to have faith is precisely to lose one's mind so as to win God.

At the bottom of enmity between strangers lies indifference.

...it is presumptuous ridicule of God if someone thinks that only the person who desires great wealth chooses mammon. Alas, the person who insists on having a penny without God, wants to have a penny all for himself. He thereby chooses mammon. A penny is enough, the choice is made, he has chosen mammon; that it is little makes not the slightest difference. The love of God is hatred of the world and love of the world hatred of God.

Faith is holding onto uncertainties with passionate conviction.

Christendom has done away with Christianity without being quite aware of it.

What is a poet? An unhappy man who hides deep anguish in his heart, but whose lips are so formed that when the sigh and cry pass through them, it sounds like lovely music.... And people flock around the poet and say: 'Sing again soon' - that is, 'May new sufferings torment your soul but your lips be fashioned as before, for the cry would only frighten us, but the music, that is blissful.

Life can only be understood backwards; but it must be lived forwards.
