Locutus, please let us know what your father and brother say, but I bet it will go something like:
"Our dedication to Jehovah is not for a limited amount of time or until some date."
First of all, that's not the point... the point is that some man made organization has claimed to be God's channel of truth in this "time of the end." All of their predictions and writings about the time of the end have proved false. Every single thing about "The Gentile Times" has been "refined" or "better understood" or retracted in some way.

Secondly... then why the HELL do they keep talking about DATES? They have not given up on 1914 as the year of something significant... a pivotal point for the "generation" but they obviously don't have a clue what it was. Now, they seem to just be pulling it out of their asses as they go.
