I’ve read several of Mark A. Noll’s books, and he is a thorough and honest scholar and historian. Turning Points is one of his best books, in my opinion, because more than any other book he’s written, he sweeps through Christian history and shows why certain points in history, these “turning points,” are important. Two examples of turning points: church councils and the nailing of the 99 Theses on the wall of Wittenberg by Martin Luther. He explains why these things are important. It has been many years since I read the book, but I judge good books by their ability to stick to the ribs of my brain and never let go.
