God’s majesty will be recognized by everyone, fulfilling His promise to redeem and reign among those who trust in Him.
“Then the glory of the LORD will be revealed, And all flesh will see it together; For the mouth of the LORD has spoken.” (v.5)
Isaiah, who prophesied primarily in the kingdom of Judah around 740-681 BC, declares that the time is coming when God’s majesty—His “glory”—will become unmistakably visible to everyone. By speaking of this unveiling of divine splendor, the glory of the LORD will be revealed, the prophet points ahead to a future moment when the Lord’s presence and power will transcend all human boundaries. The phrase all flesh will see it together underscores that this is a universal event, reaching every corner of humanity. Throughout scripture, such prophecy often relates to the coming of Jesus, the Messiah, who took on flesh so that people might behold God’s glory in human form (John 1:14). His coming fulfilled the promise that had once seemed distant, ensuring that God’s glory is not hidden but accessible to all.
When Isaiah says, For the mouth of the LORD has spoken, he is emphasizing that this message carries the highest authority. In that society, a royal decree was binding, and here, the decree comes from the King of kings. Centuries later, when John the Baptist applies Isaiah’s words to his own mission of “preparing the way,” the New Testament writers confirm that these ancient prophecies find their culmination in Christ (Luke 3:4-6). John the Baptist’s role was to pave the way for this revealed glory, declaring that no obstacle would prevent those who truly seek the Lord from experiencing His presence. It was a message of comfort and redemption for people who awaited God’s intervention, and the prophecy’s scope—involving “all flesh”—remains a reminder that no one is left out of God’s saving plan.
Such pardon and revelation of God’s glory also ties to the greater theme of transformation: mountains lowered, valleys raised, and barriers removed (Isaiah 40:4), indicating that hearts once hardened would become receptive to the wonder of the Lord. In Jesus’s ministry, many witnessed healings, miracles, and teachings that showcased God’s power and grace in the flesh. Isaiah’s announcement in this verse stands as a bold assurance that nothing can thwart the Lord’s intention to reveal His character and salvation to humanity.
