Wasn't there a Jehovah's Witness crewman on Star Trek: The Next Generation? In the 24th Century, Bible study time had been reduced to a week. If no progress was made, well, it was the person's own fault. By that time the end will really be near...as in really!
My old economics professor said if you keep predicting doom long enough, eventually you'll be right.
If, after all this time, the end comes, the JWs will say, "See, we told you!"
Why do they think God is taking so much time to draw everything to a close? Maybe it's an "invisible" end.... It's happened. We just can't see it. If it worked for the Catholics and transubstantiation and the return of Jesus in 1914 with the Witnesses, it might just work for the end.
