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. I conclude the series by talking about the Christian doctrine of the Trinity. Though people often avoid the topic because of its complex nature, it offers the most beautiful and compelling answer to challenge of diversity.
