John 3:12-16 NIV

[12] I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things? [13] No one has ever gone into heaven except the one who came from heaven—the Son of Man. [14] Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up, [15] that everyone who believes may have eternal life in him.” [16] For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
