With some emphasis on a few words:
John 3
[SUP]3 [/SUP]Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
[SUP]4 [/SUP]Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?”
[SUP]5 [/SUP]Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
So now, the point comes to what is the water referred to?
a) For those born of the Spirit can see.
b) But to Enter requires both water and the Spirit
And there is a distinction between (a) and (b) but virtue of the fact that one "sees" whereas the other "enters".
All those in (a) had a natural birth anyway. So the explanation for water being natural birth cannot be the real explanation.
So ---- what is the "water" referred to? Herein lies the clue. For we know that "salvation" will mean to "enter"
