DT, good question. Only time will tell what the Organization does. Many individuals, like me, will face the hardship of thinking for themselves. Jehovah's Witnesses used to make sense, give hope, structure, and a measure of joy. Now, the 'present truth' is getting harder to swallow. And with all the restrictions, rules, regulations, plus demands of time, energy, and money, the future doesn't seem too bright when the present is so lacking.
My Struggle, the typical response you'd get from all the JWs I've known is, firstly, "We Jehovah's Witnesses are preaching all over the planet, who are you to try to preach to us. You got the gospel and you're going to preach to me? Knock on every door of this city to find me!" Next, it doesn't matter "gospel of the kingdom" or "good news of the kingdom", the JW perspective is "We serve the Kingdom. You only think you know what the kingdom is." It's easy enough for a JW to smell when someone's trying to preach-back and they'll put up the defenses. Maybe you'd get some to listen, but I wouldn't have. A simple approach for most JWs would be to listen politely, but say how happy you are with your church, Bible studies, the good friends, the activities for youths, programs for relief work, missions to other countries, etc. Simply showing that you're a really good person with a close happy family, that God wouldn't destroy, makes it less likely they'll dislike you and your religion. If they try to press the JW line, just let them know that you're aware of their confusion over doomsday prophecies based on Jesus' reference to a 'generation'. If they aren't backing away, tell them you're aware of the JW pedophile lawsuits and payoffs. Chances are, doctrinal disputes won't influence a JW, problems within the congregation are more likely to affect them.
That's my 2 cents... plus
