Maybe some people do, but not all Christians. The Bible is not God, I don't have faith in the Bible, nor a relationship with it...
That would be weird. The bible is still essential above all others in that, the more that one wants to know God, and be one in Christ...the more one would need his bible. God is not the book, but you can find God through the book, behind the book, and therein have a relationship with Him.
Why do you think He left us the book? Because it isn't needed? No big deal? It is.
That book contains the very thoughts of our God. In a compact portable reference device. How cool is that?! It's our human owners manual, with everything in it that we could possibly need for any situation in our lives. When you crack open that book, God sits up and takes notice and His Spirit starts moving for us. I can understand wanting to be cautious and not to make the bible something it isn't, Keep a proper perspective though. It's not just another book!
Spirits...be very careful with Spirits. Test all of them, all of the time. If Jesus Himself comes into your room, test Him. He told us to, He will not be offended to be tested. The test is, did Jesus Christ come in the flesh? Anything other than a yes is not of God.
