Every chapter in Scripture ultimately belongs inside the Bible’s larger story of creation, fall, redemption, and new creation. Isaiah 27 may not name the gospel in the same way a New Testament paragraph does, but it still prepares us to understand human need, divine holiness, covenant faithfulness, and the hope fulfilled in Jesus Christ.
