No, I didn't. The point is, and was, that Nicodemus understood the word to mean "born again" thus his reference to his mother's womb.
You're still missing it.
Yes, we see Nicodemus understood it is a context of again, but, he had a physical context in view.
But the context was not Nicodemus', it was the Lord's. Look at the conversation:
John 3
King James Version (KJV)
1 There was a man of the Pharisees, named Nicodemus, a ruler of the Jews:
2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
A few things to consider:
1. From Nicodemus' perspective the context is in regards to Christ being known as coming from God.
2. Christ's response is in a context of Kingdom Restoration.
3. These are not unrelated as many commentators on this passage suggest.
4. Based on the following context, what Christ is saying is...
"...you can't possibly know that I am come from God."
And then He tells him (Nicodemus) why. Because he (Nicodemus) is not...born of God.
Again, Nicodemus' understanding is physical, as was everyone's who awaited the Kingdom of God and the Messiah.
Jesus then validated that understanding by saying "that which is born of the flesh is flesh."
You stand alone in saying that the Lord "validated" Nicodemus' response:
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7 Marvel not that I said unto thee, Ye must be born again.
8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
9 Nicodemus answered and said unto him, How can these things be?
10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?
Nicodemus' physical understanding of the statement is rebuked, and a contrast drawn between what is born of flesh and what is born from above/of God/of the Spirit, all three the consistent teaching concerning regeneration, it is God Who performs this in the lives of men.
Had the meaning been "born from above" He would have had to say "that which fell from above is - well, uh, from above."
There is absolutely no provision in the text to support a concept of "falling." In view is a generation, so to speak, tied to the concept of birth.
"From above" correlates to being born of the Spirit. The "water" also correlates to the Word of God, as we are begotten of God by the Word:
1 Peter 1:23
King James Version (KJV)
23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
James 1:18
King James Version (KJV)
18 Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures.
Christ correlates the cleansing spoken of in relation to regeneration (see Ezekiel 36:25) as well...
John 15
King James Version (KJV)
3 Now ye are clean through the word which I have spoken unto you.
...which does not necessitate regeneration at this time (for the Mystery of the Gospel is as of yet unrevealed) and does not nullify the future events yet to unfold...
John 17:17-19
King James Version (KJV)
17 Sanctify them through thy truth: thy word is truth.
18 As thou hast sent me into the world, even so have I also sent them into the world.
19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.
Words mean things. Language means things (semantics). Meaning has meaning (general semantics).
That is correct. And the bottom line is that Nicodemus' understanding was physical, and his response rebuked. We do not ascribe any understanding to Nicodemus' response, because Christ did not.
God bless.
