Holy, Holy, Holy — and a Burning Coal

In the year that King Uzziah died. Isaiah dates his vision by a funeral, and the date is doing real work. Uzziah had reigned for fifty-two years — for nearly everyone alive, the only king they had ever known — and his death meant the ground was moving. Assyria was rising in the east; the future had gone dark. And it is in that year, with the earthly throne standing empty, that Isaiah walks into the temple and sees the throne that has never been empty for a moment: “I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple.” Kings die. The King does not.

Above the throne hover the seraphim — the word means “burning ones,” creatures of living fire. And yet even these blazing, sinless beings cannot bear to look on the One they attend: of their six wings, only two are for flying — with two they cover their faces before his holiness, and with two they cover their feet. If creatures of fire must veil their eyes in that presence, we begin to feel the weight of where Isaiah is standing. And their song is the only attribute of God that Scripture ever raises to the third power. Hebrew has no exclamation points; it intensifies by repeating — and here, alone in the Bible, the repetition goes to three. Not love, love, love — though God is love. Not mercy, mercy, mercy — though his mercy endures forever. Holy, holy, holy: the blazing, unapproachable, uncreated otherness of God, of whom the whole earth is full of glory whether we notice or not.

Watch what this vision does to the best man in Judah. Isaiah does not say “how inspiring.” He says, “Woe is me! For I am lost” — the word means undone, unraveled, coming apart at the seams. In the chapter just before this one, Isaiah had pronounced six woes on the sinners around him: woe to the land-grabbers, woe to the drunkards, woe to those who call evil good (Isaiah 5:8–23). The seventh woe he pronounces on himself. And of all the things he could confess, it is his lips — the prophet's one instrument, the best thing he has. In the light of that throne, our finest member turns out to be unclean, just as Joshua the high priest stood in that other throne room in filthy garments. Isaiah would later confess it for all of us: “all our righteous deeds are like a polluted garment” (Isaiah 64:6). We do not meet the holiness of God and come away improved; we come away undone.

And then — notice that Isaiah does nothing, offers nothing, fixes nothing — a seraph flies to him with a burning coal taken from the altar. The altar: the one place in the temple where sacrifice burned, where blood had been shed. Atonement comes to the sinner; the sinner does not climb to it. The coal touches the very place of his confessed uncleanness, and the words spoken over him are pure gift: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.” A man touched by fire from God's altar — and not destroyed. Grace gets the first word; it always has. Isaiah is not cleansed because he volunteered; he is about to volunteer because he has been cleansed.

But whom did Isaiah see on the throne? John answers with the boldness of an eyewitness: “Isaiah said these things because he saw his glory and spoke of him” (John 12:41) — of Jesus. The thrice-holy King, high and lifted up, before whom the burning ones hide their faces, is the same Lord who said in the temple courts, “before Abraham was, I am”. And now trace Isaiah's own phrase through his book, because it will take us somewhere we do not expect. “High and lifted up” appears again at Isaiah 52:13 — “Behold, my servant… shall be high and lifted up, and shall be exalted” — and the very next verse says his appearance was marred beyond human semblance, for he was “pierced for our transgressions” (Isaiah 53:5). Isaiah reserves the words of the throne for a crucified servant. John completes the thought in the same chapter where he tells us Isaiah saw Christ's glory: “And I, when I am lifted up from the earth, will draw all people to myself” — and John adds, “he said this to show by what kind of death he was going to die” (John 12:32–33). As the bronze serpent was lifted up in the wilderness, so the Son of Man was lifted up (John 3:14). The throne and the cross are the same elevation. Calvary is where the glory Isaiah saw burns brightest.

And there the coal and the altar meet their fulfillment. At the cross, the altar, the sacrifice, and the priest are one Person. The thrice-holy One was treated as the unclean one — made “to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Corinthians 5:21) — so that people of unclean lips could hear, full and final, “your guilt is taken away, and your sin atoned for.” What flew to Isaiah as an ember flies to us as a finished fact: the mercy seat in person, the sacrifice already burned, the live coal of a completed atonement touched to everything in us we know is unclean.

Only then does Isaiah hear the voice: “Whom shall I send, and who will go for us?” And the man who was coming apart three verses earlier answers with one Hebrew word — hineni — “Here am I! Send me.” The order is the whole gospel: cleansing precedes calling. We do not serve our way to the coal; the coal makes servants. And behind Isaiah's answer stands a greater one, for when heaven asked who would go, the Son himself said, “Behold, I have come to do your will, O God” (Hebrews 10:7) — the true and better hineni, spoken before the foundation of the world and kept all the way to the cross. The seraphim are singing still; one day we will stand with them, where the song has never stopped: “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come” (Revelation 4:8). Until then, let us take our place in the story exactly where Isaiah found his — undone, touched, forgiven, and sent — our unclean lips made clean by Another, and given something eternal to sing.
