Wright writes the following about the Bible, and this passage is fine example of his engaging writing (Surprised by Hope, pp 282-283).
The Bible as a whole thus does what it does best when read from the perspective of new creation. And it is designed not only to tell us about that work of new creation, as though from a detached perspective, not only to provide us with true information about God's fresh, resurrection life, but also to foster that work of new creation in the churches, groups, and individuals who read it, who define themselves in terms of the Jesus they meet in it, who it to shape their lives. The Bible is thus the story of creation and new creation, and it is itself, through the continuing work of the Spirit who inspired it, an instrument of new creation in human lives and communities.
The Bible is not, in other words, simply a list of true doctrines or a collection of proper moral commands--though it includes plenty of both. The Bible is not simply the record of what various people thought as they struggled to know God and follow him, though it is that as well. It is not simply the record of past revelations, as though what mattered were to study such things in the hopes that one might have one for oneself. It is the book whose whole narrative is about new creation, that is, about resurrection, so that when each of the gospels end with the raising of Jesus from the dead, and when Revelation ends with new heavens and new earth populated by God's people risen from the dead, this should come not as a surprise, but as the ultimate fulfillment of what the story had been about all along. (This, by the way, is deep-level reason why the other gospels were not included in the canon. It isn't that they were the really exciting or subversive bits that the early church excluded in the interests of power and control. They were the books that had stopped talking about new creation and were offering a private, detached spirituality instead. The sudden enthusiasm for these other gospels in certain quarters of the Western world in our own day is a token not of the rediscovery of genuine Christianity but of the desperate attempts to avoid it. New creation is far more demanding--though, ultimately, of course, far more exhilarating--than Gnostic escapism.)
Thus, just as the proclamation of Jesus as Lord results in men, women, and children coming to trust and obey him in the power of the Spirit and to find their lives transformed by his saving lordship, so the telling of the story of new creation, of covenant and new covenant, doesn't just inform the hearers about this narrative. It invites them into it, enfolds them within it, assures them of their membership in it, and equips them for their tasks in pursuit of its goal.
