To evoke angels . . . we need only to live in quiet expectation of their presence and attune ourselves to their heedings. . . . From time to time, angels conceive and bring about serendipitous experiences and events in our lives to remind us that we are continually in God's care and that we are part of a divinely ordered universe.
