Serpent On A Pole

Joh 3:13  No one has ascended to heaven but He who came down from heaven, that is, the Son of Man who is in heaven. 

Joh 3:14  And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, 

Joh 3:15  that whoever believes in Him should not perish but have eternal life.
