Two waters are at issue here--liquid waters and invisible gaseous waters. These two states of waters are emphasized, beginning at Moses, and in the prophets, and in the Psalms, all referencing THE WORD OF GOD. 

The "liquid" waters always typifies Jesus Christ--that WORD of God in the visible flesh on earth under the firmament, just as liquid water is located only on earth under the firmament. The gaseous waters are typical of the invisible eternal spirit WORD of God. That liquid water is personalized in the Jordan river which passes down through the land of Israel into Judah seeking out the lowly and into the Sea of Galilee (representing the people, nation and tongue of Israel), and finally where it deposits the impurities from the earth into the Dead Sea, leaving those impurities there when it ascends out of the Dead Sea in it's invisible gaseous form again. 

This typifies Jesus as coming from above and becoming visible in the flesh as the Jewish Son of man/Son of God/Seed of the woman, who passes through the land of Abraham, Isaac, Jacob, Judah, and David seeking out the lowly rather than the elevated. His destiny as the (liquid waters) Messiah was always toward His "death," "burial," "resurrection," and "ascension." That ascension was in a new spirit form of eternal man. This insures that he will come again to receive all those who believe in His work of redemption for the sin of mankind.   

The visible liquid waters are those that John baptized with. Jesus, however, was to baptize with the HOLY GHOST--the waters which Jesus emphasized were living invisible moving gaseous waters that He described as the "wind" that "bloweth". 
  
John, the Baptist stressed this point over and over again. Jesus, Himself, repeatedly declared the same thing. See: [God’s Day-One Creation, A Type of the Word of God, Pages 19-29][1] for many references.
