Michael Spencer at IMonk responded to someone's question about the centrality of Jesus and whether or not we're missing something more by putting so much focus on God in the flesh.
My answer is simple: Whenever we want to know about the nature and will of God, we can find it in the life of God as man in Jesus.
Our very canon, in the most simplistic terms, is based on the authority of Jesus: He verified the voice of God in the OT; the gospels are sacred because they are about his life, death, and ressurection; the rest of the NT is accepted primarily because of the suspected authors' relationship to the Man and the new body of believers He built. Study whatever you wish in the Bible -- past, present, and future things -- and it all points to Jesus. He is the Word, and He is the fulfillment of the Word. This, I believe, was the very message of John 1.
I've ranted in the past about theologians who impose an unfair interpretation grid over the Bible, particularly those grids which begin with an eschatological view. The only right grid, IMO, begins and ends with Jesus. If it's not all about him, we have not put the same weight into the centrality of Jesus the Bible does if read from cover to cover without any bias whatsoever.
