What evidence do you have that JWs belong to a dying religion?
First, I don't have evidence you are asking for, but some observations about Jehovah's Witnesses
Lets say the views, the interpretation of god, etc, by Jehovah's Witnesses are spot on. You all have gotten it. IMO, it seems that your delivery system is the problem. Over time your branch of Christianity has gotten a bad reputation, like someone's crazy uncle in the living room, where, I guess Jehovah's Witnesses many times end up. Although I think this reputation probably helps your "us vs. the world" mentality, that would fit nicely with interpretation of Jesus teaching. And Jesus said, roughly, "it is easier for a camel to pass through the eye of a needle than for a rich man to get to the kingdom of god. " I would say that visiting middle class homes throughout the world, Jehovah's Witness are "helping " people that Jesus would not have been most worried about. I interpret the teachings attributed to Jesus as being most worried about people that are rejected by society - prostitutes, tax collectors for Rome, lepers, people with disabilities, people with demons (the mentally ill) etc.
Although it can be very tough to knock on someone's door on a Sunday afternoon and get rejected, I believe Jehovah's Witnesses, having discovered THE truth, should ramp it up a notch. How common is it for Jehovah's Witnesses to visit prisons? Doing an internet search, it seems sometimes bible studies are set up, but I could not find much more. I think waiting for released prisoner's to offer transport, helping them get to support, find a job, get groceries, etc. could be much more fruitful, albeit dangerous, than meeting with middle class people in their living rooms. The problem with prison's is the location - usually not in the nicest areas, and usually far from everything (everyone's favorite NIMBY syndrome). I think of the Philadelphia prison system, along the swamps beside the Delaware River. Not a nice place - dangerous at 11:00 at night when the system may willy-nilly release a man or woman.
I wouldn't offer tracts to folks released, saying "Jesus is the way, the truth, the light" - they need shoes! And the more times someone goes through the prison system, it seems the more they will lose any support system. Offering them $50 could go a long way. I wouldn't mention Jehovah's Witnesses, or the Kingdom, I would just say you are a friend that they can turn to for support. If you think you must, give them a card with a phone number with some name, like "Jobs Church," where they could interpret the name to mean Job from the bible or a job. (hmmm, maybe Republicans donate money to this cause) Deeds may get you further than words. Now - would working like this as an individual get you in trouble with Jehovah's Witness leaders? If it would, why?
I think of 2 great religious leaders in the last 100 years. Martin Luther King Jr., and Ghandi - both men killed because, IMO, they were more than society could handle. You have a tough job ahead. Next some thoughts on how Jehovah's Witnesses can stop ISIS, maybe changing the way your version of the truth is viewed by the world. Thinking ahead, do you believe Obama's saying, " we will wipe out, destroy ISIS", is the quickest way to get Islamic Extremists to calm down?
