David Gentiles was the kind of guy who showed up to help people move, always rooted for the underdog, and read his Bible so much that he could fold it like a magazine. Gentiles never wrote a best-seller. He was not a sought-after speaker. No one called him the voice of a new generation of evangelicals. "But if it's true a person's life is a sermon, David Gentiles preached the best sermon I've ever heard," Miller said.
