12 If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things?
13 No one has ascended into heaven except he who descended from heaven, the Son of Man.
14 And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up,
15 that whoever believes in him may have eternal life.
16 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
17 For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.
18 Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
