Truth's Independence and Winsome Confidence

Christians should be persuasive, and with his new book Fool's Talk, Os Guinness offers a comprehensive presentation of the art and power of creative and distinctly Christian persuasion.

How should this desire to be persuasive affect our evangelism? Does God expect us to know the answers to every question? And how can we do this while remaining humble, recognizing that salvation is all of grace?

For our most recent 9Marks interview, Mark Dever sits down with Guinness to talk with him about these questions and more. We hope you'll find it useful.
