A connection in Scripture
The Bronze Serpent and the Cross
Why they are connected
Jesus makes the comparison Himself, the night He speaks with Nicodemus: 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. Healing came not by striving but by looking. So it is with the cross.
The Scripture behind it
“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.”Numbers 21:9
“And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:”John 3:14
“That whosoever believeth in him should not perish, but have eternal life.”John 3:15
Who has recognized it
The connection is Jesus' own, spoken in John 3 and applied directly to His crucifixion. It is one of the clearest cases of Jesus reading an Old Testament event as a picture of Himself.
Where readers differ
Interpreters discuss the details, why a serpent, in what sense Jesus is like it. But the link itself is not a later invention; Jesus states it plainly.
Why it matters for seeing Christ
It means salvation is not earned by effort but received by looking. The dying were not told to fight the snakes or climb to the pole; they were told to look and live. To everyone too weak to save themselves, the cross says: look to Him, and live.
Questions people ask
What does the bronze serpent have to do with Jesus?
In John 3:14 Jesus compares Himself to the bronze serpent Moses lifted up in Numbers 21. Just as those who looked at it lived, whoever looks to Christ lifted up on the cross in faith receives eternal life. Jesus makes the connection Himself.
What does lifted up mean in John 3?
Jesus says the Son of Man must be lifted up as Moses lifted the serpent. In John's Gospel being lifted up refers to the crucifixion, so Jesus is pointing to His own cross as the place people look to and are saved.
