To be honest, I've never really understood this part: "A: It is not that those who endure to the end will be saved, but that those who endure to the end shall save others. It is your choice to be among those who choose to be a part of the vanguard of the new reality!!!"
I mean, if everything is a lesson and the realm we currently inhabit is a STS environment which serves as a classroom, just as there must be STO environment who also serve as classroom, what do people need to be saved from? The threads about the after-life shows that damnation doesn't exist quite in the way it is written in holy books, so it's not damnation people would need to be saved from, I guess?
There is the suggestion in some of the afterlife literature (and quoted on that thread), that there are places that are less than pleasant where people naturally fit because of their reluctance and resistance to seeing - and positively responding to - reality, and ways of being at higher, more STO, levels. And it does seem to be part of the job description of more evolved STO people in that environment to assist those in the dimmer areas when an opening to get them the hell out of there (no pun intended) arises. But all of those considerations seem to be secondary to the task at hand I think; that being to survive or "be saved" oneself - as a result of the efforts involved in helping others along with this process in the here and now. In other words, having as one's aim to help others can be much more powerful and viable a reason for being than we might presently imagine.
There have been a number of instances where the suggestion of how to do this, and why it works, have been given. One main one being that giving others - what one's self most needs - actually helps one to strengthen, and grow. And helps mitigate one's own difficulties. The challenge, given that we exist in a morass of lies and programming, would seem to be how well we can be proactive in responding to this shared state of affairs - body, mind and soul; how motivated we can be to help others when so much of our reality is working to pull us towards the nihilistic world view, among other entropic forces.
As for the physical world, there have been many civilisations before ours and my current feelings is that we will end just like them. And the few who survive might become the enigmatic figures of our past such as the likes of Zarathustra or become the new people to leave drawing in caves so to say. And ultimately, the new civilisation to come after ours will be wiped and so on and so forth because such is the nature of this realm (or at least that's my current understanding so far).
Unless, perhaps what people need to be saved from is reincarnation is this particular realm?
Another way to look at it may be: why stay in grade school when, in the cosmic sense of things, we can act on the opportunity to go to University where the learning is, in potential, exponentially and quantum levels higher? We may very well have a long way to go till we get there, but I sometimes think we take for granted just how far we've come, and how much knowledge and awareness has brought us to where we now presently are.
