even if there was a really vague kind of scripture that could say something along the lines of;
" Jesus said; truly I will say to you my brothers that in a time many years from now there will be a group of faithful servants, and I will see them in heaven and I will appoint this group as the master of my Earthly belongings, but they must not be promoting any untruths or lies, they must be teaching the most purest form of worship that can be linked to what we are doing now"
it would still rule out Russells Bible Students though, he'd probably be down the bottom of the list that JC would have undertaken on this so called inspection.
