“the flesh is flesh, and that which is born of the Spirit is spirit.”

9 months in the womb floating in abiotic fluid (water)birth of flesh. It is not like Jews were ignorant of rebirth metaphor redeemed infant, become adult, marriage, a teacher, teacher of teachers and Nicodemus couldn’t covert or become the king. So what is his dilemma?

[Ezekiel]

Sometimes people get so bogged down in "spiritual" meanings (or even arguing about them) that they lose sight of the spiritual, when there's

a new lease on life
second chance
fresh start

But then the point is to apply the message and move forward with a new attitude, perspective, focus, faith.
