The Last Christian on Earth: Uncover the Enemy’s Plot to Undermine the Church

In one of the world’s great ironies, the Christian faith contributed decisively to the rise of the modern world, but has been undermined decisively by the modern world it helped to create. The Christian faith has become its own gravedigger. In the 25 years since philosopher and social critic Os Guinness first published The Gravedigger Files, much has happened: the fall of the Soviet Union, the rise of the computer age, the reemergence of China and India, the rise of Islamic terrorism, and the worldwide revitalization and politicization of religion. The central mystery of Dr. Guinness’s spy novel inspired by his affection for John le Carré thrillers remains unsolved: Can Christians regain the full integrity of faith in Christ while fully and properly engaged in the advanced modern world? This new edition of The Last Christian on Earth, which includes previously unpublished top-secret memos, is Dr. Guinness’s parable about the future of the Christian church in the West. Written in the grand tradition of le Carré, Fleming, and Clancy, this thriller pays homage to the genre while transcending it–because the real-life ending has yet to be written!

The buzz among evangelicals today is about relevance and reinvention, about new ways of “doing church” through revising, innovating, borrowing, mixing, and experimenting. Yet, says Os Guinness, in our uncritical pursuit of relevance, Christians have actually become irrelevant. By our determined efforts to redefine ourselves in ways that are more in line with the modern world than are faithful to Christ, we have lost not only our identity but our authority and significance. Prophetic Untimeliness addresses this issue by giving practical, constructive solutions for living with integrity in the midst of modern pressures. Guinness explores what it means to be both faithful and relevant, and how to be truly relevant without being trivial or trendy. Readers will be challenged to develop “resistance thinking,” an approach inspired by C. S. Lewis that balances the uncomfortable truths of the gospel with the pursuit of relevance. Only by being true to Christ and living with integrity and wisdom will we meet the needs of a world that is hungry for some really good news.

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.

For decades Os Guinness has been one of the most nuanced, realistic, yet hopeful voices calling Christians to engagement with culture. This latest volume from him should not be missed by anyone. Os summarizes some of the most helpful recent discussions, updates many of his own lifelong challenges to the church and provides many fresh insights. Highly recommended.
