Prophecy

The Message of Isaiah 6: Holy God, Willing Servant


Chapter Summary

Isaiah 6 marks a pivotal moment, shifting from general prophecies to the personal calling of the prophet Isaiah. In a stunning vision, Isaiah comes face-to-face with the majestic holiness of God, which reveals his own sinfulness and leads to his cleansing and commission. This chapter lays the groundwork for his entire ministry, showing how an encounter with God transforms an ordinary person into a willing messenger.

Core Passages from Isaiah 6

  • Isaiah 6:3And one called to another and said: “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!”

    The seraphim's repeated cry of 'Holy, holy, holy' establishes the central theme of the chapter: God's perfect, overwhelming, and utterly separate nature.
  • Isaiah 6:5And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!”

    This is Isaiah's raw and honest reaction to God's holiness, recognizing that his own sin, and that of his people, makes him unworthy to be in God's presence.
  • Isaiah 6:8And I heard the voice of the Lord saying, "Whom shall I send, and who will go for us?" Then I said, "Here I am! Send me."

    After being cleansed and forgiven, Isaiah's fear turns to courage, and he volunteers for God's mission without hesitation, providing a powerful example of a transformed heart.
An ordinary life is forever changed by an overwhelming encounter with the divine, leading to purification and purpose.

Historical & Cultural Context

A Throne Room Vision in a Time of Crisis

The chapter opens at a moment of national instability. King Uzziah, who had reigned for over 50 years, has died, leaving a power vacuum and an uncertain future for the nation of Judah. In this climate of earthly anxiety, Isaiah is given a vision that redirects his focus from a vacant human throne to the eternally occupied throne of heaven. This vision establishes that despite the turmoil on earth, God remains sovereign and in complete control.

A Willing Volunteer for a Difficult Mission

After being overwhelmed by God's holiness and then miraculously cleansed, Isaiah hears God ask who will carry His message. Isaiah volunteers immediately, only to be assigned a heartbreaking task. He is to preach a message that, because of the people's stubbornness, will actually harden their hearts and lead to judgment. This difficult commission underscores that obedience to God sometimes means delivering an unpopular truth, trusting Him with the results.

The humbling encounter with divine presence ignites a profound purification and acceptance of sacred purpose.

Isaiah's Vision, Cleansing, and Commission

Set in the year of King Uzziah's death, Isaiah 6 transports us from a place of earthly uncertainty into the very throne room of God. In this dramatic scene, Isaiah witnesses the breathtaking majesty of the Lord, which leads to a personal crisis of faith, a powerful moment of forgiveness, and a life-altering call to serve as God's prophet to a resistant nation.

The Vision of God's Overwhelming Holiness  (Isaiah 6:1-4)

1 In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple.
2 Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew.
3 And one called to another and said: “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!”
4 And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke.

Commentary:

Isaiah has a stunning vision of God on His throne, surrounded by angelic beings worshiping His absolute holiness.

Isaiah sees the Lord on a throne, so magnificent that the train of His robe fills the entire temple. He is attended by seraphim, fiery angelic beings who cover themselves in humility and cry out, “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!” The sound of their voices shakes the temple to its foundations, and the room fills with smoke, symbolizing the powerful and mysterious presence of God. This is a full-sensory experience of God's awesome power and absolute purity. It is not a gentle, quiet scene. It's designed to show that God is unlike anyone or anything else, existing in a category all His own.

Isaiah's Cry of Unworthiness and God's Act of Grace  (Isaiah 6:5-7)

5 And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!”
6 Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar.
7 And he touched my mouth and said: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”

Commentary:

Overwhelmed by his sin in God's presence, Isaiah is miraculously cleansed and forgiven by a burning coal from the altar.

Faced with perfect holiness, Isaiah is immediately crushed by the weight of his own sinfulness. He cries out, “Woe is me! For I am lost,” recognizing that he, a man of “unclean lips,” has no right to stand before the pure King of heaven. His despair stems from his own failings and from living among an equally sinful people. As he pronounces his own doom, one of the seraphim acts. The angel takes a burning coal from the altar - the place of sacrifice and atonement - and touches it to Isaiah's lips. This act symbolizes a painful but complete purification, as the angel declares, “your guilt is taken away, and your sin atoned for.” God doesn't leave Isaiah in his despair. He provides the cleansing he so desperately needs.

The Call and the Response  (Isaiah 6:8)

8 And I heard the voice of the Lord saying, "Whom shall I send, and who will go for us?" Then I said, "Here I am! Send me."

Commentary:

After being forgiven, Isaiah hears God's call for a messenger and immediately volunteers for service.

With his guilt removed, Isaiah is now able to hear the voice of the Lord. God's question, “Whom shall I send, and who will go for us?” is a divine invitation. It's a moment of decision. Having experienced both the terror of judgment and the relief of grace, Isaiah's response is immediate and unreserved: “Here I am! Send me.” He doesn't ask where he's going or what the job entails. His heart, transformed by grace, is now fully available to God. This verse is the turning point of the chapter, moving from vision and personal renewal to active mission.

