“Several years ago I gave a talk at Calvin College, about the two-book preaching method that was evolving in my mind and at our church. After I presented, someone came up to me and told me that Calvin Seminary’s Old Testament and Preaching professor, Sidney Greidanus, had been sitting in the back row. I swallowed hard when I heard that news. Dr. Greidanus was my pastor when I was a boy and I knew he held the bar very high when it came to orthodox preaching. That night I couldn’t help but wonder what he thought. The next day, I bumped into him and his wife. I remember thinking, “Well at least his wife is here, he can’t be too mean!” After smiling and greeting me with his deeply resonant voice he said, “I think I see what you are doing. I’ve spent my entire life connecting the Jesus of the New Testament to the Jesus of the Old Testament. You are connecting the Jesus of the New Testament to the resurrected Jesus today.”
Today I woke up with a single thought that bloomed into an outline for chapter two. The bulk of this chapter is going to take what Dr. Greidanus spent his life thinking about (captured in his seminal book, Preaching Christ from the Old Testament ) and reapply it to the context of two-book preaching.
There’s an axiom that theologians and preachers are familiar with, ‘The New is in the Old concealed, the Old is in the New revealed’ (Augustine). Christ, the gospel and the message of grace are already there, in the Old Testament, in a veiled, foreshadowing kind of way. All of the promises, covenants and the laws of the Old Testament find their fulfillment in the Christ of the New Testament.
Can the ways Christ in concealed in the Old Testament illumine a path to seeing the resurrected Christ in his world more?
