25years has great points as always. Not to start a religious debate, but A LOT of religious people have the notion that God is somehow involved in their pain, and that they are lowly sinners that deserve the worst - it's in their book. How someone maintains adequate self-esteem when their book tells them they're a lowly worm, worthy of death, I'm not sure.
Whatever your beliefs, to rely on a supernatural diety to fix your sitch is foolish - you fix it, as best you can. If there are things beyond your control, and there are, you must forget them. Same thing for the past.
