This chart is very accurate. I know this, since I use to be a JW for about 25 years. I did missionary work (pioneered) and went door to door and the whole bit. I got out of the "truth" when I asked an elder ANOTHER question, and he told me to stop asking questions and to believe the Watchtower. If he would have said the Bible, I might have listened. But that answer propelled me out of the JWs. It took me 12 years to even step into a church (since we were told churches were demonic). The Lord was faithful. He knew I really wanted to know Him. As a matter of fact, I firmly believe that He put that desire in me. I finally met Him, and now have a personal relationship with Him.
I would encourage anyone who is interested in JWs, to read this chart, especially the part about the New World Translation. The man who "translated" the Bible had about 2 years of university Greek. And with that he translated the Word of God! What huberis.
