Be careful that you are not falling for the old "confirmation bias" scenario where a person looks for "reasons" to shore up their current beleifs. It makes them "feel good" when they see or read something that "goes along" with what they believe. It gives them the "Yes! I made a good decision, I AM smart!" feeling.
If you like to "believe" things based on "how it makes you feel" rather than "if there's evidence" then please continue "actively searching" for reasons that the WTBTS MUST be god chosen religion. But if you want to see the other side as to why the WTBTS was not chosen by JC and GOD in 1918-1919 then read Don Camerons book entitled "Captives of a Concept"
Gloria Steinham once said "The truth will set you free, but first it's gonna piss you off!"
This will apply here also.
