John 3:14-18

3:14 Just as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, 3:15 so that everyone who believes in him may have eternal life.”

3:16 For this is the way God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life. 3:17 For God did not send his Son into the world to condemn the world, but that the world should be saved through him. 3:18 The one who believes in him is not condemned. The one who does not believe has been condemned already, because he has not believed in the name of the one and only Son of God.

John 3:36

3:36 The one who believes in the Son has eternal life. The one who rejects the Son will not see life, but God’s wrath remains on him.
