Just after his resurrection, Jesus appeared to a couple of his disciples on the road to Emmaus, and began to explain to them—from Moses and all the prophets, how every story in the Old Testament had been about him. He was trying to give them confidence that he really was who he had told them he was.
You might think that the resurrection itself was enough proof. But evidently Jesus believed it would be even more convincing to show them that every single page of a book written by more than 30 different authors over the space of 1,500 years had consistently told one story, and it was all about him.
We don’t know exactly what he said that day, but I imagine it would have sounded something like this:
In Genesis, I was the Word of God, creating the heavens and the earth.
In Exodus, I was the Passover Lamb, whose blood was sprinkled on the doorposts of your heart so that you could escape the bonds of slavery.
In Leviticus, I was the temple, the holy place where you met with God.
In Numbers, I was your ever-present guide, your pillar of cloud by day and pillar of fire by night.
In Deuteronomy, I was the prophet coming who is greater than Moses.
