In my contact with JWs during the 1990s, I got to thinking. "The WT says it's the Ark. Noah took 120 years to build the Ark. Add 120 to 1914 , and you get 2034. I never posted that thought to this or earlier boards (wasn't one called H2O, or some such? 🤔) because, to be quite frank, I didn't want to give the WT any ideas.
Thinking about it further now, 1919 is the true foundational date. That would have been when the WT was declared to be the Ark, typologically* speaking. So, WT gets a further reprieve, with their final date stretched to 2039, once you add the 120 years.
* Or is that antitypologically? I never understood that earlier JW stuff about types and antitypes. 🙄 Neither did the current GB, apparently; they've declared the whole concept null and void.
