Been a while now since I was in, I seem to remember though that a lot of the plagues and prophesies of the Revelation where taught to have allready occurred.
I certainly remember and never quite believing, that the final and climatic verse of the book of Daniel, the most happyfying event that would occur at the end of the days, nothing better than this will ever happen to mankind was..............................the 1922 convention at Cedar Point Ohio.
Now the thing is, its more than just this "generation passing away" business, its the fact that when God released his people the Hebrews from captivity, led by Moses into the promised land, this was a pattern for an even greater fullfillment by the greater Moses at the end of the days.
Now those Eygptians suffered plagues that left them in no doubt whatsoever, what was happening, who God was, and who where his people.
The plagues didnt happen to one generation who where left thinking, "whats all this about then?" as fireballs fell from the sky, only to die and their grandchildren to recieve the answer to the question only thier dead Grandparents knew.
Like wise, if all these signs and wonders of Revelation have occurred, and the folk that witnesses them have died and gone, what was the purpose? who has learned anything?, what will it mean for the grandchildren of the 1914 generation who never experienced these "Biblical" events, when something does happen, unless God goes through the whole process again in order to remind mankind, they are likely to think we are being invaded by Aliens or some such.
I wonder how many Witnesses realise the happiest event in mankinds history occurred back in 1922 ?, never mind the Billions of others alive today.
When God does act, people are going to be aware of it, they will be in no doubt as to what is occurring, and it wont need a cloud of Pioneers with Revelation its Grand Climax books helping to explain whats going on!
