Isaiah 45 proclaims the LORD as the unique righteous God and Savior before whom every knee will bow and every tongue acknowledge His sovereignty.

The fulfillment passages listed here (Phil 3:20; Titus 2:13) illuminate the Christian application summarized as "He is Lord and Savior." The correspondence is meaningful within the New Testament portrait of Jesus, but where the New Testament does not explicitly quote this exact Isaiah verse as fulfilled, it is best described as a theological or messianic correspondence rather than claiming more precision than the biblical writers themselves state.
