John 3:14 WEB

¹²  If I told you earthly things and you don't believe, how will you believe if I tell you heavenly things?

¹³  No one has ascended into heaven, but he who descended out of heaven, the Son of Man, who is in heaven.

¹⁴  As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up,

¹⁵  that whoever believes in him should not perish, but have eternal life.

¹⁶  For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.
