During his last months, I'd hear my grandfather pray to God nearly every night and pleading to live longer. I've just been confused about it ever since then. I'm certain that he had belief that he'd go to heaven, so what's with the pleading? You read stories about how people have endured torture or whatever else and held onto life, yet many of these people are also religious. Why would they put themselves through torture when heaven's waiting for them if they give in?
