It is of first importance to recognize that the biblical story embraces all of reality, namely God and the realm of creation. While it focuses on only certain aspects of reality, the whole is represented either directly or indirectly. The created realm is in turn shown to have its pinnacle in the human race. Only human beings are described as created in the image of God and as having dominion over creation. . . . When Adam and Eve sinned, the entire universe fell with them (Gen 3:17-19; Rom 8: 18-23). Redemption has its goal in a new race of humans and a new creation. Sin fractured all relationships except those within the Trinity. Redemption in Jesus Christ puts the universe back together again as a new creation. How is this achieved? The gospel shows us that it is done in a way that involves the promise of new things (the bulk of the Old Testament), the representative restored reality in the actual person of Christ, and the summing up of all things in Christ and the consummation.
. . . Jesus is thus the representative new creation. . . . Christology in the New Testament shows Jesus to be the comprehensive expression of reality in the purpose of God. The notion of the cosmic Christ rightly applies to the incarnate Son because he is representative reality.
