Jesus: Apocalyptic Prophet of the New Millennium (1999)
How Jesus Became God (2014)
If I was going to recommend three books to newcomers to the field of historical Jesus studies, it would be these three. Ehrman is an interesting guy. He rejected the Christian fundamentalism of his youth to become a secular Bible scholar writing in the academic mainstream. An engaging writer and teacher, he has perhaps done more than any other writer of our time to bring the insights of modern Bible research to a wider audience.
