Quote from Tim Keller’s Chapter in “The Scriptures Testify About Me”:

If there is one Old Testament passage that the New Testament invites us to read in a Christ-centered way as a paradigm of Christ’s salvation, it’s the exodus.

I’ll never forget nearly forty years ago sitting in R. C. Sproul’s living room in Stahlstown, Pennsylvania. Alec Motyer, a British Old Testament scholar I had never heard of, was visiting. I was on the floor with a bunch of other college and seminary students, and Sproul said to Motyer, “Tell us about the connection between the Old and New Testaments.” Motyer replied something like this:

Think about it. Think of what an Israelite would say on the way to Canaan after passing through the Red Sea. If you asked an Israelite, “Who are you?” he might reply, “I was in a foreign land under the sentence of death and in bondage, but I took shelter under the blood of the lamb. And our mediator led us out, and we crossed over. Now we’re on our way to the Promised Land, though we’re not there yet. But he has given us his law to make us a community, and he has given us a tabernacle because we must live by grace and forgiveness. And he is present in our midst, and he will stay with us until we arrive home.

Then Motyer added, “That’s exactly what a Christian says—almost word for word.” And my twenty-three-year-old self thought, “Huh.”

What can we learn from the Red Sea crossing about Jesus and our salvation? Three lessons: salvation is about getting out, but it’s about

what we’re getting out of: bondage with layers;
how we’re getting out of it: crossing over by grace;
why we can get out of it: the Mediator.

That’s how the story of the exodus connects with the rest of the Bible. We would not make these connections without the rest of the Bible, but the connections are clear when we look at the Bible’s sweeping story line.
