Hi,
It sound strang to me .. because the 144 000 myth is like 607 myth or 1914 , it's a foundation of Jehovism ...
If GB change the "litteral" meaning to a "imaged" meaning ... they are cutting the branch where they are sitted.
How will they can say "we are the anointed GB" ??" since they are part of 144 000 ?
In such a same way if the meaning of 144 000 change, in some way it's the 1914 significance could change ...
because 1914 is the moment When Christ invisibly come back and begun to gather the anointed ... if they are not ... what could jesus gather ?
and finally ... if nothing more than the return of jesus lie on 1914 ... it's an open door to à 607 change since there is less and less reason for 1914 ....
But maybe I'm wrong :)
Best regards
