The beloved Chronicles of Narnia are only the "top layer" of the rich treasure trove of C.S. Lewis's writing. This brilliant Oxford don made a tremendous impact on contemporary Christian thought and has deeply influenced generations of followers of Jesus in the half-century since his death. The authors in this collection examine Lewis's many contributions and reflect deeply on their significance for theology, spiritual imagination, and the challenge of Christian discipleship today. From Narnian adventures to Screwtape's letters, through studies of Lewis's collaborators (like J.R.R. Tolkien) and inspirations (like George MacDonald), and by way of reflection on deeper theological themes like human will, joy, and the End of Days, this book will inspire and provoke contemplation of God's presence in your life and in our world.
