Isaiah 40:5 – “And the glory of the Lord will be revealed, and all people will see it together. For the mouth of the Lord has spoken.”
Extended Explanation
Isaiah 40:5 proclaims a remarkable promise: God’s glory will be revealed, and it will be visible to everyone. The verse emphasizes the certainty of this event, as it is rooted in the unchanging word of God. The “glory of the Lord” refers to His majesty, holiness, and presence being made manifest in a way that leaves no doubt about His power and sovereignty.
The phrase “all people will see it together” suggests a universal scope—God’s glory will not be hidden or confined to one nation or group but will be made evident to the entire world. This points to a future event where God’s greatness is displayed unmistakably, fulfilling His promise of salvation and restoration.
Historical Context
At the time Isaiah was written, the people of Judah faced the consequences of their rebellion against God, including exile in Babylon. Isaiah 40 begins a section of the book that offers hope and comfort, promising that God would redeem and restore His people. This verse reassures the exiles that their suffering is not the end of the story—God’s glory will ultimately prevail.
This prophecy also points beyond the immediate historical context to the coming of the Messiah and the establishment of God’s kingdom. It speaks of a time when God’s work of salvation will be complete and His glory fully revealed.
Theological Implications
Isaiah 40:5 emphasizes the certainty and universality of God’s plan. The assurance that “the mouth of the Lord has spoken” highlights the trustworthiness of God’s promises. His word is unchanging and powerful, guaranteeing that His purposes will come to pass.
The verse also underscores God’s desire to reveal Himself to all people. His glory is not limited to Israel but extends to the entire world, reflecting His redemptive plan for humanity.
Literary Analysis
This verse builds on the preceding verses, which describe the preparation for the Lord’s coming. The unveiling of God’s glory is the culmination of that preparation. The parallel structure—“the glory of the Lord will be revealed, and all people will see it together”—creates a sense of balance and completeness, emphasizing the widespread impact of God’s revelation.
The declaration, “For the mouth of the Lord has spoken,” adds weight and authority to the promise. It assures readers that this is not wishful thinking but a divine decree that cannot fail.
