Since the late 1970s, there has been a spread of Islamic fundamentalism or Islamist ideology promoted and sponsored by Saudi Arabia and other Gulf states. More than a billion people are following the religion of Islam worldwide. Islamic fundamentalism or Islamism has helped radicalise a small portion of the Muslim population in every region, and a smaller subset has joined terrorist groups and engaged in acts of terror. Yet the Church of Christ must take the gospel to these people in obedience to the Great Commission of Jesus Christ in Matthew 28:18-20. Today, most people actually know very little about Islam and its extreme cultural threat to everything they hold to be good and right and true. The conflict between Islamism and the rest of the world will continue to dominate headlines, define foreign policies and give new urgency to the mission of the Church of Christ. But there is lack of knowledge. “My people are destroyed for lack of knowledge.” (Hosea 4:6) It is for that reason this book is beaming light on darkness, which is ignorance of the battle for the soul of Africa and indeed, the world. It presents ideas, history, and desires of Islam through the lens of a biblical worldview perspective. It is to equip ordinary Christians from all walks of life to minister scripturally and wisely in a world where the conflict between Islam and civilisation is all too obvious.
