Meaning of "glory of the LORD" today?
What does "the glory of the LORD will be revealed" mean for believers today?

The Promise in Isaiah 40:5

“And the glory of the LORD will be revealed, and all flesh will see it together. For the mouth of the LORD has spoken.”


Defining “the Glory of the LORD”

• The visible, weighty manifestation of God’s holiness, power, and beauty

• Often displayed as radiant light or overwhelming presence (Exodus 24:16-17; Ezekiel 1:28)

• Never hidden for its own sake—always revealed so people will know, worship, and obey Him


The Glory Already Revealed in Christ

• Incarnation: “The Word became flesh and dwelt among us. We have seen His glory…” (John 1:14)

• Perfect representation: “The Son is the radiance of God’s glory…” (Hebrews 1:3)

• Gospel light: “God…has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.” (2 Corinthians 4:6)

Result for believers now:

– We don’t wait for a first glimpse; we look back to a glory already displayed at Bethlehem, Calvary, and the empty tomb.

– Faith rests on a revealed, historical Savior, not an abstract idea.


The Glory Still to Come

• Universal unveiling: “When He comes to be glorified in His saints and marveled at among all who have believed.” (2 Thessalonians 1:10)

• Cosmic filling: “The earth will be filled with the knowledge of the glory of the LORD as the waters cover the sea.” (Habakkuk 2:14)

• Eternal dwelling: “The city has no need of sun or moon…for the glory of God gives it light.” (Revelation 21:23)

Implication: the promise of Isaiah 40:5 will reach complete fulfillment at Christ’s return and in the new heaven and earth.


Why This Matters for Us Today

• Assurance: God’s spoken word guarantees what we hope for; our future is as certain as His character.

• Perspective: Present trials are temporary shadows compared to the coming radiance (Romans 8:18).

• Identity: We are “vessels of mercy…prepared beforehand for glory.” (Romans 9:23)

• Mission: Because “all flesh will see,” the church proclaims Christ so more eyes are opened before that day (Matthew 24:14).

• Transformation: “We all, with unveiled faces, behold as in a mirror the glory of the Lord and are being transformed into the same image.” (2 Corinthians 3:18)


Responding to the Promise

• Fix your hope on Christ’s return; let future glory shape present choices (1 Peter 1:13).

• Pursue holiness; sin dulls our vision of His beauty (Hebrews 12:14).

• Worship with confidence; God delights to reveal Himself to His people (Psalm 27:4).

• Speak the gospel; invite others to share in the coming worldwide revelation (2 Corinthians 5:20).
