I think that people should respect lurkers here, and not put them down so much. It is very difficult for them, no doubt, to come to this website and get some answers to their questions. It is easy to riducule someone in this forum, especially when some of you have suffered through so much, but it still does not make it really right. I know that JW's answers are somewhat silly at times, but I would have made the same comment if I was here and still part of the religion. (thank goodness I am not)
Anyways, I will answer your questions - the ones that I can answer.
Q1. JW's believe that they need god's holy spirit to understand scripture. They also need the help of "The Faithful + Descreet Slave", that being their visible organization. There is obviously tons of evidence to discount this theory!
Q2. No. They cannot question doctrines - they can have friendly "But I thought that it would be this way" kind of talks. If they do not understand something (like if something is unscriptual / makes no sense), they must "Trust In Jehovah". No, there is no reason for you to ever decide to leave the religion unless you disassosiate yourself.
Q3. They don't know what his name is - Jehovah or Yaweh. It could be something totally different! They recognize that fact and call him Jehovah because it is the name most used, in their opinion, in the past.
Q4. I have NO IDEA on that one.
Q5. What do you mean? CURRENTLY? They did teach in the 80's, early 90's, or hint to, that the 20th century would not be reached before armageddon. But, they said probably. Now who knows what they are thinking. It is supposed to be the generation who saw 1914, but it gets quite confusing there.
Q6. I have no idea on this one either. Would be interested to hear some answers from those who went through that.
Q7. I have no idea on that one, either! They have taught some pretty bizarre things in the past, so I would not put it past them.
Q8. No. They believed it was the start of God's kingdom in heaven - or so I think...
Q9. The answer is pretty blurry. They are supposedly following his guidance through the bible and through prayer on how to run things. You can make your own decision from there as to what it means... I don't know what you mean of the other question there - and thirdly, they believe that the truth keeps getting "brighter and brighter", and will change their minds on doctrines when they feel that doctrines are incorrect.
Q10. No idea.
Q11. No idea.
These are the doctrines as I remember them - they make a pretty convincing case at first, especially if you have no knowledge of the bible like I had. Eventually, you can see that scriptures do contradict each other in places, and you need to make your own judgement on those issues. Personally, I feel that they are wrong - as do most here, obviously. They use scripture to controll your every thought, and, if they are wrong, they just go "Whoops! We were wrong! sorry guys - if you were DF'd for a siin that is not really a sin anymore, you should have been faithful anyways.... utter nonsense. Any true christian would have stood up to different teachings like the Apostle Paul did, and like Job did.
