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.

God is present in the moment of choice, not in order to watch but in order to be chosen. Therefore, each person must choose. Terrible is the battle, in a person's innermost being, between God and the world. The crowning risk involved lies in the possession of choice.

Sin is in itself separation from the good, but despair over sin is separation a second time.

Philosophy is life's dry-nurse, who can take care of us - but not suckle us.

It is human self-renunciation when a man denies himself and the world opens up to him. But it is Christian self-renunciation when he denies himself and, because the world precisely for this shuts itself up to him, he must as one thrust out by the world seek God's confidence. The double-danger lies precisely in meeting opposition there where he had expected to find support, and he has to turn about twice; whereas the merely human self-resignation turns once.

It is perfectly true, as philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.
