The gestalt of identity is what being born again is all about.. Do you identify with the "flesh" or do you identify with the "spirit"/Spirit?.. What "are" you?.. Flesh?... spirit?.. both or neither?.. What is at stake is not only your lifestyle.. but the spirit of your awareness..
When you look into a mirror do you see yourself?.. or merely the container of yourself?.. Are you happy with the packaging or do you want(seek after) the contents of the packaging.. Large questions requiring answers about "identity"..
What is God, Angels, spirits, demons, the devil? are distant answers to personal identity.. cause what "you" are determines what those things(beings) are.. in your world..
Personal Indentity is at the base of who you think you are.. Metaphorically being born again is mandatory to your world view.. What Hegel missed (I think) is after becoming sure of who you(anyone) think you are.. you might be WRONG!.. I love the verse of I Cor 2;9..
Identifying with God (on any level) is a mind blowing event..
Are you a primate?... or something else entirely..
