“Worshipers confront God as an overwhelming and yet appealing mystery, and then recognize themselves as creaturely.” Dictionary of Biblical Theology
A peasant may not know he is a peasant until he stands in the presence of a king. In the same way, a man may fancy himself a god until he stands in the presence of the Almighty. To experience the holy is first and foremost a confrontation between the visions we cherish of ourselves and the infinite actuality of God. To see that God is God is to see, among other things, that we are not. And when we have this realization we have to worship.
That is why Leviticus as a book about the holiness of God is by necessity also a book about worship. Creatures worship the Creator in part to remind ourselves that we are in fact creatures. And when we worship the very elements of our worship serve again to remind us of our creaturely state. Indeed, for Israel, “the material of the offerings are the Israelite’s ordinary foodstuffs” (DOBT). They offered wheat, barely, oil, sheep, bulls—the very ordinary elements of their lives. As creatures ourselves all we can offer up to God is the stuff of creation. Without this realization, we might start to believe that what we offer up to God somehow impresses him, or worse still somehow obligates him. Herein lies the fundamental difference between pagan worship and the worship of God’s people. Yahweh cannot be conjured or bartered with. Worship is not an incantation by which we summon God to do our bidding. If Yahweh heeds us at all it is because of the surpassing splendor of his grace, not the supposed splendor of our worship.
It is easy to miss this because we might wonder why God require these ordinary things. Why does he ask for bulls and grain? It is not because he is hungry. After all, we can bring God nothing that he does not already possess. God does not require worship in the sense that we are offering up to him something that he lacks. God requires worship only in the sense that we as his creation are obligated to him for life and breath and all we possess. In this way our worship is not primarily a reminder to him of our devotion, but a reminder to ourselves of our great need. Take Israel as an example. They weren’t offering food to God because he needed to be fed, but because they did. To willingly offer up what sustains us is to cry out for a different kind of sustenance. Truly, man does not live by bread alone. We only truly remember this when we worship God.
