People who really reaLLY need God?

I'm agnostic. I don't trash or attack anyones religion, I just don't know. People say "my life was turned around when I accepted Jesus" or "Allah's will must prevail" or "the way of Buddah brings enlightenment" but truthfully, I don't see any difference in the way people live. I don't see supernatural help, I don't see a blueprint to get to Heaven, or even a reasonable indication that there is such a place. I don't see anyones life on earth made easier, just no difference whatever path you follow. What do I do if I just can't beleive? Them I'm told I don't beleive hard enough. How does one believe harder?
