The Great Crowd of Other Sheep Witnesses allegedly first began forming early on in the 20th century. Rutherford was totally unaware of this crowds existence until 1935. It was revealed to him in 1932 that the Great Crowd members were heaven-bound. Then light flashed from heaven in 1935 showing that this group was an earthly class. At a convention in Washington DC in 1935 he pointed to his cheering audience when he proclaimed, "Behold the Great Crowd".
"Jehovah's Witnesses themselves set the conditions through with the doctrine would stand or fall.
To wit:
"Especially beginning in 1935, when the identity of the "great multitude" or "great crowd" was clearly understood, large numbers of these began to manifest themselves. At first there were hundreds, then thousands, later hundreds of thousands, and now there are millions spread around the Globe. Gods infallible Word depicts this group as 'coming out of the great tribulation,' being survivors of it, living right on into God's New Order without ever having to die (Revelation 7:9,10,14; John 11:26) The early members of this group are now in their 60's or 70's or older. Jehovah did not allow the ingathering of this group to begin too soon. The "great crowd" including many of the earliest members thereof, will survive into the "new earth." (Survival Into a New Earth p. 185 )
Let's say generously that the average age of those conventioneers was 25...and the youngest was 15. The youngest person in that crowd would be 100 years old today. I doubt many of those earliest members are alive today. I wonder if any are.
Another prediction down the tube.
