If I were to build a case for why someone should believe Christianity, this is probably the way I would do it. Anderson begins by laying out some rules of engagement. He is not going to assess particular propositions, but instead take entire worldviews and assess them on consistency with the world around us and internal consistency. Along with some other criteria, he then begins to briefly assess the major worldviews on offer.
Firstly, a Christian worldview is outlined. As usual, Abraham doesn’t get mentioned once (disappointing)! Atheism is rejected based on the traditional arguments for God (Ontological, Cosmological, Teleological. The big names are impressive, aren’t they?). A personal God is then determined to be necessary, so all non-personal philosophies about God are rejected (Buddhism of all kinds, Hinduism, new age). We are left with Judaism, Christianity, and Islam. I forget why exactly, but Judaism and Islam are rejected. Looks like it only makes sense to be a Christian.
Anderson then goes on to discuss some particulars about Christianity, including sin and the necessity for forgiveness. Would I recommend this book? It’s good for a teenager to gain exposure to this type of discourse, but I probably wouldn’t recommend it.
