700 years before Jesus was born, a man in Jerusalem wrote down the details of His death.

He wrote Jesus would be beaten until He no longer looked human. That He’d stay silent at His own trial. That He’d be killed alongside criminals, yet be buried in a rich man’s grave. And then, strangest of all, that after dying He’d see His children and live a long life.

Sceptics have a quick answer to this: Christians made it all up afterwards and slipped it into the Bible.

There’s one problem with that answer. In 1947, a shepherd boy found a jar in a cave near the Dead Sea. Inside was a complete copy of Isaiah, written out roughly a 100 years before Jesus was born. Every line was already there. So the words are old.

Why Isaiah Is Called the Fifth Gospel

The Bible has 4 Gospels: Matthew, Mark, Luke and John. The word “gospel” simply means “good news”—the announcement of who Jesus is and what He has done.

Isaiah isn’t a fifth one. It was written centuries earlier, by a prophet. But the nickname stuck for 3 reasons.

• The early church noticed it. Jerome, who translated the Bible into Latin in the fourth century, said Isaiah should be called an evangelist rather than a prophet, because he describes Christ so fully that he seems to be writing history rather than prophecy.
• The apostles leaned on it. Isaiah is quoted in the New Testament around 60 times—more than any other book except Psalms—and echoed hundreds of times more.
• The first recorded conversion outside Israel began there. In Acts 8, an official from Ethiopia is reading Isaiah 53 in his chariot. Philip climbs in, and “beginning with this Scripture he told him the good news about Jesus” (Acts 8:35).

The Key That Unlocks the Whole Book

First, let’s settle a question of method: are we allowed to look for Jesus in Isaiah?

Jesus answered that Himself. On the Sunday He rose from the dead, He walked with two confused disciples and gave them a Bible study. Luke records it: “And beginning with Moses and all the Prophets, He interpreted to them in all the Scriptures the things concerning Himself” (Luke 24:27).

This was no one-off. Earlier He had told His critics the Scriptures bear witness about Him (John 5:39), and that if they really believed Moses, they’d believe Him, for Moses wrote of Him (John 5:46).

The Clue Hidden in Isaiah’s Own Name

Start with the author’s name. In Hebrew it is Yesha‘yahu, and it means “the LORD saves”. The name Jesus, in Hebrew Yeshua, comes from the same root and means the same thing.

That’s no coincidence dressed up as evidence. It’s the thesis of the book. Isaiah writes: “Behold, God is my salvation; I will trust, and will not be afraid; for the LORD GOD is my strength and my song, and He has become my salvation” (Isaiah 12:2).

God declares: “I, I am the LORD, and besides me there is no saviour” (Isaiah 43:11). God insists He will do the rescuing Himself, personally, and that He will share that honour with no one.

Yet the same book promises a child, a king, a servant and a conqueror who will do the rescuing. So who is He?

Isaiah spends 66 chapters closing that gap. The New Testament says the gap closes on one person.

Part One: The King God Promises (Isaiah 1–39)

Isaiah preached during a terrifying stretch of history. Understanding the pressure he lived under makes his promises land harder.

Isaiah’s world: a short timeline

• About 740 BC—Isaiah sees God on His throne and is sent to a nation that will not listen (Isaiah 6).
• 722 BC—the northern kingdom of Israel is destroyed by Assyria, the superpower of the day.
• 701 BC—the Assyrian army surrounds Jerusalem. The city survives only because God intervenes.
• 586 BC—Babylon burns Jerusalem, more than a century after Isaiah spoke. He had already warned of it, and already promised what lay beyond it.

Into that fear, Isaiah keeps promising a coming King. Here are the clearest examples, and what the New Testament writers do with them.

The strange chapters in the middle

Chapters 36–39 break the pattern. Suddenly we’re reading history: King Hezekiah, a siege, a prayer, a rescue, and then a bad decision that guarantees Babylon will one day carry his sons away.

Why put that here? Because Hezekiah is the best king left, and he’s still not enough. He’s godly, even prayerful. God answers—and Hezekiah still fails, and still dies. The throne is still empty.

