You might find it interesting to know that over the years, I've presented this simple challenge to JWs:
"Name just ONE doctrine that was unique to Russell and his Bible Students that is still taught by the WTS today."
No JW has been able to meet this challenge. They've mentioned things like "no hellfire, no trinity, the ransom sacrifice" and so forth but those beliefs which are still taught today are not unique to the JW religion.
Put simply, honest dubs would have to admit that for some strange reason God "chose" and God "directed" a "Laodecian Messenger" to preach and spread doctrine and chronology all of which has been discarded over the years.
To put it even more simply, if dubs are to be believed, then God is stupid with his selection of modern-day representatives.
