Saethydd, thank you for your measured analysis. The matter in hand is the role and inspiration of Watchtower governance. Here it is typically presented to the faithful in terms which ambivalently provide one argument for the faithful and another one for outsiders.
For the critics a new apologia or defence was needed to explain away the laughable inability of the WT to get dates right as well as their need for doctrinal flip-flops. The new stratagem is that “they are not inspired” yet at the same time their modesty is cast to the wind when they claim that they are exclusively appointed by God, enabling only them among all religions to have correct insights from 1919 onwards.
To an outsider this is unprovable and irrelevant but for JWs it attempts to get them off the hook for their succession of errors and reassure believers that they are stuck with the right bunch of Bible bashers.
This weasel talk in the Watchtower is the bread and butter for JWs, it has absolutely nothing to do with truth, it is purely of the nature of propaganda. For example the WT article you quote from uses the favourite GB expression “God’s people” so frequently, that it acts like a riveter’s hammer. If repeated enough: it must be a reality?
Watchtower material has two functions, primarily to condition the membership to continue uncritically believing that the GB are from God even if they publicly say they are not inspired, and secondly it remains by virtue of its repetition; the mechanism they use for reinforcement and loyalty to the organisation.
The purpose of propaganda is to enslave minds and hearts.
Who is leading? It is not any creator God or even a Canaanite idol called Yahweh. It’s not a “who”, it’s a “what” is leading? I suggest that it is nothing more mysterious than a commercial business drive which leads the JW organisation.
