John 3:3-5 Womb

This explanation of John 3:3-5 makes some sense, Baptism isn't to be a born again Jew, but a Christian.

Understanding that the term “born again” referred to a conversion to Judaism sheds light on the conversation between Yeshua (Jesus) and the sage Nicodemus in the Book of Yochanan (John).

Nicodemus wondered, “How can a man be born when he is old?  He cannot enter a second time into his mother’s womb and be born, can he?”  (John 3:4)

From his Jewish perspective, Nicodemus essentially asked, “How can I convert to Judaism if I am already a Jew?”

Yeshua answered, “A man must be born of water and spirit.”  (John 3:5)

He was explaining to Nicodemus that we cannot rely on our “Jewishness” (or any other heritage) to enter the kingdom of heaven.  A conversion of our spiritual condition is necessary for salvation.

Though this website teaches immersion for baptism, it also gives the wrong impression that Baptism should bring us back to keeping the law. Christian baptism should be seen as seperate from the law and doesn't rejoin us to Judaism.
