A man who knew empirically that an event had been caused by his prayer would feel like a magician. His head would turn and his heart would be corrupted. The Christian is not to ask whether this or that event happened because of a prayer. He is rather to believe that all events without exception are answers to prayer in the sense that whether they are grantings or refusals the prayers of all concerned and their needs have all been taken into account...We must not picture destiny as a film unrolling for the most part on its own, but in which are prayers are sometimes allowed to insert additional items. On the contrary; what the film displays to us as she unrolls already
contains the results of our prayers and all our other acts. There is no question whether an event has happened because of your prayer. When the event you prayed for occurs, your prayer has always contributed to it. When the opposite event occurs, your prayer has never been ignored; it has been considered and refused for your ultimate good and the good of the whole universe.(For example, because it is better for you and for everyone else in the long run that other people, including wicked ones, should exercise free will than that you should be protected from cruelty or treachery by turning the human race into automata.) But this is, and must remain, a matter of faith.
