Justin Taylor posted an interview of T. Desmond Alexander by Andrew Naselli on the topic of biblical theology. Biblical theology has revolutionized my understanding and appreciation of the Bible, and I thought this brief interview was a good introduction to biblical theology. I’m sharing the first part of this interview but encourage you to read the whole thing.

Consider picking up one of Alexander’s books on biblical theology, too. I have The New Dictionary of Biblical Theology on my shelf (it’s really good), and From Eden to the New Jerusalem is on my wish list.

1. What is biblical theology? How does it compare to systematic theology?

For me biblical theology is about understanding how the Bible as a whole should be read so that we can appreciate its message as the Word of God. I’m still a learner as far as this is concerned. What I’ve found to be helpful is discovering themes that tie together the big picture of Scripture. I’ve tried to convey something of this, hopefully in an accessible way, in my book, From Eden to the New Jerusalem. For me, it’s important that Christians grasp the grand story of what God is doing. Through the story, which I take to be historically true, we begin to understand something of ourselves and the world we live in.

It is this story dimension that sets biblical theology apart from systematic theology. While I think that there is an important place for a systematic understanding of what we believe, it is through Scripture that God speaks to people as they grasp the biblical metanarrative. Hopefully, good biblical theology sheds valuable light on how we should read the Bible. For this reason, I think biblical theology is exceptionally important.

2. Briefly sketch out an example of addressing a theme with a biblical theological approach (e.g., temple, throne of God, evil, lamb, tree of life, people of God, rest).

I’ve said something about most of the examples you list in my most recent book. So let me pick something that might not seem so obvious: the great city.

Fundamental to my understanding of biblical theology is the idea that God created this world with the intention that it should become his dwelling-place, a temple-city filled with people who love and serve him (as reflected in Rev. 20-21). This was the original creation plan. Adam and Eve’s betrayal of God threw the grand design into chaos. Created with the skills to be city-builders, humanity set about building god-less cities. Exhibit number one is obviously Babel. However, in Hebrew Babel is also the name for Babylon. Interestingly, the building of Babel/Babylon is associated with Nimrod in Genesis 10, who is also responsible for the building of Nineveh in Assyria. As a mighty hunter “˜against God’ (not “˜before God’) Nimrod is the founder of a city/kingdom that opposes God’s city/kingdom. Remarkably, the story in Genesis to Kings ends with what appears to be a victory for Nimrod’s descendants (the Assyrians and the Babylonians). The city of God, Jerusalem, is sacked, God’s house is destroyed, and the royal line through which the nations are to be saved is exiled.

Yet all is not lost, for the story does not end here. This big picture is important because it reveals how deep-seated aspirations to create human empires oppose what God desires. Obviously, the OT has lots to say about this (e.g., Habakkuk, Daniel). However, the NT picks up the same contrast. For example, the author of Hebrews has something important to say about the city of God, starting with Abraham. Likewise, the book of Revelation draws an important contrast between the here-and-now Babylon and the future New Jerusalem.

I hope that this very brief biblical-theological sketch of the city makes sense. We’re only scratching the surface. Yet it is a theme that pervades the whole of Scripture….