Part Two: The Servant God Sends (Isaiah 40–55)

Chapter 40 changes the tone completely. The shouting stops and the comfort begins.

It opens with a herald: “In the wilderness prepare the way of the LORD; make straight in the desert a highway for our God” (Isaiah 40:3). Hold on to that verse—we’ll come back to it, because it carries more weight than any other single line in this post.

Then comes the figure who dominates these chapters: the Servant. Four passages, usually called the Servant Songs, describe someone God chooses, fills with His Spirit, and sends to bring justice to the nations—and who is rejected, beaten and killed doing it.

• Isaiah 42:1–9—the chosen Servant who will not break a bruised reed.
• Isaiah 49:1–13—the Servant sent not only to Israel but as a light for the nations.
• Isaiah 50:4–9—the Servant who gives His back to those who strike Him.
• Isaiah 52:13–53:12—the Servant who is “pierced for our transgressions” and “crushed for our iniquities” (Isaiah 53:5), bearing the punishment others deserved.

We’ve treated these two subjects in detail elsewhere, so here we’ll simply note the conclusion: the Servant suffers in the place of guilty people, which is what the Bible calls substitution—one person taking the penalty owed by another. Then Isaiah says something impossible for a dead man: “he shall see his offspring; he shall prolong his days” (Isaiah 53:10).

The detail almost everyone misses

Watch the grammar. Through Chapters 42 to 53, the Servant is always singular—one person. Then, from Isaiah 54:17 onwards, the word turns plural: “the heritage of the servants of the LORD”. It stays plural for the rest of the book (Isaiah 65:8–9; Isaiah 66:14).

One Servant dies. Many servants appear. Isaiah’s own text moves from Christ to the people who belong to Him, and the link between the two is His death. Those servants are the “offspring” of Isaiah 53:10—the family a dying man couldn’t otherwise have.

Part Three: The Conqueror God Is (Isaiah 56–66)

The last section adds something the earlier chapters only hinted at. The Servant doesn’t stay a victim.

In Isaiah 59, God looks for someone who can put things right and finds no one, so He acts Himself: He puts on righteousness like body armour and a helmet of salvation, and a Redeemer comes to Zion (59:16–20). Paul quotes that promise in Romans 11:26, and borrows the armour picture in Ephesians 6.

In Isaiah 63, a figure comes from Bozrah in clothing stained red, treading the winepress of God’s judgement alone. John sees the same figure in Revelation 19:13—Christ returning, His robe dipped in blood.

And the book ends where the Bible ends: “For behold, I create new heavens and a new earth” (Isaiah 65:17), quoted in 2 Peter 3:13 and pictured in Revelation 21.

The most famous comma in the Bible

Between those two pictures sits Isaiah 61. The speaker says: “The Spirit of the Lord GOD is upon me, because the LORD has anointed me to bring good news to the poor” (Isaiah 61:1). He is sent to bind up broken hearts, free prisoners, and proclaim “the year of the LORD’s favour, and the day of vengeance of our God” (61:2).

In Luke 4, Jesus stands up in His home town, reads this passage aloud—and stops. He stops in the middle of verse 2, after “the year of the LORD’s favour”, before “the day of vengeance”. He rolls up the scroll, sits down, and says: “Today this Scripture has been fulfilled in your hearing” (Luke 4:21).

The Strongest Evidence: Isaiah’s God Is Jesus

So far we’ve looked at predictions. This next argument is different, and it’s the one that makes the case watertight.

New Testament writers repeatedly take passages where Isaiah is talking about the LORD—God Himself, using His personal covenant name—and apply them to Jesus without blinking.

Notice who is doing this. Peter, Paul and John were Jewish men taught to say daily the LORD our God is one. They’d have died rather than give God’s honour to a created being—and many of them did die rather than deny what they were saying about Jesus.

BB Warfield pointed out the titles in Isaiah 9:6 aren’t flattery for a good king; “Mighty God” is used of the LORD Himself two chapters later (Isaiah 10:21). Richard Bauckham has argued the New Testament doesn’t slowly promote Jesus towards deity over time—it places Him inside the identity of the God of Israel from the beginning, exactly as Isaiah 40–55 defines the identity.

