I don't believe for a minute that the proof of God's existence is achieved. My faith prohibits me from believing that the proof of God's existence can ever be adduced. My God is not an object for verification, He is a subject for love. My faith is not knowledge, it is acceptance. It is a matter not of calculation but of trust.

We have no time to waste on insignificant books, hollow books, books that are there to please...We want books that cost their authors a great deal, books where you can feel the years of work, the backache, the writer's block, the author's panic at the thought that he might be lost: his discouragement, his courage, his anguish, his stubbornness, the risk of failure that he has taken.

We want books that are written for those of us who doubt everything, who cry over the least little thing, who are startled by the slightest noise.
