John 3:13-17

No one has gone up into heaven, but there is One who came down from heaven, the Son of Man [Himself—whose home is in heaven]. Just as Moses lifted up the [bronze] serpent in the desert [on a pole], so must the Son of Man be lifted up [on the cross], [Num 21:9] so that whoever believes will in Him have eternal life [after physical death, and will actually live forever]. “For God so [greatly] loved and dearly prized the world, that He [even] gave His [One and] only begotten Son, so that whoever believes and trusts in Him [as Savior] shall not perish, but have eternal life. For God did not send the Son into the world to judge and condemn the world [that is, to initiate the final judgment of the world], but that the world might be saved through Him.
