"When the Bible calls for action it does not refer a man to his own powers but to Jesus Christ Himself. ‘Without me ye can do nothing’ (John 15.5). This sentence is to be taken in its strictest sense. There is really no action without Jesus Christ. All the innumerable different activities which in general assume the appearance of action are, in the judgment of Jesus, as though nothing had been done."
Dietrich Bonhoeffer, Ethics
