Sin is: before God, or with the conception of God, in despair not to will to be oneself, or in despair to will to be oneself. Thus sin is intensified weakness or intensified defiance: sin is the intensification of despair. The emphasis is on before God, or with a conception of God; it is the conception of God that makes sin dialectically, ethically, and religiously what lawyers call 'aggravated' despair.

There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.

I am convinced that God is love, this thought has for me a primitive lyrical validity. When it is present to me, I am unspeakably blissful, when it is absent, I long for it more vehemently than does the lover for his object.

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.

Language has time as its element; all other media have space as their element.

...a human being not only can choose but... he must choose... for in this way God retains His honor while at the same time has a fatherly concern for humankind. Though God has lowered Himself to being that which can be chosen, yet each person must on his part choose. God is not mocked. Therefore the matter stands thus: If a person avoids choosing, this is the same as the presumption of choosing the world.

The truth is lived before it is understood. It must be fought for, tested, and appropriated. Truth is the way... Anyone will easily understand it if he just gives himself to it.
