J.D. Greear has a new book coming out this October called GOSPEL: Recovering the Power that Made Christianity Revolutionary (foreword by Tim Keller).  This book comes in the wave of great books coming out in recent years on the gospel in what I believe to be a work of God in bringing us to recovery and renewal in and through the good news of Jesus Christ.  Below is a little video of Greear explaining how God is the central figure in the gospel story, followed by a little trailer where Greear explains why he wrote his forthcoming book.
