Old Testament
Isaiah is the towering prophet of the Holy One of Israel, and no Old Testament book foretells the Messiah more fully. It opens with a vision of God's overwhelming holiness — 'holy, holy, holy' — before which Isaiah is undone, then cleansed and sent. Against the gulf between God's purity and human sin, Isaiah holds out astonishing grace: 'though your sins are as scarlet, they shall be as white as snow.' He foretells the coming Messiah in unmatched detail — Immanuel born of a virgin, the divine child called Mighty God and Prince of Peace, the Branch from Jesse's line, the herald who prepares the way. At the book's heart stands the Suffering Servant of chapter 53, 'pierced for our transgressions,' on whom 'the LORD has laid the iniquity of us all' — the clearest prophecy of the atonement. Isaiah ends in free grace and new creation: 'come, buy without money,' a Spirit-anointed herald of good news (the text Jesus claims in Nazareth), and the promise of new heavens and a new earth where God's redeemed people rejoice forever.
