Book excerpt: It can no longer be assumed that most people--or even most Christians--have a basic understanding of the Bible. Many don't know the difference between the Old and New Testament, and even the more well-known biblical figures are often misunderstood. It is getting harder to talk about Jesus accurately and compellingly because listeners have no proper context with which to understand God's story of redemption. In this basic introduction to faith, D. A. Carson takes seekers, new Christians, and small groups through the big story of Scripture. He helps readers to know what they believe and why they believe it. The companion leader's guide helps evangelistic study groups, small groups, and Sunday school classes make the best use of this book in group settings.
