Renaissance: The Power of the Gospel However Dark the Times
We live in dark times. Christians wonder: Are the best days of the Christian faith behind us? Has modernity made Christian thought irrelevant and impotent? Is society beyond all hope of redemption and renewal?
In Renaissance, Os Guinness declares no. Throughout history, the Christian faith has transformed entire cultures and civilizations, building cathedrals and universities, proclaiming God’s goodness, beauty and truth through art and literature, science and medicine. The Christian faith may similarly change the world again today. The church can be revived to become a renewing power in our society—if we answer the call to a new Christian renaissance that challenges darkness with the hope of Christian faith.
In this hopeful appeal for cultural transformation, Guinness shares opportunities for Christians, on both local and global levels, to win back the West and to contribute constructively to the human future. Hearkening back to similar pivotal points in history, Guinness encourages Christians in the quest for societal change. Each chapter closes with thought-provoking discussion questions and a brief, heart-felt prayer that challenges and motivates us to take action in our lives today.

The American Hour: A Time of Reckoning and the Once and Future Role of Faith
The American Hour is a searching assessment of the strength of the American republic at the end of what has been called the “American Century.” In an incisive analysis, Os Guinness examines the ways in which the current crisis of cultural authority strikes at the heart of American identity. As he shows, this crisis has occurred because America’s beliefs, traditions, and ideals – civic as well as religious – are losing their power to shape the private and public lives of countless Americans. He first charts this growing crisis in America’s moral and cultural order, tracing its roots early in this century to the first open phase of conflict, which began to build in the fifties and climaxed in the cultural revolution of the sixties. He goes on to examine the subsequent conservative counter-revolution, focusing throughout on the impact of this crisis on three areas vital to the health of the republic – on American identity, as in the currently contested notion of what it means to be an American; American public philosophy, including the now controversial relationship of religion and public life; and American republican character, including our distinctive emphasis on the importance of the “habits of the heart.”
Guinness also examines the historical role of religion in American society and its integral function in American public life. He explores how religion came to lose its power as a vital shaping force of America’s moral and cultural order, and he considers the consequences of this loss. He then establishes four scenarios that range from the continued decline of religion in public life to a resurgence of faith, showing how each possible outcome could affect American society in the upcoming century. Examining closely the recent controversies over religion and politics, Guinness concludes by setting forth a vision of how we can move beyond these struggles and provide America’s diverse faiths with a revitalized and constructive role in public life.
