Why Should I Believe Christianity?
Good question! I offer my answer, over eight chapters and a couple of hundred pages, in the second volume of the recently launched Christian Focus series, The Big Ten: Critical Questions Answered. The new book — ingeniously titled Why Should I Believe Christianity? — is basically an introductory exposition and defense of the biblical Christian worldview, but with some distinctive features (on which, see below). In this post, I’ll summarize the content of the book for anyone who might be interested to read it or give it to a non-Christian friend.
Chapter 1 (“Why Believe?”) considers the general question, Why should I believe anything at all? Simply put: we should believe something if it’s true, and we generally determine whether something is true by way of reasons (which can take different forms). We should aim to have beliefs that are objectively true, rather than beliefs that are (say) comfortable, desirable, or fashionable. The chapter also briefly addresses the epistemological cul-de-sacs of relativism and skepticism.
Chapter 2 (“The Big Picture”) seeks to explain why Christianity should be evaluated as an entire worldview: as a comprehensive, integrated, self-contained, self-defining perspective on everything that exists and matters to us. I explain what a worldview is, why worldviews matter, why only one worldview can be true, and how we can apply four ‘tests’ for evaluating worldviews in order to identify that one true worldview.
Chapter 3 (“Christianity as a Worldview”) sets out a summary of the Christian worldview along familiar lines: God, creation, mankind, fall, revelation, salvation, and consummation (“the final chapter”). One of my aims here is to explain the biblical worldview in ‘ordinary’ language (as far as that’s possible!) and in a way that communicates the internal coherence of that worldview.
Chapter 4 (“God is There”) makes a case for the central tenet of the Christian worldview — the existence of the personal creator God of the Bible — based on six features of our everyday lives that we all take for granted: existence, values, morality, reason, mind, and science. I also suggest that while God’s existence can be demonstrated through reasoned arguments, such arguments aren’t necessary in order to know that God exists, because his existence is plainly evident from his creation (Romans 1:19-20).
Chapter 5 (“God is Not Silent”) contends that if a personal creator God exists then he would speak to us, and that God has in fact spoken to us through the prophetic scriptures of the Old and New Testaments. (You’ll have to get the book to find out how I make that argument!) Along the way I explain why, when it comes to divinely inspired scriptures, we should favor the Christian view over the alternative views of Judaism and Islam. I close out the chapter with an appeal to the ‘expert’ testimony of Jesus.
Chapter 6 (“God With Us”) focuses on the true identity of Jesus. Here I make a fairly traditional case for the deity of Christ, appealing primarily to his own testimony and that of his disciples, but also drawing on other confirming evidences. One feature of the argument is that it connects the incarnation with the other tenets of a Christian worldview, highlighting again its inner coherence. The chapter finishes by addressing a common objection, namely, that a divine incarnation is logically impossible and therefore can be dismissed regardless of the supposed evidence.
Chapter 7 (“Defying Death”) explains why Christians believe in the resurrection of Christ and how that essential article of the Christian faith fits into the broader biblical worldview. After dealing with some common objections to miracles, I argue that it’s reasonable to believe in the resurrection and unreasonable to accept any of the various naturalistic alternatives.
Chapter 8 (“What Now?”) ties together the various threads of argument in the preceding chapters and leaves the unbeliever with a challenge: If not Christianity, then what? There must be some worldview that corresponds to reality and makes sense of our experiences of the world. If it isn’t the Christian worldview, which worldview is it? There’s certainly a fence between Christianity and its competitors, but it isn’t one you can sit on.
