The prophetic parables of the vineyard afford their hearers an illuminating vantage point upon the intergenerational peoplehood and unified moral agency of a nation. They offer us a new way of perceiving our national selves beyond the stifling frame of secularism.
The prophet Isaiah was a city dweller, but his mind was on the countryside. Trees, vineyards, and fields populate his thinking and that of his successors in this long book, where vegetation serves both as metaphor (as in Isaiah 5:1-7), and as the life-sustaining growth on which humans literally depend (as in vv. 8-10). Agricultural imagery appears from one end of the book to the other (1:8; 66:17), spelling out both judgment and hope.
