Hello Hank. I'm no 'Greek guy', don't know about Granville-Sharp, but I agreed with this in post #14. I believe it could read 'Except one be born of water even the Spirit'.
Wind, water, I agree are indeed common metaphors or symbols for the Spirit. Fire, on the other hand, is by far and away primarily the metaphor/symbol most commonly used for the wrath of God.
7 But when he saw many of the Pharisees and Sadducees coming to his baptism, he said unto them, Ye offspring of vipers, who warned you to flee from the wrath to come?
8 Bring forth therefore fruit worthy of repentance:
9 and think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
10 And even now the axe lieth at the root of the trees: every tree therefore that bringeth not forth good fruit is hewn down, and cast into the fire.
11 I indeed baptize you in water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you in the Holy Spirit and in fire:
12 whose fan is in his hand, and he will thoroughly cleanse his threshing-floor; and he will gather his wheat into the garner, but the chaff he will burn up with unquenchable fire. Mt 3
A closer scrutiny of the context of Mt 3 should show that fire is NOT being used as a metaphor/symbol for the Spirit, but is in reference to WRATH. This is the prophet John the Baptist speaking to his fellow countrymen, to who he was sent.
Speaking to the Pharisees and Sadducees, “Who warned you to flee from the wrath to come?” John was referring to that wrath that was to come upon 'that generation' of Jews (“even now the axe lieth at the root of the trees” and, “the chaff he will burn up with unquenchable fire”).
“ ..he shall baptize you in the Holy Spirit and in fire...”. And that's exactly what Christ did to that generation of Jews that He walked among and preached to. To those that received Him, He gave the Spirit. Those that rejected Him had only that certain expectation of wrath to come.
Behold then the goodness and severity of God.....Ro 11:22
