Balaamsass2,
Sounds a bit like the Dervishes in the Sudan. Their religious leader assured them that their "faith would render them bulletproof". However, though, if they did get themselves shot, it was all their own fault for "not having enough faith".
Similarly, the WTS/GB assures its adherents that as long as they "put Jehovah first" then all their material needs will be met. However, if they do experience material hardship, as your ex-wife did, then it is still their own fault for "not being more balanced."
In other words, if everything goes right then it is a case of "We told you that was going to happen"; but if it all goes wrong, then it is very much as case of "It's your own bloody fault".
Talk about expecting to have it both ways!
