I believe that "ignorance" is a good reason to stay as a Witness. And I think that many JWs believe that IF they screw up , they're gonna get it later by Jehovah Himself. Sad, really.
Do You Realize That You Lived In Constant Fear as A Witness?
You were a lay preacher of the Bible and you had to carry the burden of responsibility not to do naughty things and profane this sacred work, in other religions it is the professional priests that carry out this function and they get rewarded for it, it's their full time job. To the contrary their flock is not burdened with such a task.
