There is something missing from our arsenal as Christian apologists. I came upon this truth about a year and a half ago, but have only begun to realize how much we have been missing. Let me begin with an illustration:
It was a short, scenic drive down Interstate-94 to meet with Dr. Timothy McGrew, a professor of philosophy at Western Michigan University. At the time I was living in Ann Arbor, and I had only conversed with Tim on Facebook. He told me, with ill-concealed glee, about a folder on his computer that was filled with PDF scans of copyright-free (public domain) books by forgotten Christian apologists and theologians. The arguments in them, he told me, were not often used by modern apologists and could but increase my knowledge.
We met at a restaurant along the highway and talked for about an hour and a half while Tim uploaded files on my computer. Tim described to me a number of the items in this collection, but what struck me was how many arguments he referenced which are simply forgotten in current apologetics discussions. For example, he described the argument from “undesigned coincidences,” which basically goes through the Bible and shows how interrelated texts confirm each other’s historical veracity. I was shocked that I had not run into such a profound argument for the Christian faith. I was tremendously excited to find out that there were many such treasures waiting to be discovered.
