STR is running a deal on a Common Ground book/audio combo. Bought separately, the items cost $20.94. Special price currently: $15.95. Audio is available in CD and in mp3.
The audio includes two presentations of about an hour each…the first roughly follows the first three chapters of the book, but adds a Biblical defense of common ground (not in the book)…the second roughly follows the remainder of the book, focusing on specific areas of common ground on abortion.
