If I remember correctly, the public talk given by Nathan Knorr at the 1958 International Convention in New York was entitled "God's Kingdom Rules - Is The World's End Near?" Probably a good idea that with this new release, the "Is The World's End Near?" part was dropped. Even though I was 7 years old, I can remember leaving invitations to this lecture in office buildings in Manhattan. I remember the feeling of urgency in getting as many of the invitations distributed as we could.
I find it interesting, to say the least, that 56 years later, the new release is retrospective in nature, as is the "100 Years of Christ's Rule" diversion. Funny how so long ago we were forward-looking. Today, it's all about distraction from the failed expectations.
