Half A Poison Pill Won't Kill Me: Thoughts on Worldliness and the Media That Promote It: Josh Harris explains, "This booklet features quotes, both from quoted authors and from the speakers in the series—C. J. Mahaney, Bob Kauflin, and myself. We had many requests for these quotes so that our people could continue to be aware of our calling to be 'in the world but not of the world.' We hope it will help you develop and maintain convictions that will allow you to live a life pleasing to God."
