Let's not go overboard here. The JWs do have correct doctrine.
I understand your position, Rattigan. Many (if not most) do not leave the organization because of doctrinal matters. But when you examine it all, you have to come to some certain conclusions. Is this God's organization? Are the GB the faithful slave spoken of in Matthew 24:45? If they aren't, who are they? Are they false prophets? What did they prophecy? Can they pass the test of a prophet given at Deut 18:20-22? If they are false prophets, what else could they be wrong on? If they are false prophets, should we not reexamine everything they've said to make sure of all things? (1Thess 5:21)
You see, this is a journey of reexamination. You may end up believing in a paradise earth, two classes of Christians, Jesus being Michael the archangel, God having a single organization, soul sleep, etc. Or...you may not. The fantastic thing is that you can reexamine these teachings and find out if they are really so, according to the Bible. No more fear.
More often than not, you may find that many of these doctrines are not correct. Some are based on the mistranslation of the NWT, which was "translated" by men that did not know Hebrew or Greek. Getting a different translation (almost ANY other translation is better) is vital. And be willing to follow truth. Don't approach it with the view "Well...most of the JW doctrines are correct." No, approach it with as little bias as you can muster. Don't worry if you find that many of these doctrines were false.
It's amazing what happens when you read the Bible by itself, and are not blasted with WT comments like "The false religious teaching of...." or "This is a pagan teaching..." So many things that JWs reject are very clearly taught in the Bible. I'm not going to comment further on that. I just want to encourage you to get into your bible deeply and reexamine everything.
