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.
