Inspired by Isaiah 6:3–13, this conversation with conservative biblical theology, exploring God’s holiness, the Trinity, Christ as the cleansing coal, and the sobering nature of Isaiah’s call.
Scene: The Back Booth of a Late-Night Diner
The neon sign outside flickers against the window, and the hum of passing cars fills the quiet diner. Two friends, Sam and Daniel, sit across from one another in a worn red booth. Their Bibles are open, coffee half-gone, and the weight of Isaiah 6 sits between them heavier than the plates on the table.
Sam: Every time I read Isaiah 6, it hits harder. Those seraphim crying “Holy, holy, holy”—that’s not a choir. That’s an earthquake.
Daniel: Exactly. People think angels are soft. These are burning creatures shaking the building by proclaiming God’s holiness. And if that’s what His holiness does to angels, imagine what it does to us.
Sam: It flattened Isaiah. He wasn’t signing up for ministry; he was confessing his sin. “Woe is me.” That’s the only thing a man can say when God peels back the veil.
Daniel: And the coal… people miss that part. That coal is Christ. It’s from the altar—the place of sacrifice. God didn’t say, “Try harder.” He said, “Your sin is atoned for.” Isaiah couldn’t fix himself. God had to do it.
Sam: And it wasn’t gentle. It burned. Holiness always burns before it heals. That alone could be a whole sermon.
Daniel: And then God speaks. “Whom shall I send, and who will go for Us?” That “Us” jumps right off the page. It’s the Trinity. Father, Son, and Spirit in full agreement.
Sam: And Isaiah finally stands up after cleansing. He says, “Here am I, send me.” But he had no idea what he was volunteering for.
Daniel: Yeah… because God basically tells him, “Go preach to a people who won’t listen.” That’s a nightmare assignment. Imagine being told your ministry will harden people instead of heal them.
Sam: That’s judgment. Not arbitrary—judicial. They refused God for so long that eventually the lights go out. Hearing without understanding, seeing without perceiving. That’s terrifying.
Daniel: It’s happening now too. When people sit under the Word for years and mock it, twist it, reject it—eventually God lets them have what they want. Blindness becomes their judgment.
Sam: Isaiah asks, “How long?” And God says, “Until the cities are ruined.” That’s the part nobody wants to talk about. God’s patience isn’t weakness. Judgment comes when sin demands it.
Daniel: But thank God it doesn’t end there. The stump. The holy seed. That’s Christ. Even in judgment, God preserves a remnant. Even when the tree is cut down, the root of promise is still alive.
Sam: So the whole chapter moves from holiness to cleansing to calling to judgment to hope. It’s the Gospel before the Gospel.
Daniel: Exactly. And it reminds us that God doesn’t compromise. He doesn’t rewrite holiness. He doesn’t blink at sin. But He always keeps a remnant, and He always brings Christ right through the ashes.
Sam: Makes you realize how serious God still is today. Holiness hasn’t changed. Judgment hasn’t changed. Grace hasn’t changed. And the Trinity is still saying, “Who will go for Us?”
Daniel: And the answer is still the same. But only from people who have been burned clean first.
The God Isaiah saw is the God who still reigns—holy, sovereign, unchanging, and still calling cleansed servants to walk into a world that desperately needs the truth.

Holman Christian Standard Bible
Isaiah 6:3-13
6 Then one of the seraphim flew to me, and in his hand was a glowing coal that he had taken from the altar with tongs. 7 He touched my mouth with it and said:
Now that this has touched your lips,
your wickedness is removed
and your sin is atoned for.
8 Then I heard the voice of the Lord saying:
Who should I send?
Who will go for Us?
I said:
Here I am. Send me.
9 And He replied:
Go! Say to these people:
Keep listening, but do not understand;
keep looking, but do not perceive.
10 Dull the minds of these people;
deafen their ears and blind their eyes;
otherwise they might see with their eyes
and hear with their ears,
understand with their minds,
turn back, and be healed.
11 Then I said, “Until when, Lord?” And He replied:
Until cities lie in ruins without inhabitants,
houses are without people,
the land is ruined and desolate,
12 and the Lord drives the people far away,
leaving great emptiness in the land.
13 Though a tenth will remain in the land,
it will be burned again.
Like the terebinth or the oak
that leaves a stump when felled,
the holy seed is the stump.
