Who Was Isaiah? The Prophet Who Saw Jesus 700 Years Early

Who Was Isaiah?

Isaiah is often called the greatest of the Old Testament prophets — and with good reason. He ministered in Jerusalem during one of the most turbulent periods in Israel's history, watching the northern kingdom fall to Assyria while warning the southern kingdom that judgment was coming unless they turned back to God. But what makes Isaiah truly extraordinary is what he saw: vivid, detailed prophecies about a coming Messiah that read, centuries later, like eyewitness accounts of Jesus of Nazareth.

A Vision That Launched a Ministry

Isaiah's call to ministry was unlike any other in Scripture. In the year King Uzziah died, Isaiah had a vision of God seated on a high and exalted throne, with seraphim — six-winged angelic beings — crying out to one another above Him. The sound of their voices shook the doorposts of the Temple. Isaiah's immediate reaction was not awe but terror:

"Woe to me! I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the Lord Almighty." — Isaiah 6:5

A seraph flew to him with a burning coal and touched his mouth, declaring his guilt taken away. Then came the call: "Whom shall I send? And who will go for us?" Isaiah's response — "Here am I. Send me!" — became one of the defining statements of prophetic calling in the Bible.

Warnings to a Nation That Wouldn't Listen

Isaiah's ministry spanned four kings of Judah and lasted at least forty years. His message was consistent: the nation was pursuing idols, exploiting the poor, making political alliances instead of trusting God, and heading toward disaster. The Assyrian empire was rising, and Isaiah warned the kings of Judah not to seek protection from Egypt or other nations — but from God alone.

His prophecies were not always welcomed. Tradition holds that Isaiah was eventually executed by being sawn in two during the reign of the wicked king Manasseh — a fate referenced in the New Testament's hall of faith in Hebrews 11.

The Prophecies That Point to Jesus

What makes Isaiah's book so staggering is its forward-looking content. Written around 700 BC, it contains prophecies that the New Testament writers repeatedly cite as fulfilled in Jesus. A virgin will give birth to a son called Immanuel. A child will be born who will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. A suffering servant will be wounded for our transgressions, crushed for our iniquities — and by his wounds we will be healed.

"He was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed." — Isaiah 53:5

Isaiah 53, written 700 years before the crucifixion, describes a man who was despised and rejected, who suffered silently, who was led like a lamb to the slaughter. When Philip the evangelist in Acts 8 met an Ethiopian official reading this chapter and asked if he understood it, the official asked who the prophet was writing about. Philip began with that passage and told him the good news about Jesus.

Why Isaiah Still Matters

Isaiah's book is the most-quoted Old Testament book in the New Testament — cited over 400 times. He saw the big picture of redemption history with a clarity that is breathtaking. His words of comfort — "Fear not, for I have redeemed you; I have called you by name, you are mine" — have carried generations of believers through the darkest of nights.
