What does "all flesh will see" mean?
What does "all flesh will see" reveal about God's power and authority?

Seeing the Promise in Context

Isaiah 40 opens with words of comfort to Israel after exile. In verse 5 we read, “And the glory of the LORD will be revealed, and all flesh will see it together. For the mouth of the LORD has spoken.” (Isaiah 40:5)


Key Words, Big Truths

• All flesh – every living person, without exception

• Will see – a literal, visible experience, not merely a rumor or private vision

• Together – simultaneously, no privileged few

• The mouth of the LORD has spoken – the guarantee; once God speaks, reality must follow


What This Reveals about God’s Power

• Irresistible Revelation – Nothing can hide or diminish His glory; He ensures it is publicly displayed.

• Unlimited Reach – His power extends over every continent, language, and culture.

• Unstoppable Fulfillment – The prophecy has the same certainty as creation itself; His word created the universe (Genesis 1), and His word here secures a worldwide unveiling.


What This Reveals about God’s Authority

• Universal Sovereignty – Because “all flesh” must witness, no earthly ruler or spiritual force can claim independence from Him (Psalm 24:1).

• Final Jurisdiction – He alone decides how, when, and to whom His glory is shown (Job 42:2).

• Covenant Keeper – His authority is displayed in faithfulness; what He promises He performs (Numbers 23:19).


Echoes through Scripture

Luke 3:6 – “And all humanity will see God’s salvation.” John the Baptist applies Isaiah’s promise directly to Jesus’ ministry.

Isaiah 66:18 – “They will come and see My glory.”

Habakkuk 2:14 – “The earth will be filled with the knowledge of the glory of the LORD as the waters cover the sea.”

Revelation 1:7 – “Every eye will see Him.” The promise climaxes at Christ’s return.

Philippians 2:10-11 – Every knee bows and every tongue confesses; universal recognition flows from universal sight.


From Prophecy to Fulfillment in Christ

John the Baptist cleared the way; Christ’s life, death, and resurrection unveiled divine glory (John 1:14). At His return that glory will be unmistakably visible to every person alive and resurrected.


Why It Matters Today

• Confidence – God’s plans encompass the globe; our circumstances fall within His sovereign gaze.

• Urgency – Because everyone will ultimately see His glory, sharing the gospel now carries eternal weight.

• Hope – No darkness, persecution, or doubt can cancel what God has spoken; His glory will shine for all to see.
