Peacock, early in his book, New Way to Be Human, speaks of understanding the story of Jesus, as well as our own personal salvation story, as embedded in the context of the OT, and indeed, in so far as we understand it, in the future history of God's creation. Peacock warns of the dangerous subjectivity that occurs when we see our own relationship with God as somehow entirely personal, exclusive of the panoramic narrative of Scripture.
In the past few months I've been reading through the OT and enjoying it immensely. But now I'm starting over. That's because this morning I began reading D. A. Carson's daily devotional, For the Love of God, which is tied to Robert Murray M'Cheyne's Bible reading plan. Carson, in his introduction, says much the same thing as Peacock. "My aim is to show, in however preliminary a way, that reading the whole Bible must stir up thoughtful Christians to thinking theologically and holistically, as well as humbly and reverently."
This is the one I esteem: he who is humble and contrite in spirit, and trembles at my word. Isa. 66:2
