Jesus and the Brazen Serpent

In John 3, Jesus makes a claim about his cross that should have staggered any first-century Jewish scholar: “And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life” (John 3:14–15).

Of all the typological images Jesus could have selected from the Torah to explain his execution, this is the most jarring. He does not compare himself to the Passover lamb. He does not compare himself to the scapegoat on Yom Kippur. He compares himself to the snake.

To understand why, you have to look down the timeline of biblical history, past Golgotha and into the deep logic of how the Apostle Paul understood the atonement. What happened on the cross was not just a substitutionary penalty. It was an act of cosmic subversion.

The Image of the Curse

The original story is recorded in Numbers 21. Israel rebels against God and Moses in the wilderness. In response, God sends “fiery serpents” (nehashim seraphim) among the people.¹ The venom begins to take its toll. The people beg for rescue.

God’s solution is strange. He doesn’t remove the serpents. He tells Moses to make a bronze serpent (nahash nehoshet)² and set it on a pole.³ “And if a serpent bit anyone, he would look at the bronze serpent and live” (21:9).

The mechanics of this rescue are profound. The Israelites are dying from snake venom. The cure is to look at the very image of the thing that is killing them, now subjected to the wood, immobilized and defeated. The source of death becomes the icon of life. Even the intertestamental Jewish writers recognized the sheer theological weight of this event. In the Wisdom of Solomon, the author reflects on the bronze serpent and writes, “For he who turned toward it was saved, not by the thing that he saw, but by you, the Saviour of all” (Wisdom 16:7).

Becoming Sin

When Jesus tells Nicodemus that he must be “lifted up” exactly like that bronze serpent, he is forecasting the deepest mystery of the cross.

Paul writes in 2 Corinthians 5:21: “For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.” Notice the verb. God did not simply place sin upon Jesus. He made Him to be sin.

Paul says it again in Romans 8:3. God sent his own Son “in the likeness of sinful flesh” and “condemned sin in the flesh.”

At Golgotha, Jesus does not just bear the punishment of the fallen world; he absorbs its very nature. He takes the rebellion, the violence, the accusation, and the venom of the serpent of Genesis 3 into his own body. As Paul writes in Galatians, “Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, 'Cursed is everyone who is hanged on a tree'” (Galatians 3:13). He doesn't just bear the curse. He becomes the curse itself.

Exhausting the Venom

As we have explored elsewhere, the crucifixion scene is framed by two revolutionaries on his right and left. The man on the left — the impenitent thief who mocks Jesus — occupies the prophetic position of the fallen cherub, the archetypal rebel. That thief embodies the demands of the Accuser: “Save yourself and us, if you are the Christ!” (Luke 23:39).

But Jesus does not argue with the Accuser. He does not fight the venom. He lets it strike him. He pulls the entirety of the serpent’s power into Himself and lets the poison kill Him.

Paul describes the aftermath in Colossians 2:15: “He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him [the cross].”

How did he disarm them? By letting them use all of their ammunition. When a serpent strikes and empties its venom glands into its prey, it is temporarily harmless. Jesus absorbed the lethal dose of the world’s sin so completely that death itself ruptured. He exhausted the venom.

When Moses lifted up the serpent in the wilderness, the people looked at the image of their death, pinned to a pole, and lived. When Jesus was lifted up, he pinned the ancient serpent to the cross by absorbing its strike. He became the bronze serpent. The thing that was killing humanity was immobilized on the wood, and through its defeat, we are healed.

The Place of the Skull

This showdown with the cosmic serpent also illuminates the deliberate geography of the crucifixion. All four Gospels emphasize the Aramaic name of the hill where Jesus died: Golgotha, the Place of the Skull (John 19:17).

To a Hebrew ear, Golgotha shares a ringing phonetic resonance with another famous biblical name: Goliath. In 1 Samuel 17, David strikes the giant in the forehead, sinking the stone into his “skull” (gulgoleth, the linguistic root of Golgotha). The text notes that David cut off the giant’s head and brought it to Jerusalem (17:54). Ancient tradition suggests that Golgotha — the hill just outside Jerusalem — was named after the buried skull of that great enemy.

