Jesus said to Nicodemus:

‘The Son of Man must be lifted up
as Moses lifted up the serpent in the desert,
so that everyone who believes may have eternal life in him.
Yes, God loved the world so much that he gave his only Son,
so that everyone who believes in him may not be lost
but may have eternal life.
For God sent his Son into the world
not to condemn the world,
but so that through him the world might be saved.
No one who believes in him will be condemned;
but whoever refuses to believe is condemned already,
because he has refused to believe in the name of God’s only Son.
On these grounds is sentence pronounced:
that though the light has come into the world
men have shown they prefer darkness to the light
because their deeds were evil.
And indeed, everybody who does wrong
hates the light and avoids it,
for fear his actions should be exposed;
but the man who lives by the truth comes out into the light,
so that it may be plainly seen that what he does is done in God.’
