Isaiah — Here Am I, Send Me

Who was Isaiah?

Isaiah ben Amoz was an eighth-century prophet who ministered in Jerusalem for approximately sixty years — from the last years of King Uzziah's reign through the reigns of Jotham, Ahaz, and Hezekiah. He was, by all available evidence, a man of education and social standing, with direct access to kings and the ability to move in the corridors of political and religious power. His writing is among the most literary and theologically sophisticated in the entire Old Testament. He had a wife who was herself a prophetess and at least two sons, whose names carried prophetic significance: Shear-jashub ("a remnant shall return") and Maher-shalal-hash-baz ("swift to the spoil, quick to the prey").

But the defining moment of Isaiah's story is not his family or his social position. It is a single vision recorded in Isaiah 6 — the year King Uzziah died — in which Isaiah saw the Lord sitting on a throne, high and lifted up, surrounded by seraphim who cried out the triple holiness that would become one of Christianity's most fundamental theological statements: "Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory." The temple shook. Smoke filled the house. And Isaiah's response was not wonder — it was devastation.

"Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts." This is the starting point of Isaiah's calling: not confidence, not readiness, not even a simple willingness. It is the complete collapse of a man who has seen what God is and knows immediately and absolutely what he is by comparison. Holiness, encountered directly, does not produce gradual improvement. It produces undoing. And the undoing, for Isaiah, was the beginning.

A prophet called to speak to people who would not hear — and the surrender that made it possible

The sequence in Isaiah 6 is worth slowing down on. The vision came first — the seraphim, the throne, the triple holiness, the shaking doorposts, the smoke. Then came Isaiah's response: "Woe is me! for I am undone." Then came the purging: a seraph flew to him with a live coal from the altar and touched his mouth, declaring his iniquity taken away and his sin purged. Only then did the call come.

The order matters: vision, undoing, purging, readiness, call, answer. Isaiah did not volunteer before the purging. He could not have — the vision had undone him. It was the coal, the declaration of forgiveness, the restoration of his lips, that made the answer possible. "Here am I; send me" is not the confident declaration of a man who has assessed his own capabilities and concluded he is adequate. It is the surrender of a man who has just learned he is not adequate and has been made clean anyway — and who responds to that grace with the only appropriate reply: I will go.

What God then told Isaiah about the nature of his mission is one of the most sobering briefings in prophetic literature. He was to speak to a people who would hear but not understand, see but not perceive. Their hearts would be fat, their ears heavy, their eyes shut. And if Isaiah asked how long, God's answer was: until the cities are waste and the land is utterly desolate and the people are far removed and a great forsaking is in the midst of the land. Isaiah was called to prophesy faithfully to people who would not respond — and he was told this at the outset.

He served for sixty years. Through the moral collapse of Ahaz, who aligned Judah with Assyria and introduced foreign worship to the temple. Through the faithful reign of Hezekiah, when Isaiah stood beside the king as Assyria threatened Jerusalem and the city was delivered. Through the long decades of prophesying hope to people who did not want to hear about judgment, and judgment to people who preferred comfortable religion. He wrote the words that would be quoted more frequently in the New Testament than any other prophet. He saw Christ seven hundred years before the manger.

God gave Isaiah a vision that spanned history — and sustained him through sixty years of prophetic faithfulness

What makes Isaiah's sixty years of ministry possible — ministry to a people who were told from the outset they would not respond — is the vision at the beginning. The man who has seen the Lord sitting on a throne, high and lifted up, who has been undone and purged and restored, who has answered "Here am I; send me," is not ultimately dependent on the audience's reception for his ability to continue. He saw the King. That seeing sustains everything that follows.

The book of Isaiah divides naturally into two major sections: chapters 1–39, which are predominantly judgment oracles addressed to Israel, Judah, and the surrounding nations; and chapters 40–66, which are predominantly comfort and hope, addressed to a people already in or facing exile. The transition at chapter 40 — "Comfort ye, comfort ye my people, saith your God" — is one of the great turning points in prophetic literature, as abrupt and total as the reversal it announces. The God who has been speaking judgment has not changed. His holiness has not diminished. But his comfort is as absolute as his justice, and Isaiah carried both.

The New Testament writers quote Isaiah more than any other Old Testament book except the Psalms. Matthew, Luke, John, Paul, and the author of Hebrews all return to Isaiah's words to explain and interpret what Jesus did. The suffering servant of Isaiah 53. The voice crying in the wilderness of Isaiah 40. The servant anointed to preach good news of Isaiah 61. The child born to sit on David's throne of Isaiah 9. God was telling Isaiah the shape of the salvation he was planning centuries before it arrived — and Isaiah wrote it all down faithfully, for an audience he knew would not fully receive it, because the vision at the beginning was sufficient to sustain the sixty years of what came after.

The man who said "Here am I" before he knew where he was being sent — what Isaiah's calling says about surrender

Isaiah answered "Here am I; send me" before God specified where. He said yes to being sent before he knew the terms. He responded to the call before he heard the briefing that would tell him the audience would not respond. The sequence matters: the vision, the undoing, the purging, then the readiness — and only then the call. Isaiah did not manufacture his own readiness. The coal from the altar did it. What he did was respond to the readiness with availability.

Most people who feel called to significant service spend enormous energy trying to make themselves worthy first — trying to resolve their own "unclean lips" problem through effort, discipline, and self-improvement before saying yes. Isaiah's model inverts this. The undoing came first. The purging was done to him by God, not by him for God. And the answer — "Here am I; send me" — came after the purging, not as preparation for it.

The second thing Isaiah's story offers is the possibility of faithful, sustained service in the face of what appears to be failure of impact. God told Isaiah at the outset that the people would not respond. He served for sixty years anyway. He wrote words that generations yet unborn would need — words that described the Messiah seven centuries before his birth, words that a crucified rabbi would stand up and apply to himself in a synagogue in Nazareth. The impact of Isaiah's ministry was not visible to Isaiah while he was living it. The faithfulness that made the impact possible had to be sustained by the vision at the beginning, not by the visible results along the way.

For anyone called to prophetic ministry, teaching, writing, or any form of service that involves speaking truth into a context that does not seem to be receiving it — Isaiah's story is a specific, sustaining word. You may not see the impact. The fruit may come after you are gone. What you have is the coal from the altar, the purging of grace, and the call: "Whom shall I send?" And what Isaiah offers you in response is the simplest, most costly, most freeing answer in all of Scripture: Here am I. Send me.
