From Michael Lawrence’s book, Biblical Theology in the Life of the Church

“The grace of God in the gospel through the sacrificial death of Jesus Christ not only describes the climax of the covenants but the climax of God’s redemptive acts in history.  It also bring us, finally, to the point and center of gravity of the story.  Since this story is the story of redemption, it’s quite easy to fall into the habit of thinking that that the point of the story is me, or us: the people being redeemed.  But that would be a misreading of the story.  Though we benefit immeasurably from this story, the center and point of the story is God and his glory (Eph. 1:6, 12, 14).

This does not mean God is some sort of giant, preening, celestial peacock, impressed with himself in narcissistic obesession.  In fact, the display of God’s glory in Scripture, is filled with irony.  For though God’s glory is seen in his ability to save, that salvation comes only through judgment.  And that judgment is borne by himself, in the person of his own Son.  It is in the cross that God’s glory is seen, in the suffering and sacrifice of him who is most worthy for those who are not worthy at all.

Here is the grace of God, and the glory of God, as he walks through those animals cut in two, as he provides a ram for Abraham’s son, Issac, and as he provides a Passover lamb for the Israelites.  All this that he provided for his people was but a picture and foretaste of his ultimate provision: his one and only beloved Son, Jesus, sacrificed on the cross for sinners, bearing the judgment they deserved, that God’s glory might be displayed in salvatoin and mercy, even as he met the demands of justice himself.”
