You are in a Bible study, with a group of people. You are all studying the same passage. And someone points out something that you hadn't noticed before. New light is suddenly shed on familiar material. And you realize that, left to yourself, you'd have missed that. Other people help us understand both Scripture and our faith more deeply. It helps to study Scripture and think about the gospel in good company -- and this book aims to put you in good company as you think through some key areas of the Christian faith. Reading about the great Christian thinkers of the past is like being at a really good Bible study. They can help you think through things you may have been puzzled by. They can cast new light on a familiar scriptural passage. They can inspire with their testimonies. They can stretch your thinking, helping you wrestle with important questions which you ought to think through at some point. What better way to begin, than to be introduced to a classic discussion of such questions? --from the Introduction
