He is emphasising the incredible value of what is in the Christian bible.
No other book provides in-depth answers to these four fundamental questions which every human being asks at some point in their lives:
Where did I come from?
Who am I?
Why am I here?
What is my destiny?
I have to say how sorry I feel for people like yourself Alan I can't imagine how it must feel to allow yourself to believe in so many unsupportable bronze age mythical stories, all tied up in one book, I couldn't let myself live in or by such a regressive way of thinking.
It's not like you or anyone else will ever be able to quantify these beliefs as they slowly but surly fade away to join all of the other old beliefs like Zeus, Thor Ra etc etc; why waste your time on them only there's nothing that has ever been found to date that has shown the slightest hope of proving the case that this deity of your imagination really exists, nor is it likely to happen either, the odds are certainly not in favour of anyone finding proof, bit of a lost cause Alan.
