I'm receiving 300 to 500 letters every week from people telling me that God used my stories to save their marriage or to introduce them to Christ or to heal a relationship that had been broken.
These are very subtle things, of course, and I don't expect everyone to pick them up consciously, but I think that there is something there that you must be able to feel, there is an energy at work that I must trust my audience will be able to pick up at some level.
