Book excerpt: 2011 Christianity Today Book Award winner! Alister McGrath, one of the most prominent theologians and public intellectuals of our day, explains how Christian thinking can and must have a positive role in shaping, nourishing and safeguarding the Christian vision of reality. With this in our grasp, we have the capacity for robust intellectual and cultural engagement, confidently entering the public sphere of ideas where atheism, postmodernism and science come into play. This book explores how the great tradition of Christian theological reflection enriches faith. It deepens our appreciation of the gospel's ability to engage with the complexities of the natural world on the one hand and human experience on the other.
