Answering Islam evaluates the claims of orthodox Islam from a Christian point of view, appealing especially to the Qur'an and the Bible. The authors, a Christian apologist and a former Muslim, provide apologetic answers to prepare Christians for ministry in the Islamic context. This second edition contains two new appendices, a new preface written in light of September 11, 2001, and updated information throughout. "This book is a theological masterpiece, the most lucid and comprehensive theological analysis and critique of Islam from a Christian perspective I have ever seen. It is invaluable as a tool for understanding the most serious religious challenge to Christianity in the modern world." R. C. Sproul, Ligonier Ministries
