The Bible continues to be the world's bestselling book – but it isn’t the easiest book to just dive into. John Dickson’s forthcoming book A Doubter’s Guide to the Bible: Inside History’s Bestseller for Believers and Skeptics wants to make it easier for everyone – whether Christians or curious doubters – to find their way around the Bible. Part II takes us on a whirlwind tour of the whole of the Old Testament – Abraham’s promises, Moses’ laws, Joshua’s wars – and offers a few key concepts for understanding it as a unified story.
