Sometimes you read comments on John's baptism that liken it to the unorthordox practice developed by the Jews between the Old and New Testaments where they would immerse gentiles in rivers or in mikvah when they wanted to convert to the faith. They say that John practiced this same ritual, but was different in that he insisted unrepentant Jews be immersed as well as gentiles. This practice was not prescribed in the Old Testament and, being extra biblical, would have been considered heresy. Yet representatives from the Pharisees considered John's baptism as a ligitimate ritual prophesied to be performed by the Messiah or a prophetic forunner. They asked John why he was baptising if he were not "The Christ", "The Proffit" or " ElIjah". Therefore John's baptism was, unlike the Jewish ritual of immersing gentiles, something truly orthodox and prophesied to occur from the scriptures themselves.. Interestingly, when you search for prophisees about water purification to be performed just before the coming of the Messiah, instead of immersions, you find instead prophisees of numerous sprinklings and pourings. A few examples: Ezekiel 36:25-27 (ESV) I will sprinkle clean water on you, and you shall be clean from all your uncleannesses, and from all your idols I will cleanse you.  And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh.  And I will put my Spirit within you , and cause you to walk in my statutes and be careful to obey my rules. Isaiah 44:2-3 (ESV) Thus says the Lord who made you, who formed you from the womb and will help you: Fear not, O Jacob my servant, Jeshurun whom I have chosen.  For I will pour water on the thirsty land, and streams on the dry ground; I will pour my Spirit upon your offspring, and my blessing on your descendants. and that which they have not heard they understand. Isaiah 32:14-15 (ESV) For the palace is forsaken, the populous city deserted; the hill and the watchtower will become dens forever, a joy of wild donkeys, a pasture of flocks;  until the Spirit is poured upon us from on high, and the wilderness becomes a fruitful field, and the fruitful field is deemed a forest. Ezekiel 39:29 (ESV) And I will not hide my face anymore from them, when I pour our my Sprirtt upon the house of Israel, declares the Lord God." Isaiah 52:14-15 (ESV) As many were astonished at you— his appearance was so marred, beyond human semblance, and his form beyond that of the children of mankind—  so shall he sprinkle many nations ; kings shall shut their mouths because of him; for that which has not been told them they see, Joel 2:28 (ESV) "And it shall come to pass afterward, that I will pour out my Sprirt on all flesh; your sons and your daughters shall prophesy, your old men shall dream dreams, and your young men shall see visions. Isaiah 52: 15 was part of the discourse being read by the Ethiopian Eunuch when he requested baptism from Phillip, and was, along with Joel 2:28, prophetic of the baptism of the Holy Spirit which fell on the Apostles at Pentecost. Acts 2:17. Concerning this pentestostal experience, John had told the people that as he baptized with water, so the Lord Jesus would baptize with the Holy Spirit. Lk. 3:16. The Lord himself said to His desciples in Acts 1:5---- 5 for John baptized with water, but you will be baptized with the Holy Spirit not many days from now." When this "Spirit baptism" occurred, it was describided consistantly to be " poured out ", Acts.2:17-18, 33. Peter said," the Holy Spirit fell upon all who heard the word" Acts. 10:44 and the Jews were, "astounded that the gift of the Holy Spirit had been poured out even on the Gentiles" Acts 10: 45. Then he said, "Can anyone withhold the water for baptizing these people who have received the Holy Spirit just as we have?"Acts 10: 47. To put it simply, Jesus said He was going to do with the Holy Spirit the very same thing to His desciples that John had done with water! In view of these facts, what other logical conclusion can you come to other than — JOHN THE PRESBYTERIAN POURED THE WATER!
