If our task is discover the story which makes sense of all the Bible's complexity, we need an idea of where to start. The Bible is complex, and understanding the big picture is hard. And as a result, many candidate stories are floating around. Many of them are stories I held to unquestioningly as I was reading the Bible.
"The Bible exists to deliver morals, and to make us become moral"
"The Bible exists to teach us the correct things to believe"
"The Bible exists to deliver a pattern for the organization of a church"