But the typology goes deeper than wordplay. In 1 Samuel, the writer deliberately describes Goliath’s armor as a coat of “scales” (qasqasim), the exact Hebrew word used elsewhere to describe river monsters and fish. Goliath is depicted theologically as a serpent on land — a terrestrial Leviathan.

When Jesus goes to the cross, he goes to the Place of the Skull. He goes to the hill of the serpent. In Genesis 3:15, God spoke the first promise of the gospel to the serpent in Eden: He shall bruise your head, and you shall bruise his heel.

At Golgotha, Jesus fulfills both halves of the prophecy simultaneously. He allows the venom to strike his heel. The early church father Gregory of Nyssa described this subversion utilizing the image of the “Divine Fishhook.” Christ's humanity was the bait, and his divinity was the hook. When the great terrestrial Leviathan swallowed the bait of his death, the hook of his indestructible life destroyed the beast from the inside out. By absorbing the blow, he drives the wood of the cross directly through the Skull.

The Idol of Nehushtan

But there is a dark coda to the bronze serpent narrative, and it contains a profound typological warning. Centuries after Moses, King Hezekiah had to destroy the bronze serpent because the Israelites had begun burning incense to it (2 Kings 18:4). They called it Nehushtan (a wordplay combining "bronze" and "serpent"). The means of salvation had become an object of worship in itself — the instrument was venerated while its purpose was forgotten.

The warning is clear: do not worship the mechanism while restricting its purpose. The bronze serpent was lifted up to heal everyone who was bitten. The text of Numbers 21:8 says, “everyone who is bitten, when he sees it, shall live.” The remedy was exactly as universal as the venom.

The Condition of Looking

But a powerful objection is often raised here: the bronze serpent only healed those who actually looked at it. Doesn't this mean salvation is strictly conditional? That the cross only saves those who choose to look, leaving the rest to perish in the wilderness?

To answer this, we have to trace the specific word Jesus uses in John 3:14 across his ministry. The Greek word for “lifted up” is hypso&omacron;. This is a deliberate echo of the Suffering Servant in Isaiah 52:13, who “shall be high and lifted up [hypsoo].” But Jesus doesn't just use this word once. He builds a chain across the Gospel of John, claiming the title three times.

First, “the Son of Man must be lifted up” (John 3:14). Second, Jesus tells his accusers, “When you have lifted up the Son of Man, then you will know that I am he” (John 8:28). The phrase "I am he" is ego eimi—the Greek translation of the sacred, unpronounceable divine name. Jesus is claiming that the ultimate revelation of the identity of the one true God happens precisely at the moment the Son is nailed to the wood like a cursed thing. But the third occurrence is the climax, and it answers the conditionality of looking.

Jesus declares: “And I, when I am lifted up from the earth, will draw all people to myself” (John 12:32).

John 3:15 establishes the condition: "that whoever believes in him may have eternal life." Skeptics of universal restoration often point to this as an indicator of a limited salvation. After all, looking is absolutely required for healing. But what John 12:32 establishes is the certainty that this condition will be met. Christ guarantees that the sheer gravitational power of his being “lifted up” will eventually succeed in drawing the eyes—and the hearts—of the entire cosmos to himself. The bronze serpent was physically lifted up so that all who were dying could look at it. Christ was lifted up to ensure that all who are dead in sin will ultimately look to him, believe, and live.

When we limit the scope of the cross—when we teach that the atonement is only for some, or that its power to draw all people will ultimately fail—we are venerating a theological Nehushtan. We turn the living, universal reality of salvation into a limited bronze idol. The type demands nothing less.

Out of the Night

It wasn't an abstract theory for the man who first heard it in the dark. Years after Jesus told Nicodemus about the bronze serpent, that cautious Pharisee finally stepped out of the night. John records that Nicodemus came to Golgotha, bringing seventy-five pounds of myrrh and aloes to bind the broken body of his Lord (John 19:39). He stood at the foot of the pole. He stared at the image of the curse. And like everyone else the cross will ever draw, he looked and lived.
