This month ChristianAudio.com has Just Courage by Gary A. Haugen for free. Here is the description of the book from their website:
International Justice Mission president Haugen has found that “the pathway out of a nearly comatose state of boredom, ineffectiveness and triviality lies in the struggle for justice.” This book describes how to break out of a ho-hum Christian life and see God’s powerful and mysterious ways at work.
