(John 3:14-16)
The discussion at Jerusalem between Jesus and Nicodemus
Who is called a “ruler of the Jews”. After speaking of the necessity of a man being born again before he could  “See the kingdom of God”, Jesus spoke also of “heavenly things” And of salvation and the condemnation of those that do not believe in Jesus.

14: “And as Moses lifted up the serpent in the wilderness, even so, must the Son of  man be lifted up:
15: That whosoever believe in Him should not perish, but have eternal life.”
16: For God so love the world, that he hath given His only Son, that none that believe in Him, should perish: but should have everlasting life.
