Pretty standard for "movements", which NAACP was an outgrowth of. They grow beyond their original purpose to become a self-feeding bureaucracy that exists to further itself. If they acknowledged they were successful in the original goal and shut down it would be one thing - the right thing. But they never do.

People have the same problem, which is of course why it exists in movements/movement-centric organizations. They wrap their identity into the role, and cannot separate it. We've all head, I suspect, about the fireman turned arsonist to be the one to save people from a fire, but likely don't think about other jobs.

Consider a "child protection services" worker. Once they identify themselves as being there "to save children" all children become in "need" of being saved. They see their role as believing whatever they need to to think the kid needs their help. We see it in cops who become overbearing allegedly to "protect you" and violate your rights under the claims of " just doing a welfare check."

The NAACP, like unions and HOAs, have outlived their usefulness to their original purposes and have become a shell of their former self, perverted to serving the self-glorification of the people who take it over.

They aren't terribly detailed about it, but from my understanding (been years since I studied it in depth), it will seem to the person to be instant, but much time will have passed. Kind of like going to sleep and waking up the next day - or being in a coma for years.

It is known as the "eschatological gap" but has a parallel. To possibly oversimplify it:
The early christian theologists thought judgement day was soon - imminent even. Thus they didn't really think about it as something that may be thousands of years from their time. As a result of that thinking they wrote about dying, then having a big judgement day when you'd be resurrected into a new body representing which "way" you went.

That language is perhaps surprising to some, but it is true that early christians did not reject reincarnation, so the idea that you'd be reincarnated to a new body was not perceived as being at odds with the basic theology.

So much of that language is around there being a period of "limbo" where you are not conscious at all until judgement day. But then it became apparent that judgement day was not nigh. Because they didn't expect it to take long they didn't think through the process, and left it vague.

This is similar to the Marxists of the early 20th century realizing Marx' inevitable and pending spontaneous revolution was not going to happen - at all. So they reworked their belief in to a local revolution - Mussolini being one of the first to pioneer this at the government level.

So for hundreds of years, until the second Constantinople Council IIRC, reincarnation was an accepted part of Christianity - for some that was to solve the problem of not going to heaven immediately. IIRC the term used was apocatastasis which is essentially "die and reincarnate to work out your bad karma until you're as pure as Christ." IIRC the Gnostics were quite adherent to that belief. For the catholic church's solution they asserted the soul did not exist prior to your quickening (the moment a pregnant woman can feel baby's movement in the womb), thus precluding apocatastasis and reincarnation as a whole.

Yet they still struggled with trying to interpret the alleged rules that came from that. Combined with the notion that we are all born in sin, the question of "what about babies who die" became a problem, as did people who had repented but still felt guilty. This is where the ideas of Limbo and Purgatory came from: trying to resolve the dissonance of "a baby has committed no sin, why should it go to hell?" and similar questions around repented people. Included in that dissonance set are people who were goo people but did not live in a society that knew about "the only way to heaven" at all.

It was all quite messy, as you'd expect looking at it from the future. So to answer your question: "it depends." ;) But ultimately when you look at original scripture at no point does it speak of things like going up or down immediately or that your ancestors are "looking down from above" after they die, and similar claims modern christians hold fast to - completely unaware they contradict the actual gospels. :P
