I got this in the mail from Zondervan this week. Whenever they issue a new printing of a book you write they send you a new copy of your book along with a note of congratulations. This time the note said,"A copy of the 6th printing of your book, Exponential is enclosed." Wow, I'm extraordinarly grateful that this book Jon and I published just 2 years ago is already in in it's 6th printing. Exponential simply tells the story of how Jon, myself and some friends were able through God's power to start a reproducing church movement while explaining how you can do it too! If you haven't got a copy, you can order it HERE.
