Suddenly we move from laws about life in the land to a description of the journey to the land, a description that focuses closely on the company along the way — the mysterious and awesome figure of the Angel of Yahweh. Also, this section is largely taken up with promises instead of demands. How does it fit in the book of the Covenant, which, as we have posited for several weeks now, is largely concerned with the themes of justice and piety? The answer is that justice and piety are only possible through the Mediator. Though the Pentatuech is popularly called "law," and it does indeed contain a number of laws, it is also about the Messiah, the Mediator. It deals with the coming Prophet, Priest, and King who is Yahweh but who is also distinguished from Yahweh—and this is one of the places where it does so. Moses is reminding us that though law is real and important, law exists and is meaningful only in the context of a lawgiver who is a Savior and Mediator. Thus, this passage describes walking with God the place He has prepared, and how it brings enormous blessings but also demands perfect obedience. Talking about Jesus is not some way of talking about how we can be as wicked as we please. Nor is talking about obedience some way of avoiding the glorious Angel of Yahweh and pretending that He has nothing to do with our obedience. Actually, the Christian life, our walk with God, is all about being with Jesus — but being with Him requires perfect obedience from us too.
