What Jesus Said
“And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: That whosoever believeth in him should not perish, but have eternal life.”
Where It Comes From
“And the LORD said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live. And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.”
Original Language Note
The Greek "hypsōthēnai" (ὑψωθῆναι, "to be lifted up") carries a double meaning in John: it refers both to being lifted on the cross and to being exalted in glory. John uses this deliberately — the cross is Christ's exaltation.
The Context
Jesus spoke these words to Nicodemus, a Pharisee who came to Him by night. This conversation contains the famous John 3:16, but it opens with Jesus explaining the necessity of His death through the typology of the bronze serpent.
Seeing Christ
The bronze serpent was made in the likeness of the very thing that was killing the people — yet looking upon it brought life. So Christ was "made sin for us" (2 Corinthians 5:21) — made in the likeness of the very thing that destroys us — yet looking upon Him in faith brings eternal life. The serpent was lifted on a pole; Christ was lifted on a cross. The dying Israelites needed only to look and live; the spiritually dying need only to believe and live. The simplicity of the gospel — "look and live" — is embedded in this ancient story.
Answering the Skeptic
This passage demonstrates that Jesus understood His death as both necessary ("must be lifted up") and purposeful (to give eternal life to believers). It refutes claims that the crucifixion was an unexpected tragedy or defeat. Jesus explicitly says He "must" be lifted up, using the Greek "dei" (δεῖ) — divine necessity. The cross was not Plan B.
