The parallel seen in all detailed conversion accounts is clear. Both water baptism in the name of Jesus, and receiving the Holy Ghost were recorded. The conversion experiences align with Ezekiel 36:25-27, where God promises to sprinkle clean water to cleanse His people and put a new Spirit within them. Jesus criticizes Nicodemus for being a teacher of Israel and not understanding this.Wrong understanding there. Man is born of water (woman's water breaks during birth) and of Spirit (reborn through Holy Spirit baptism upon repentance.)
You people always leave out verse 6:
5Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
6That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7Marvel not that I said unto thee, Ye must be born again.
Also, if Jesus meant one's natural birth there would be no need for this stipulation. Think about it. Unless you are born, and born of the Spirit you can not enter the kingdom of God?
