Unconscious good influence
There are some people who are good influences. And they are unconscious. We do not always know what they are. There was a Protestant woman in France who was converted by a bishop who had given a sermon on the Blessed Sacrament. She hid in church and found later on that evening that the bishop came back to make a visit to the Blessed Sacrament. She asked to take instructions. His shadow fell upon her, as Peter's did on the sick people. He was genuine; he was true.
