A new study has been done indicating that prayer doesn't help patient's recovery after heart bypass surgery. In fact those that received prayer seem to have more complications.
What the article on this doesn't account for is which God they were praying to. Was it the Christian God? Allah? Great Spirit? Dionysus? Ring Element of the Fourth Water Spirit of Eternia? Lemmy?
I was always taught that God does answer prayers, but a lot of times he'll say no. That was my parochial school's explanation for why the retarded kid wouldn't miraculously turn normal.
