Maybe I’m the product of overexposure, but at this point I’m willing to argue it out with anyone: Isaiah is the greatest piece of literature that has ever been written.
More pointedly, Isaiah has what British evangelicalism needs: a thoroughly classical doctrine of God, which undergirds a vision of salvation that’s as sweeping as creation and would stop us putting our faith in powerful men.
Unique By His Very Nature
Isaiah’s doctrine of God is breathtaking, presenting us with a God who is genuinely incomparable. Here’s an example: “To whom then will you compare me, that I should be like him? says the Holy One. Lift up your eyes on high and see: who created these?” ─Isaiah 40v25.
This isn’t just an attack on the number of gods in paganism, it’s an attack on the nature of the gods in paganism. The gods of paganism are many, but that isn’t the deepest problem that Isaiah identifies. The deepest problem with the gods of paganism is that it’s possible to compare them with one another: they are relative. Pagan gods are comparable and relative because these ‘gods’ can exist in varieties: you could tweak and change any of them─add some grace and power, remove some wisdom─and they’d become different gods, but they’d still be ‘gods’. No pagan god exists in a category uniquely its own, truly and totally independent from everything else, absolute and unchangeable by definition.
Here’s where the rubber hits the road: if no pagan god is truly and totally independent, that means that no pagan god could ever be truly and totally dependable. If you throw the weight of your life at one of these gods, you’ll quickly find that they are themselves leaning on something else: whoever or whatever has been determining how much grace and power and wisdom they have.
Not so the God of Isaiah.
Isaiah’s God is unique by his very nature.
There are two categories: God, and everything that God created. He isn’t relative, a variation on a theme. As Steven J. Duby puts it in God In Himself, “There is no impersonal form of life, wisdom, or love “out there” from which God must draw in order to be what he is.” If it was even possible for this God to change, He would cease to be God. He isn’t ‘the most’, He is ‘the only’. Isaiah’s doctrine of God isn’t that “the most powerful” also─fortunately─happens to be “the most gracious”. It’s that God is incomparable and unchanging, truly and totally independent and therefore truly and totally dependable.
