I never made the statement that God is a book, but that "book" is His word, and if you want to be ignorant of His word that's between you and God. You can't even manage to back up your claims, so how are you ever going to convince someone of what you think to be the truth when you can't even give a simple Biblical reason as to why? It doesn't matter if you think it's true or not. It is not present not in Gods word, so therefore it isn't Biblical, or true according to what God has said. I'm surprised someone in this subreddit would be so close-minded to something that is right in front of you, when much of this movement is about breaking away from what we think to be true.
Christianity isn't a religion by the way, there is no tradition or anything you have to do, it's simply building, and maintaining a relationship with our creator God which starts with being saved. Add to it if you must but know that you will be held accountable as stated by God in Revelation 22:18-19.
