Christianity demands the crucifixion of the intellect.

Out of love for mankind, and out of despair at my embarrassing situation, seeing that I had accomplished nothing and was unable to make anything easier than it had already been made, and moved by a genuine interest in those who make everything easy, I conceived it as my task to create difficulties everywhere.

How could it occur to anyone to demonstrate that God exists unless one has already allowed Himself to ignore Him? A king's existence is demonstrated by way of subjection and submissiveness. Do you want to try and demonstrate that the king exists? Will you do so by offering a string of proofs, a series of arguments? No. If you are serious, you will demonstrate the king's existence by your submission, by the way you live. And so it is with demonstrating God's existence. It is accomplished not by proofs but by worship. Any other way is but a thinker's pious bungling.

It is so hard to believe because it is so hard to obey.

One should be an enigma not just to others but to oneself too. I study myself. When I'm tired of that I light a cigar to pass the time, and think: God only knows what the good Lord really meant with me, or what He meant to make of me.

Sleeping is the height of genius

Christianity does not oppose debauchery and uncontrollable passions and the like as much as it opposes... flat mediocrity, this nauseating atmosphere, this homey, civil togetherness, where admittedly great crimes, wild excesses, and powerful aberrations cannot easily occur - but where God's unconditional demand has even greater difficulty in accomplishing what it requires: the majestic obedience of submission.