So the case doesn’t rest on a handful of predictions that might be coincidence. It rests on this: the God Isaiah saw, and the man the apostles knew, are treated as the same person.

How Do We Know We’re Not Just Seeing Things?

The answer is a controlled method. We’re looking for types—real people, events or objects in the Old Testament that God designed in advance to point forward to Christ. A type isn’t a random resemblance. Geerhardus Vos described types as genuine anticipations planted by God in history, not decorations added later by clever readers.

John Calvin, who wrote a large commentary on Isaiah, was strict about this. He repeatedly warned against forcing meanings on to the text that the words themselves will not carry, and he had little patience for preachers who found hidden pictures everywhere. Edmund Clowney made the same point for modern readers: Christ must be found along the line of the text’s own promise, not smuggled in by imagination.

That gives us three simple tests before we claim a passage points to Jesus:

• Does the New Testament do it? Every connection in this post is one the apostles make first.
• Does it follow God’s promise line? The promise of a Saviour runs from Genesis 3 through Abraham and David to Christ. Types sit on that line.
• Does it come out of the text or out of our heads? Isaiah’s own words must support it—the flow, the images, the argument of the book.

Four Objections, Answered

“Isaiah 7:14 just means a young woman, not a virgin.”

The Hebrew word is ‘almah, which describes a young woman of marriageable age. Critics say it doesn’t have to mean virgin. But 3 things matter. First, Jewish translators—not Christians—rendered it with the Greek word parthenos, which does mean virgin, about two hundred years before Jesus was born. Second, the passage promises a sign, and an ordinary young woman having an ordinary baby isn’t a sign of anything. Third, the child is called Immanuel, “God with us”, which is a very large name for an ordinary baby. Edward Young argued the sign is addressed beyond King Ahaz to the whole house of David, which is why it can reach far past Ahaz’s lifetime.

“Christians read Jesus back into the text later.”

This would be a strong objection if Jewish readers before Christ had never read Isaiah as being about the Messiah. They had. The ancient Aramaic paraphrase of Isaiah, the Targum, actually inserts the word “Messiah” into Isaiah 52:13, where the Servant is introduced. Jewish readers saw a coming Messiah there long before any Christian did. What Christians added wasn’t the expectation—it was the identification.

“Isaiah had 2 or 3 different authors, so the ‘predictions’ were written afterwards.”

Many modern scholars split the book, mainly because Chapters 40–55 speak about the Babylonian exile as though it were present, and even name King Cyrus (44:28–45:1) roughly 150 years before his birth. The honest thing to say is this argument is mostly philosophical: it assumes in advance that no one can foretell a name. The textual evidence pulls the other way. The Dead Sea copy of Isaiah shows no break or seam at Chapter 40. And John 12 quotes Isaiah 53:1, then quotes Isaiah 6:10, and says Isaiah said both—treating the book as one man’s work and one man’s vision.

“The Servant in Isaiah 53 is the nation of Israel, not a person.”

This is the most serious objection, and it deserves more room than we can give it here. In short: the Servant is repeatedly distinguished from the nation—He suffers for “my people” (53:8), He is sinless while the nation is not (53:9), and He restores Israel rather than being Israel (49:5–6). We have answered this in full in a separate post.

How to Read Isaiah for Yourself

If you want to see this with your own eyes rather than take our word for it, do 3 things.

• Read Isaiah 6, then John 12:37–41. Ask yourself whose glory Isaiah saw.
• Read Isaiah 40, then Mark 1:1–4. Ask who the highway was being built for, and who walked down it.
• Read Isaiah 61, then Luke 4:16–21. Ask why Jesus stopped reading in the middle of a sentence.

Isaiah isn’t a book of scattered predictions that happen to fit. It’s 1 long answer to 1 question: how can a holy God save an unholy people without ceasing to be holy?

The answer is a child who’s called Mighty God, a Servant who is punished for crimes He never committed, and a Conqueror who returns for the family His death created. Isaiah saw Him from 700 years away and called it good news.

That’s why the nickname fits. Not a fifth account added to four—but the same good news, told first.
