Now comes the fulfillment and relieves him, but soon he is again placed on reconnaissance for expectancy; then he is again relieved, but as long as there is any future for him, he has not yet finished his service. And while human life goes on this way in very diverse expectancy, expecting very different things according to different times and occasions and in different frames of mind, all life is again one nightwatch of expectancy.
