Yep. Paul says the Gospel of the grace of God is, itself, the power of God unto salvation. That means what God wants to be believed unto salvation can be believed and will save any who believes it, no matter what language it's translated into because the Message itself is the power, not any particular translation of the message.
Now, Nang indicates her belief that we're unsaved. Probably because, in her mind, if we're elect God just hasn't zapped us yet. So she can say we're unregenerates now, despite our belief in the Gospel. If God chooses to zap us, then we'll be saved. She can't say it won't happen because no Calvinist can say who is and isn't elect or when God will zap those He elects to zap.
But PPS goes far beyond that. He believes that if one lacks the knowledge which, of everyone on TOL, only he possesses, one cannot be saved even if he/she has believed "the power of God unto salvation." He's already affirmed this several times about us all. That means he believes the Gospel is subsidiary to the "deeper knowledge" such as he possesses, which knowledge is real reason he is saved and we are not.
That's truly into the deep weeds of Jim Jones guru type cultism, on top of it also being a false gospel.
Excellent post. My compliments.
