“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.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.” John 3:14-18
Here Jesus talks about Himself the Son of man. He says that as Moses lifted up the serpent in the wilderness, so He must be lifted up. What is He talking about? Numbers 21 gives the account of God telling Moses to make a serpent of brass. Why did God do this? Earlier the people sinned against the Lord, and so He judged them and sent poisonous snakes among them, and they bit them. But the Lord was merciful. He told Moses to make a brass serpent on a pole, that anyone who looked on it would be healed. If people believed God and turned to look they would be healed.This represents Jesus.
Why was it a serpent on a pole? The people were bitten by serpents. It represented the judgment of God. Jesus on the cross shows the judgment of God. God couldn’t let sin go unpunished. And even when our sins were placed on His only begotten Son Jesus, God judged.
But like the brass serpent was for healing and not for condemnation, so the Father didn’t send Jesus into the world for condemnation. He sent Him to be a Saviour. If we just look to Jesus, acknowledge our sinfulness, and ask for forgiveness, we will be healed.
Just like the people bitten by the snakes were already doomed to die, so is every one of the human race condemned already who hasn’t trusted Jesus as Saviour.
“ For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.” John 3:17-18
“Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:” Romans 5:12
Jesus says, “ . . . I am the way, the truth, and the life: no man cometh unto the Father, but by me.”(John 14.6).
“How shall we escape, if we neglect so great salvation . . .” (Heb 2.3).
Unless we ask Jesus to save us, we will have to face the judgment of God.
