Vidiot, Glad you asked LOL
Watchtower has weeded out some of that possibility by having those with "bad desires" including "bad JWs" killed off at Armageddon. Those who are resurrected or born after the big A or anyone else who develop "bad desires" are taught the "ways of Jehovah" and are given time to change. Those who want to, then magically only have "good" desires. Those who don't are killed poof, no need to wait till the final test after the 1,000 years.
Where does it say this in the Bible? Glad you asked. It doesn't. This information is available in a more reliable source- the Watchtower. I read all of the above info there so it HAS to be right. Unless, of course, there is NU LITe.
