Of all the stupid ideas that religion is responsible for, praying is surely the msot stupid of all. Do you seriously believe that an omnipotent being decides on a seemingly random basis whether to intervene in the trivialities of human existence? So if he answers your prayer for a new job or to get well, why would he ignore those of people dying in Haiti or wherever? Seriously, think about it for a while.
Not claiming it as evidence, just offering my viewpoint. I dont sit every night and pray for a lottery win. When my son was born however, and he had breathing difficulties i found myself praying that he would get better. On that occassion, like many others it worked out well for me. Not saying it was a result of divine intervention but it was the only thing i could do and from that i took some small comfort. It was an instinctive thing and i believe it is something that millions of people around the world do. Was just trying to give an insight into what it is like to be a believer.
