Religion

There's a reason I gave up on religion. No my mom didn't drive me to the point where i couldn't stand it, no she didn't neglect introducing religion into my life. In fact when I was younger I went to Jehovah Witness meetings with my Great Grandma(Nana), I went to Christian and Catholic Church with my Grandma Gina. I understand there are probably thousands of religions, but the same concept applies to all. I find these rules in life just to get into heaven hard to believe.I'm not stating that the bible is wrong, I STILL have morals. Now I'm NOT attacking religion at all. I'm just questioning all the things in life that make it so simple to go to hell. If there is a god, then please tell me this, why is there rape in the world and why do people murder other human beings? Yes you can say it's because of the devil. Well here's this question, since god is the creator of all things, then why did he create the devil? Why put humans through this pain? I also don't get praying, if God knows everything, then why do you need to prey to him? do you need to prove your allegiance as a follower or something? I'm fully appreciative of my mother in her decision to allow me to form my own opinion on life and religion. No one made me go to church with my grandparents, they simply invited me and i accepted. I was not a child who was dragged and forced to sit in church to hear the preacher. I'm aware I'll probably loose some people as "friends" then again they're not really friends if they simply get mad over religion. And if, thats a big fat if, god exist, I will gladly take my ticket to hell. I ask this, if you're judging me based on my decision, then aren't you doing the job of god? And i ask this from my family, Please do NOT tell Grandma Nana of my decision, I want that very wonderful woman to have a peaceful rest of her life, she deserves it, regardless of what anyone says.
