Thanks to my friend J.W. Wartick ⋅for this one:
I’ll forego the preliminaries here and just say it: this is the best introductory apologetics book in regards to the historicity of the Gospels I have ever read. If you are looking for a book in that area, get it now. If you are not looking for a book in that area, get it anyway because it is that good. Now, on to the details.
Cold-Case Christianity by J. Warner Wallace maps out an investigative journey through Christian history. How did we get the Gospels? Can we trust them? Who was Jesus? Do we know anything about Him? Yet the way that Wallace approaches this question will draw even those who do not care about these topics into the mystery. As a cold-case homicide detective, Wallace approaches these questions with a detective’s eye, utilizing his extensive knowledge of the gathering and evaluation of evidence to investigate Christianity forensically.
He begins the work with a section on method. He argues that we must learn to acknowledge our presuppositions and be aware of them when we begin an investigation. Like the detective who walks into a crime scene with a preconceived notion of how the murder played out, we can easily fall into the trap of using our expectations about a truth claim to color our investigation of the evidence for that claim. Learning to infer is another vastly important piece of the investigation. People must learn to distinguish between the “possible” and the “reasonable” (34ff). This introduction to “abductive reasoning” is presented in such a way as to make it understandable for those unfamiliar with even the term, while also serving as great training on how to teach others to reason for those involved in apologetics.
Chapter 3, “Think Circumstantially” is perhaps the central chapter for the whole book. Wallace notes that what is necessary in order to provide evidence “beyond a reasonable doubt” is not necessarily “direct evidence.” That is, direct evidence–the type of evidence which can prove something all by itself (i.e. seeing it rain outside as proof for it actually raining)–is often thought of to be the standard for truth. Yet if this were the standard for truth, then we would hardly be able to believe anything. The key is to notice that a number of indirect evidences can add up to make the case. For example, if a suspected murderer is known to have had the victim’s key, spot cleaned pants (suspected blood stains), matches the height and weight a witness saw leaving the scene of the crime, has boots that matched the description, was nervous during the interview and changed his story, has a baseball bat (a bat was the murder weapon) which has also been bleached and is dented, and the like, these can add up to a very compelling case (57ff). Any one of these evidences would not lead one to say they could reasonably conclude the man was the murderer, but added together they provide a case which pushes the case beyond a reasonable doubt–the man was the murderer.
