 But it turns out those are some of the most important things I've learned over the years. And this book is a departure for me. If you're familiar with my work, you know that I have described the case for God's existence. And I think this is a robust case that points to the strength of the Christian worldview. That's in a book called God's Crime Scene. I've described the case for Christianity based on the manuscript evidence. That's in Cold Case Christianity. And I've also described the amazing impact of Jesus on culture. Unparalleled impact. That's in Person of Interest.
