I assume you have never read it then. The Bible talks about God. It does not prove God because you cannot prove God to someone who doesn't wish to see Him.
You would assume wrong then. I was raised as a Christian. Baptised. I was probably one of the most paranoid Christian children in history. I prayed dozens of times a day. I prayed mightily every night for God not to strike me down in my sleep for sins that I might have committed unawares during the day. Sometimes I just couldn't get to sleep at all because I was worried God might still my heart while I slept and send me to Hell. I assumed He was watching me every single second. If I knowingly sinned, I dropped to my knees that instant and begged for forgiveness. God was not an abstract for me. He was real. He was taking a personal notice in everything I did. I took it as a matter of course that he would kill me or send me to hell if I so much as said the word "Heck".
Never assume too much.
I have studied the Bible. But after long and careful consideration, I have concluded that it demonstrates the existence of no deity. And I really, really wish it did. I would much prefer a universe with a deity than one without.
