Os Guinness argues that the greatest challenge facing our world is how we live with our deep differences, especially when those differences go to the very heart of who we are. In this series, we’ll explore some of the most serious manifestations of these deep differences, as well as the cultural strategies employed by secular leaders to answer this global challenge. Finally, we’ll talk about how the Christian doctrine of the Trinity offers perhaps the most fulsome picture of unity and diversity. This episode examines the challenge of diversity through the lens of religious extremism. Though sobering, no serious discussion of diversity will overlook this crucial issue.
