I dunno. Rev. 7:9 talks about a great crowd that cannot be numbered. That's sounds different than a group of 144,000 (figurative or not) to serve as kings.
I'm not suggesting for a moment that I agree with the JW spin on this. Maybe my thinking is still being influenced by a life of indoctrination. But when I read these scriptures I see two different groups. So we all go to heaven to do our heavenly things but only a few are selected to serve with Christ. Maybe.
I dunno. Anymore, this stuff just gives me a headache.
