Isaiah 40 opens the second great movement of the book, addressed past the prophet's own day to a people who would one day sit in Babylonian exile. Their temple would be rubble, their king blinded, their land occupied. Into that future grief Isaiah is told to comfort. The comfort is not that empires will spare them — empires never do. It is that empires die like field grass while one thing does not: the word their God has spoken. To a deported people, this is not poetry. It is the only ground left to stand on.

From the writers we read together

Francis A. Schaeffer

evangelical theologian and founder of L'Abri (1912-1984)

Schaeffer's whole apologetic rests on a small set of claims, and one of them is that the universe is not mute. A God who exists but does not speak would be useless to us; a word that comes from anywhere but God would not last the season. Isaiah 40:8 is the verse Schaeffer's title is reaching for. The grass-and-flower image admits everything the modern mind insists on — that human projects are brief, that civilizations decay, that nothing on the surface of the earth is permanent. And then it adds the one sentence that changes the calculus: but the word of our God will stand forever.

Schaeffer wrote into a Western moment that had grown comfortable with the idea that all words are equally provisional — ours, the Bible's, anyone's. His answer was not to argue the Bible up to the level of God; it was to insist that God had already spoken down to the level of us, in propositional truth a child could understand. If that is so, then the question Isaiah puts to the exile is the question he puts to you: when everything you have built has dried out and fallen off the stem, will you still be standing on something that was said?
