Israel’s Sin and the God Who Blots Out Transgressions

Isaiah 43:22–28 is a distinct movement within Isaiah’s book of comfort and new-exodus hope. It centers on Israel’s Sin and the God Who Blots Out Transgressions. In Isaiah’s own horizon, the Creator-Redeemer promises return from exile, confronts idols, raises Cyrus for a historical task, and unfolds the mission of the Servant. This unit shows how the book sets human pride, false refuge, or covenant failure against the LORD’s holiness, judgment, saving action, and promised restoration. Later canonical uses are explained separately: explicit New Testament interpretation is labeled explicit, while echoes, trajectories, and foreshadowing are kept at their proper evidence level.
