“again born of water is a idiom for natural birth in that day and culture”
Not in the Bible. Water symbolizing washing sin away. Been that way for 2,000 years. You must get away from Jimmy Swaggart and his crazy heretical nonsense.
So once again, and read it slowly because this comes after John 3:3.
“Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. John 3:5
verse 6 follows verse 5 and explains it
You read and even quote, but refuse to comprehend what was offered to you in agape. The Scriptures many times repeat the message so human beings can start to see that TRUTH is offered to them. Jesus did it with Nocodemus, yet you have chosen to twist the repetitions to suit the false religion of catholiciism framework. How sad for youa nd catholics in general, that your religion is doing what Jesus condemned int he Pharisees and Sadducees: “Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered.” Luke 11:52
