Christianity Today is out with what it considers "The Top 50 Books That Have Shaped Evangelicals: Landmark titles that changed the way we think, talk, witness, worship, and live."

These are books that have shaped evangelicalism as we see it today—not an evangelicalism we wish and hope for. Books that have been published since World War II—not every book in the history of Christianity. Books that over the last 50 years have altered the way American evangelicals pray, gather, talk, and reach out—not books that merely entertained.We asked dozens of evangelical leaders for their suggestions, and they sent in their nominations. Then we vigorously debated as a staff as we ranked the 50 books. (We're still debating.)

Coming in at number one: Prayer: Conversing with God by Rosaland Rinker; number two, Understanding Church Growth by Donald MaGavran; and number three, Mere Christianity by C.S. Lewis.

Surprisingly--or perhaps not--mega-selling The Purpose-Driven Life by Rick Warren came in at forty-two and the Left Behind franchise by Jerry Jenkins and Tim LaHaye came in at thirty-six.

So, what do you believe should be the number one book?

Here are the top ten books that have influenced my life.
