evangelist 1 ... I think you have already received some good answers. Part of your difficulty may stem from the fact that you are coming from a completely different paradigm than JWs. Understanding their core beliefs may be what you need to research next. Here is a link that may help with that: http://www.jwfacts.com/watchtower/core-watchtower-concepts.php
It takes time to fully understand all that is going on within the Jehovah's Witnesses. And your questions are going to lead to even more questions. Accepting that they are really a dangerous, high mind-control cult may actually help you to understand our answers more. If you are unfamiliar with mind-control tactics, check out this link: http://www.jwfacts.com/watchtower/fear-cult-mind-control.php
Most JWs don't know everything, either, about their so-called religion, especially the history and origins of the organization. Things constantly change too so there are continually shifting answers depending on which doctrines are under revision. I hope you're not getting dizzy yet. (I know I used to when I was a teenager studying with them).
Regarding editing your posts... you have about 30 minutes to re-edit one of your posts once you have submitted it. To do this, click on the pencil in the conversation bubble in the upper right hand corner of your post located right beside the date. Another tactic might be to wait for a few responses and then type up your responses and questions in a Notepad or Word type application, then copy and paste it into the Post a reply. This might help with your posting limit for now.
Simon is currently working on changing the site to enable profile updating. This is currently not available at this time. However, the site has recently been linked into 'Gravatar' and so, you can attempt to put your Globally Recognized Avatar up and link it back to this site by using the same email you used to sign up with here. I have tried to get it to work for me but have been unsuccessful so I have to wait for Simon's changes. At any rate, check out this link in order to set up your Gravatar: http://en.gravatar.com/
You can also use the Personal Message (called a 'PM') to ask certain posters more questions of a sensitive or personal nature. To do this click on the envelope in the upper right corner of the discussion board page, right next to your username.
don't they know the Jew were and still are God chosen people even though they are still blind to the truth?
No, they don't. The Jewish are no longer God's Chosen. Jehovah's Witnesses are. They were chosen in 1919 by Jesus Christ, who invisibly returned in 1914 to look around the Earth and select "God's Chosen Organization".
Does the JHW know that Jehavah God himself is grace just like He is love, so in a way if they don'z teach the love grace of God , they really are teaching about another God they don'z know but only heard some thing about Him!
No, JWs do not know that God himself is grace. Their view of Jehovah is that if they follow the Governing Body's instructions, they have a chance at passing judgment from Jehovah and Christ, and will gain eternal life. If they do not do as God's Chosen Organization's Governing Body (known as the Faithful and Discreet Slave) tells them to do, they will either not survive Armageddon or, if they die before Armageddon's arrival, they will not be resurrected.
Sorry for taking so long. I had a lot to type and lost most of it thanks to a mistake I made clicking myself away from the board and having to type this in all over again! Should take my own advice and use Notepad. Hope this helps. Talk to you soon.
