The author of Hebrews is employing Old Covenant prophetic categories identifying patterns of messianic identity and thereby proclaiming the glory of Christ. This book continues to unfold expounding the absolute monergism intrinsic to the incarnation and its effects for all in Christ. The work of Christ alone is celebrated in its manifold fulfillment and comprehensive finality. Christ is declared in His person and His work. Both office and execution are in view in these opening chapters. Isaiah 41-43 provide additional context for trans-covenantal understanding of the implications of Christ's person and obedience. In these verses preceding the messiah by centuries, the 'coastlands' are called as the audience to behold the Holy One of Israel (who doubles as Redeemer) as He sovereignly intervenes on behalf of the offspring of Abraham (Is 41:8). These ancient words foretell a day when all nations, ends of the earth, remote corners and peoples abroad will behold an event of cosmic proportions that will signal the hope of history. Here is salvation belonging to God, granted to His people.
