You need to understand two things
Any Christian sect that has there entirely theology all tied together by the book of revelations is really bad news. No one is completely sure what it all means.
The WTS has no concept of what the new testament is all about. Judaism to Christianity, the law of Moses to the law of grace, the nation of Israel to the body of Christ ( the church ), saves though works to being saved though faith.
Once you understand the big picture, it makes the WTS bamboozal just freakin stupid with the earth hopers and heavenly hopers and the faithful slavers that can only understand the bible.
