If you do a Google search for "God," "prophet," and "Charles Darwin," you'll see that I'm not the first to suggest what I'm about to say, that Darwin was a prophet of God. (Luckily, the point of this writing isn't simply to make that claim.) You know how both believers and non-believers are always asking why God doesn't speak to anyone anymore like he did a few thousand years ago? Or those who say that God will reveal more about himself one day, but we'll just have to wait? Those people have obviously never read Charles Darwin.
When Charles Darwin published The Origin of Species in 1859, we learned more about God than we had in hundreds of years. We arguably learned more than we ever had from any other book, sacred or otherwise.
