On this special edition of the White Horse Inn, Michael Horton talks with Os Guinness about pursuing civility in a Post-Christian culture. How are we best to make our case in the public square? In what ways have Christians failed as they have attempted to do this in recent years? Os is the author of numerous books on faith and culture, such as Dining With the Devil, Time for Truth, and The Case for Civility, And Why Our Future Depends on It. (originally aired 02-15-09).
