In Shooting Back: The Right and Duty of Self-Defense, Charl van Wyk makes a biblical, Christian case for individuals arming themselves with guns, and does so more persuasively than perhaps any other author because he found himself in a church attacked by terrorists. It instantly became a South African bestseller, as well as a bestseller for WND, which imported thousands of copies of the original book for sale online to audiences in the United States and around the world.
