I am Agnostic, and I believe that it is just used for moral support, and encouragement. I think it gives people something to live for.I also believe that things happen for a reason. Maybe you didn't quite fulfill what G-d had in mind for you, and he decided to let you live.I don't know, but I was raised that if we knew, we would be G-d.I know a lot of what I just said conflicts itself...but I am still trying to find the "Right" religion for me.
