““The essential act of religion … is prayer. Prayer is all-powerful. … God is to [the pious soul] … the immediate, efficient cause of all natural effects. … He has recourse to prayer in the certainty that he can do more, infinitely more, by prayer, than by all the efforts of reason and all the agencies of Nature, - in the conviction that prayer possesses superhuman and supernatural powers. … [A]n immediate act of God is a miracle; hence miracle is essential to the religious view. … [I]n miracle man subjugates Nature … to his own ends[.] … [I]n miracle all things are at the service of necessitous man.””
