Believe in Jesus

Jesus said to Nicodemus:
“No one has gone up to heaven
except the one who has come down from heaven, the Son of Man.
And just as Moses lifted up the serpent in the desert,
so must the Son of Man be lifted up,
so that everyone who believes in him may have eternal life.”

For God so loved the world that he gave his only Son,
so that everyone who believes in him might not perish
but might have eternal life.
For God did not send his Son into the world to condemn the world,
but that the world might be saved through him.
(Jn 3:13-17)
