The water is the word of God. We're washed in the word by hearing and through hearing and believing our faith grows then once we truly live by the word of God and obey the commandments of Jesus in the gospels, God will bless us with the holy spirit and cleanse us from within. We must be born again of the spirit to enter into the kingdom of God not just by hearing the word but by living by it, through the spirit being refreshed and cleansed within by the rivers of living water every day.
You must be born of water and Spirit. Jesus ain't say you must be born of His words. If He did it woulda just said just that. Beacuse His words are Spirit. He said be born of water and Spirit. John 3:5 Jesus 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. ; He said WATER.!! Not words.
