OK I was told by witnesses since 1969 that they just "know" that they are being called for Heaven, rather than the earthly hope of other witnesses (great flock). Most are NOT virgins (like revelation says the 144,000 are.) Most are married. They don't have much on an input in materials that come out of Bethel. If they write an article, it is edited to match Watchtower specs. People I know who have known them personally, say they "just know" at some point in there JW career, that they are going to heaven. I once knew a guy they started to partake in the emblems and claimed he was one of the annointed. I thought it was weird, he was new to the group and had a nasty rep. He left the
JW quite soon afterward.
