In 2012 I was in the Dominican Republic helping to rebuild a church when I got into a discussion about whether we really needed the Old Testament. I tried to defend the OT by arguing that the NT by itself would be like a childrens’ coloring book, with all the shapes drawn but with no color to fill in the pictures to get all the fullness of the biblical picture of God and his purposes. I also pointed out that many heresies likely would arise without the OT to guide us in our understanding of God. Well, John Goldingay has done away with a defensive strategy and he’s gone on the offense. He flips the common question of whether we need the OT on its head and asks: Do we really need the New Testament?…
