The story of Scripture, then, is all about God’s King and his gracious rule and reign; it’s all about the forgiveness of sins that King has won for his people, who hail from every tribe and tongue and people and nation. The whole story of the Scriptures, rightly understood, focuses on Jesus Christ from beginning to end.
-Roark & Cline, Biblical Theology, p. 26

Biblical theology is not just an interesting topic. It informs who we are and how we live. It’s a way of getting out of a false world into the real one, a transporter enabling us to inhabit the story of the Scriptures. The Bible is the real Hitchhiker’s Guide to the Galaxy, and biblical theology is the Heart of Gold that improbably moves us into the real world. We engage in biblical theology so as not to misinterpret what happens to us, seek our identity in the false world, and waste our lives.-James Hamilton Jr, What Is Biblical Theology?, loc 902
