The Andrew Mutch Professor of Historical and Systematic Theology at Gordon-Conwell Seminary near Boston explains that ‘this book is a report and an interpretation of a consultation’ jointly involving the World Evangelical Fellowship and the Lausanne Committee for World Evangelization. It defends two central theses against contemporary naturalism and pluralism: Christian conversion is supernatural and it is unique. Wells surveys the relevant biblical data, selected views from key stages of church history, and applications to would-be converts to Christianity from various other modern religions and ideologies. Periodically, he also interacts with key sociological and missiological debates.
