Born again is not what Christ said. Christ said born from above... Meaning at conception a ‘soul/spirit’ is placed in the womb. And only those that take this flesh journey pass the first requirement to ‘see the kingdom of God’. Born again is a slogan that does not fit with what Christ was teaching... Check out the book of Jude.... there are some that refuse to take this flesh journey and they are call the Sons of God in Genesis and fallen angels elsewhere. And they like the devil have already been judged to death.
John 3:13 explains what Christ was teaching.” And no man hath ascended up to heaven, but He That came down from heaven, even the Son of man Which is in heaven
Not patching an old garment with new cloth, and not putting new wine into old bottles—both metaphors would seem to describe a different kind of being born again, the kind most people accept as being the meaning.
