“There never yet have been, nor are there now, too many good books.”

Almost five centuries later, Martin Luther’s words still ring true today. At The Gospel Coalition we seek to renew the contemporary church in the ancient gospel of Jesus Christ. We’re grateful for how God has used good books to strengthen his people in past generations, and we’re committed to promoting gospel-centered resources today.

That’s why, as we celebrate the 500th anniversary of the Protestant Reformation, we’re excited to partner with Zondervan for a TGC17 eBook sale. You can save up to 76 percent on timely and popular works by Timothy Keller, D. A. Carson, Michael Horton, and many others.
