Biblical theology is essential if we’re going to feel the Bible’s own pulse and follow its unfolding plot. Without it, systematic theology can easily succumb to a deductivist scheme. Going back to the street-map analogy, it’s easy to deduce where roads must go because of the map even if they don’t! Yet it can never be used as a rival of systematic theology. Christ was not only crucified and raised; he was “crucified for our sins and was raised for our justification.” Doctrine arises from the drama, indicating the significance of God’s acts in creation, redemption, and consummation.
