Evidently just about anything is possible when generations overlap.
By definition generations overlap. The puzzle is what did Jesus mean by generation when applying it to his parousia. We at JW have tried to apply every possible definition (given JC parousia began in 1914 and JW theology ) So if 1914 is correct Jesus words must come true. That is to say, the expected gt. It is overdue. It seems to be delaying.
