"Seaching Isaiah: Line Upon Line" is a verse-by-verse deconstruction of the Book of Isaiah in the Old Testament with running commentary for each verse. The commentary is a compilation of various resources, but ultimately it is the author's personal ponderings and impressions of what the ancient prophet may have been trying to teach us about the modern times in which we live.