A Heartbreaking Mission and a Glimmer of Hope  (Isaiah 6:9-13)

9 And he said, "Go, and say to this people: "'Keep on hearing, but do not understand; keep on seeing, but do not perceive.'
10 Make the heart of this people dull, and their ears heavy, and blind their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn and be healed.
11 Then I said, “How long, O Lord?” And he said: “Until cities lie waste without inhabitant, and houses without people, and the land is a desolate waste,
12 And the Lord removes people far away, and the forsaken places are many in the midst of the land.
13 And though a tenth remain in it, it will be burned again, like a terebinth or an oak, whose stump remains when it is felled." The holy seed is its stump.

Commentary:

Isaiah is given the difficult task of preaching a message of judgment that will harden hearts, but God promises a small remnant will survive.

Isaiah's first assignment is a difficult one. God tells him to deliver a message that will cause the people to hear without understanding and see without perceiving. In essence, their hearts will become even more hardened against God. This is a prophecy of judgment. Because the people have refused to listen, their spiritual senses will be dulled, leading them toward exile and destruction. Isaiah asks how long this will last, and God's answer is bleak: until the land is desolate. Yet, even in this severe judgment, there is a final word of hope. Like a tree that is cut down, a stump - a “holy seed” - will remain. This remnant is the promise that God will not completely abandon His people. A future restoration is still possible.

God's Majesty, Human Frailty, and Divine Hope

The Holiness of God

This chapter puts God's holiness on full display. It is about His 'otherness' - His supreme, majestic, and transcendent nature that inspires both awe and fear. It is not about moral perfection. The entire throne room scene is designed to show that God is infinitely greater than we can imagine.

The Reality of Human Sin

When Isaiah, a righteous man and a prophet, sees God's holiness, his immediate reaction is a deep awareness of his own sin. This teaches us that in the light of God's perfection, our own flaws become impossible to ignore. A true understanding of God leads to an honest understanding of ourselves.

Grace and Atonement

Isaiah's cry of “Woe is me!” is met not with punishment, but with purification. The burning coal from the altar signifies that God Himself provides the way for sin to be forgiven - a concept known as atonement. This act of grace is what makes a relationship with a holy God possible for sinful people.

The Hope of the Remnant

Even within a message of severe judgment, God includes a promise of hope. The image of the 'holy seed' in the stump of a felled tree shows that God's plan of redemption will not be thwarted. He always preserves a faithful few through whom He will fulfill His ultimate purposes.

Encountering the sacred transforms the human spirit, inspiring awe and a profound sense of unworthiness in the face of divine glory.

Responding to God's Holiness Today

How does Isaiah's vision of God's holiness challenge my own view of God?

Isaiah's vision in verses 1-4 reminds you that God is a majestic and holy King who deserves reverence, not merely a friend or a helper. It challenges you to move beyond a casual view of God and to cultivate a sense of awe for His power and purity in your worship and daily life.

When I feel my own 'unclean lips' or unworthiness, how does Isaiah's experience offer hope?

Isaiah's despair in verse 5 is met by God's immediate grace in verse 7. This shows that God doesn't expect you to be perfect before you come to Him. He meets you in your brokenness, offers forgiveness, and provides the cleansing you need to be in a right relationship with Him.

What does Isaiah's response, 'Here I am! Send me,' teach me about availability to God?

Isaiah's response in verse 8 was immediate and unconditional, offered before he knew the difficult details of his mission. It challenges you to cultivate a heart that is open and available to God's leading, trusting that the One who calls you is also the One who will equip and sustain you.

Encountering Holiness, Answering the Call

Isaiah 6 shows that a true encounter with the living God is a life-altering event. It begins by revealing His awesome holiness, which in turn exposes our own deep need for grace. But God does not leave us in our brokenness. He reaches out to cleanse and restore us, not only for our own sake, but to prepare us for His mission. The ultimate message is that experiencing God's forgiveness naturally leads to a heart that says, 'Here I am! Send me.'

What This Means for Us Today

The pattern in Isaiah 6 is timeless: seeing God clearly leads to seeing ourselves honestly, which opens the door to receiving His grace and hearing His call. God is still asking, 'Whom shall I send?' and He invites us, once cleansed by His grace, to be His voice of truth and hope in our world.

  • In what areas of my life have I lost a sense of awe for God's holiness?
  • How can I be more open to God's cleansing, admitting my need for His grace daily?
  • If God asked, 'Who will go for us?' today, what would my honest answer be, and what might be holding me back?

Discussion Questions

  • The vision happened 'in the year that King Uzziah died.' How does a moment of earthly instability or loss sometimes open our eyes to God's heavenly stability and sovereignty?
  • Isaiah felt completely undone by his sin in God's presence. Why is it important to have moments where we feel our need for grace, rather than always focusing on our strengths?
  • God commissioned Isaiah to deliver a message that would harden people's hearts. How can we trust God's purpose even when His methods seem difficult or counterintuitive to us?
