Islam is making a significant mark on our world. It is perhaps the fastest-growing religion in the world. It has become a major obstacle to Christian missions. And Muslim terrorists threaten the West and modern democracies.What is the history of Islam? What do Muslims believe? Do Christians and Muslims worship the same God? Why do we have this clash of civilizations? Is sharia law a threat to modern democratic values? How can we fight terrorists in the 21st century?These are significant questions that deserve thoughtful answers. This book provides practical, biblical answers so Christians can understand Islam, witness to their Muslim friends, and support efforts by the government to protect all of us from terrorism.
