Tim Keller is a Lean Mean Book-Making Machine

          That's all I can say. After releasing the bulky and award-winning Center Church, the insightful Every Good Endeavor and the rave-reviewed The Meaning of Marriage (which he co-authored with his wife), we're already seeing another book trailer from Tim Keller?

          You can read an excerpt of his new book, Galatians for You, here. Keller's works are usually very expository and communicative, so this could be a great commentary on the epistle. 

          The trailer is below. Like I said, he's a lean mean book-making machine.
