“The zeal of the LORD Almighty will accomplish this” -Isaiah 9:7b
If you had to come up with an overall theme for the book of Isaiah, this phrase would be a pretty good choice. Isaiah, more than any other prophet in the Old Testament, takes a view of history that is radically God-centered. In chapter 7, when king Ahaz won’t ask the Lord for a sign, God gives him one anyway. In Isaiah, the foreign empires of Assyria and Babylon are merely God’s instruments of judgement against Israel. Even the prophet Isaiah himself moves to the background of the book pretty quickly. We rarely hear firsthand accounts from him, and by chapter 40, he does not show up by name at all. Instead, it is God who is speaking and acting, in judgement and blessing, to Israel and the nations.
I think this is a very rare perspective today. Instead, ours is a materialist view of history (and our lives). When things in our lives go well, we look for ways in which we can take responsibility for them. What are the things that we have done that have caused us to be so successful in this? Or, when things go poorly, we seek to hone in on the primary cause, whether it’s something that we did or (more likely) something that others did. Then we work as hard as we can to make sure that it never happens again.
To be clear, there is nothing wrong with trying to learn from our mistakes or successes. However, often behind this desire is an assumption: it’s all on me. Whether things succeed or fail, whether we solve this problem or not, it’s ultimately on us. This tends to produce tremendous anxiety-driven activity.
Isaiah and the Incarnation are a strong critique of this view. They invite us to peek into the heavenly throne room to see what real action, what lasting change, actually looks like. Salvation, for Israel and for the nations, does not come through any program, process, power, or plan of humans. We are far too lost, far too frail to accomplish that. It is only by the zeal of the Lord, and the incarnation of the Son of God himself that salvation will be accomplished.
In Advent, we are given the opportunity to move from a man-centered focus on what we have done and are doing to improve ourselves, our communities, and the world. Instead, we get to focus on (and rest in) what the zeal of the Lord did and is doing through the life, death, and resurrection of the Son of God.
