Jesus answered, “I assure you and most solemnly say to you, unless one is born of water and the Spirit he cannot [ever] enter the kingdom of God. [Ezek 36:25-27] That which is born of the flesh is flesh [the physical is merely physical], and that which is born of the Spirit is spirit. Do not be surprised that I have told you, ‘You must be born again [reborn from above—spiritually transformed, renewed, sanctified].’ The wind blows where it wishes and you hear its sound, but you do not know where it is coming from and where it is going; so it is with everyone who is born of the Spirit.”
Nicodemus said to Him, “How can these things be possible?” Jesus replied, “You are the [great and well-known] teacher of Israel, and yet you do not know nor understand these things [from Scripture]? I assure you and most solemnly say to you, we speak only of what we [absolutely] know and testify about what we have [actually] seen [as eyewitnesses]; and [still] you [reject our evidence and] do not accept our testimony. If I told you earthly things [that is, things that happen right here on earth] and you do not believe, how will you believe and trust Me if I tell you heavenly things? 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. Whoever believes and has decided to trust in Him [as personal Savior and Lord] is not judged [for this one, there is no judgment, no rejection, no condemnation]; but the one who does not believe [and has decided to reject Him as personal Savior and Lord] is judged already [that one has been convicted and sentenced], because he has not believed and trusted in the name of the [One and] only begotten Son of God [the One who is truly unique, the only One of His kind, the One who alone can save him]. This is the judgment [that is, the cause for indictment, the test by which people are judged, the basis for the sentence]: the Light has come into the world, and people loved the darkness rather than the Light, for their deeds were evil. [Is 5:20] For every wrongdoer hates the Light, and does not come to the Light [but shrinks from it] for fear that his [sinful, worthless] activities will be exposed and condemned. But whoever practices truth [and does what is right—morally, ethically, spiritually] comes to the Light, so that his works may be plainly shown to be what they are—accomplished in God [divinely prompted, done with God’s help, in dependence on Him].”
