True its all tied up in language and languages.. Most know only one language and that one not very well.. God(Father), Jesus, Holy Spirit even our own spirit transcends language.. Something spiritually discerned can transcend any language barrier.. Language is a barrier..
A "name" is just a "handle" anyway like Alamo-girl, Joe, Louie, same thing.... An address for a personality.. Baretta(of TV sitcom cop show fame) called God "Louie".. as he looked up.. LoL.. Why not.?.. if its in reverence..
Some think God can see them naked and is not offended.. I say God sees you naked to your spirit, the body is just clothing.. and is clothing to God..
NOW THATS NAKED brother, ugh,, sister.. God sees you in a way most cannot see themselves.. He sees your spirit.. and the desires of your spirit.. Most people don't like being naked.. If they knew how deeply God sees them, it might freak them out.. Same while we are praying.. Being born again just starts a phase of a humans life when he might actually find out WHO HE IS.. Who his spirit is.. his body is just clothing.. Who we are is much deeper than a body.. much deeper than a "name".. And really much deeper than even we know about, our spirit.. Until God reveals it to us.. The spirit even transcends gender.. Gender is a qualia of the body..
My recommendation is all get re-born if only to find out who they really are.. being reborn spiritually is just a starting point.. as the metaphor implies..
He even sees all the stuff you're hiding from yourself...and every now and then makes you take a closer look....(been there, done that, expect it'll happen again!)
