During the 1973 convention, I well remember an elderly brother addressing the excited throngs (Ah! Those were the days when JWs actually lapped up every word uttered from the platform): He said something like:
"We ought not be fooled into thinking that the door to life will always remain open whilst this system of things continues. There will come a time when people will beg to study with us, but it will be too late...the preaching work will have then been completed".
We were told to get busy distributing the Kingdom News pamphlet before it was too late!!
This created such excitement in the on-edge crowd and we began breathlessly expressing among ourselves the need to step up our own preaching work because it would soon be stopping altogether.
Meanwhile, a quarter of a century later.....Nothing's changed.
