Only because you personally have decided to believe it all... do you find the notion of a document, some of which is true, some of which isn't, "ludicrous" in other walks of life?

Only if it requires me to devote my intire life to it's teachings. And requires me to believe it fully. And for the record, I'm not Christian. The glaring flaws in the Bible would make it hard for me to devote my life to it. I'm just debating what the definition of a true Christian is.
