In the 90s I had a conversation with a girl who had been born in 1975. Her mother's sister (a JW) used to point at the mother's baby bump and say something like "That baby's never going to be born". Presumably meaning "Armageddon's imminent and you're going to die!"
Apparently it was the family joke from then on that that girl was "the baby who was never going to be born".
Rattigan, the JWs totally believed that stuff, and it wasn't people"running ahead of Jehovah "; they were being told this from platforms around the world (this happened in Australia).
Edited to clarify: She was probably due in 1976 (she was 18 in 1994), hence the "will never be born") thing, the pregnancy being during 1975.
