For all the Mark Driscoll readers/listeners out there, christianaudio.com offers his book – Religion Saves: And Nine Other Misconceptions – as the FREE audio download of the month (courtesy of Mark and Crossway Publishers). While I disagree with various (significant) theological positions which Mark holds, he nonetheless is a brother in Christ who is determined to impact this world for the glory of Jesus Christ. I look forward to reading (or in this case, listening to) this FREE resource. 
Blessings,
Shannon
