How to Defend the Christian Faith : Advice from an Atheist [PDF ebook] 
Advice from an Atheist

The first book on Christian apologetics written by a leading atheist figure that teaches Christians the best and worst arguments for defending their faith against attack The Christian faith has been vigorously defended with a variety of philosophical, historical, and theological arguments, but many of the arguments that worked in an earlier age no longer resonate in today’s educated West. Where has apologetics gone wrong? What is the best response to the growing challenge presented by scientific discovery and naturalistic thought? Unlike every work on Christian apologetics that has come before, How to Defend the Christian Faith is the first one written by an atheist for Christians. As a former Christian defender who is now a leading atheist thinker, John Loftus answers these questions and more. He shows readers why Christian apologists have failed to reach the intelligent nonbeliever and offers practical advice for Christians, whether they want to better defend their faith against atheist arguments, or actively convert more individuals to Christianity.
