Taken from Michael S. Horton, Covenant and Eschatology: The Divine Drama. The brackets  are mine.
“Although moderns have made far too much out of central dogmas and termini a quo [I don’t know what the latin phrase is in English, but I will find out, nonetheless, keep reading], there is a irresistable urge to find a significant core of doctrine which all things in scripture point to Christ. This, I think, is suggested by the way in which all things in scripture point to Christ, a hermeneutical principle that Jesus Himself authorizes ( John 5:39-40, Luke 24:13-29). It is not a canon within a canon, but it is a canonical center that Jesus’ identity and mission represents. And yet his centrality cannot be accounted for in the abstract. It requires a context, and that context seems to be shaped in scripture by the notion of covenant. It is not Jesus Christ the healer, as guide, as fellow traveler, as ruler, or a host of other things, that this particular story highlights, although it is true that Jesus was and is all of these. It is Jesus Christ as the mediator of the covenant that occupies center stage and unites the drama of redemption in its Old and New Testament acts.” (18)
