Jesus . . . is himself the grand theme of the 'story-line' of both Testaments, the focal-point giving coherence to the total 'picture' in all its complexities. . . .
[T]he OT is Jesus predicted; the Gospels are Jesus revealed; Acts is Jesus preached; the epistles, Jesus explained; and the Revelation, Jesus expected. He is the climax as well as the substance and centre of the whole. In him all God's promises are yea and amen.
