In this book, the second in the Heart of Christian Faith series, Alister E. McGrath provides an exploration of how we can best understand God using analogies, illustrations, and stories. This short, accessible guide also provides a pastoral and spiritual consideration of the difference that our belief in God makes to the way in which we think about ourselves and our world. With future volumes to examine other core Christian principles, McGrath's new series will define "mere Christianity" to a new generation for many years to come.
