Biblical theology is not just about reading the Bible rightly, though it begins there. It serves to guard and guide the local church. It maintains the right message, defines the task of the messenger, identifies impostors, tells us what we do when we gather, and sets the trajectory of our mission. It answers the question, Who are we, as the church in the world? Those are some of the topics this issue of the Journal will explore. The goal here is not so much to trace out the Bible’s storyline, but to show how knowing that storyline locates the identity and work of the church in the grand sweep of history.
