Chapter 1 is an exposition of Exodus 19. The emphasis is on God who displays himself as present in a spectacular revelation.
This chapter offers a history of how and why the Gospel Coalition was formed. At first it wanted to identify and strengthen the confessional foundation of evangelicalism, and so produced a confessional statement of its own that it discusses herein.
The Introduction encourages readers to think about the nature and value of biblical exposition. It provides answers to three basic questions about biblical exposition: What?, Why?, and Where?
Chapter 1 is a consideration of the theme of preaching Jesus and the gospel from the Old Testament. The author develops his theme by reflecting on John 5:31-47. In this text the importance of Scripture as a witness to the mission of Jesus Christ is unfolded. John refers also to other witnesses: John the Baptist, Jesus’ own works, and the Father. The author continues with a defence of the Old Testament as part of the Christian canon.
