Serpent

13No one has ascended into heaven but he who descended from heaven, the Son of man. 14And as Moses lifted up the serpent in the wilderness, so must the Son of man be lifted up, 15that whoever believes in him may have eternal life." 16For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life. 17For God sent the Son into the world, not to condemn the world, but that the world might be saved through him. John 3:13-17
