Don't marvel that I said to you, 'You must be born anew.'
This interpretation (!) is typical of the gimmickry employed in vain efforts to talk the rite of baptism out of this passage and out of the whole New Testament.  Note the play upon the words "whence" and "when," as if the similarity of these words interchanged their meaning.  Can anyone believe that Jesus was here telling Nicodemus that he could not tell "when" the wind was blowing?  But the words rhyme!  So what?  "P" stands for pool; and "P" rhymes with "T" and "T" stands for trouble, right here in River City!  People do know WHEN the wind is blowing; and Christ also revealed the WHEN of the new birth; it is WHEN we are baptized into Christ.  As Paul said, "Being THEN made free from sin"  (Romans 6:17,18 KJV), that is, WHEN we have been baptized.  Paul was discussing Christian baptism in that passage, and he did not hesitate to make the Christian's baptism the exact moment, the THEN of his being made free from sin and becoming a servant of righteousness.  See my Commentary on Romans, p. 226.
