure out there are some guys who don’t believe in God and they can prove He doesn't exist, and there are some other guys who do believe in God and they can prove He does exist, and the argument stopped being about God a long time ago and now it’s about who is smarter, and honestly I don’t care.”

“I believe this is so and I'm prepared to vouch for it, because it seems to me that the meaning of man's life consists in proving to himself every minute that he's a man and not a piano key. And man will keep proving it and paying for it with his own skin; he will turn into a troglodyte if need be. And, since this is so, I cannot help rejoicing that things are still the way they are and that, for the time being, nobody knows worth a damn what determines our desires.”

“The love between writer and a reader is never celebrated. It can never be proved to exist. But he was the man I loved most. He was the reader for whom I wrote.That’s what my writing was. Messages in bottles.”

“The Christian says, 'Creatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water. Men feel sexual desire: well, there is such a thing as sex. If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world. If none of my earthly pleasures satisfy it, that does not prove that the universe is a fraud. Probably earthly pleasures were never meant to satisfy it, but only to arouse it, to suggest the real thing. If that is so, I must take care, on the one hand, never to despise, or to be unthankful for, these earthly blessings, and on the other, never to mistake them for the something else of which they are only a kind of copy, or echo, or mirage. I must keep alive in myself the desire for my true country, which I shall not find till after death; I must never let it get snowed under or turned aside; I must make it the main object of life to press on to that country and to help others to do the same.”
