Excellent example of following the way Jesus did things, where He shows that this is a metaphor to be understood according to the ways in which it does match reality and the ways in which it does not.
John 3:1 Now there was a man of the Pharisees, named Nicodeâ˛mus, a ruler of the Jews. 2 This man came to Jesus by night and said to him, âRabbi, we know that you are a teacher come from God; for no one can do these signs that you do, unless God is with him.â 3 Jesus answered him, âTruly, truly, I say to you, unless one is born anew, he cannot see the kingdom of God.â 4 Nicodeâ˛mus said to him, âHow can a man be born when he is old? Can he enter a second time into his motherâs womb and be born?â 5 Jesus answered, âTruly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7 Do not marvel that I said to you, âYou must be born anew.â 8 The wind blows where it wills, and you hear the sound of it, but you do not know whence it comes or whither it goes; so it is with every one who is born of the Spirit.â 9 Nicodeâ˛mus said to him, âHow can this be?â 10 Jesus answered him, âAre you a teacher of Israel, and yet you do not understand this? 11 Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen; but you do not receive our testimony. 12 If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? 13 No one has ascended into heaven but he who descended from heaven, the Son of man. 14 And as Moses lifted up the serpent in the wilderness, so must the Son of man be lifted up, 15 that whoever believes in him may have eternal life.â
So entering into his motherâs womb a second time? Jesus says no, that is taking the metaphor too literally.
For what the metaphor does mean, Jesus contrasts being born of the Spirit with being born of the flesh. He compares this with the contrast between heavenly things and earthly things. The implication is quite clear. When Jesus speaks of eternal life, He is not speaking of the deathless life of a vampire or zombies rising from the grave â or things which can be explained in everyday terms of physical life. He is talking about something spiritual (as God is spirit), other-worldly, and non-physical (in the sense not being of the laws of nature and the physical universe). Paul does the same thing in 1 Corinthians 15.
So this goes hand in hand with the story in Genesis where God says to Adam and Eve that on the day they eat of the fruit they will surely die and the serpent says they will not die. So on the day Adam and Eve ate of the fruit, did they die? Was God a liar and the serpent speaking the truth? They died in the same way that we are reborn⌠their spirits died and our spirit which was dead is brought back to life by being reconnected to the source of life which is God and given a new inheritance from God through the 2nd Adam to replace the contaminated inheritance coming to us through the 1st Adam.
