“And as Moses lifted up the bronze snake on a pole in the wilderness, so the Son of Man must be lifted up, so that everyone who believes in him will have eternal life” (John 3:14-15)

Judges 17:1-18:31
John 3:1-21
Psalm 104:1-23
Proverbs 14:20-21

As the bronze snake was a symbol of suffering, so Jesus foretold His intent to take on Himself the source of suffering for the world, which is man’s sin, by being lifted up on the cross.
