I'm of the opinion that 60-70% know, or act like, it is not really the truth and the "the end" will not come in their lifetime yet it is a social environment that they are in that would destroy them if they left.
Thus, 60%-70% of each cong just does their bit...an hour here or an hour there...goes to a meeting etc...the rest maybe believe it more and are pioneers/elders and put a bit more urgency in but let us be honest...and I used to make this point in elder meetings when I was in...IF it is the truth why isn't everyone a pioneer and busting their guts? Surely a few years doing that to show almighty jehoover you love him is the best way to do so to get back everlasting life?
The fact many do not shows they don't really believe it to that extent. And therein comes the lack of urgency.
Honestly, how many in your old cong can answer, without reference, how they get to 1914 using the bible? Very few, they do not know their own doctrines well enough...it is a way of life, a social group...closed...that is the attraction rather than the religion itself.
