For 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.
In context
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. 17God did not send the Son into the world to judge the world, but so that through him the world might be saved. 18Whoever believes in him is not judged; whoever does not believe stands judged already, for not believing in the name of the only Son of God.
