In context
12If I have told you about earthly things and you do not believe, how will you believe if I tell you about heavenly things? 13No one has gone up into heaven except the one who came down from heaven — the Son of Man, who is in heaven. 14And just as Moses lifted up the serpent in the desert, so must the Son of Man be lifted up, 15so that everyone who believes in him may have eternal life. 16For God loved the world so much that he gave his only Son, so that everyone who believes in him may not perish but have eternal life.
