This is an age where Christianity is no longer the assumed foundation of culture. Instead, secularism, relativism, and individualism shape how people think, live, and even approach faith. Many within the church have unknowingly embraced a shallow, self-focused spirituality that offers comfort without transformation. How can the church recover a robust, life-giving vision of discipleship in such a world? With a little help from C. S. Lewis, this book offers a way forward. Lewis's insights--rooted in reason, imagination, and community--speak powerfully to this modern crisis, equipping believers to engage both mind and heart. Through cultural analysis and biblical wisdom, this book calls the church to rediscover discipleship as an intellectual, imaginative, and relational pursuit--one that forms resilient, thoughtful, and deeply rooted followers of Christ. Whether picked up by a pastor, church leader, or everyday disciple longing for deeper faith, this book will challenge and inspire readers to cultivate a Christianity that is not only true but beautiful and compelling in an increasingly post-Christian world.
