The recent "generation" explanation redo says that the generation means the anointed living now, and we can still have more anointed, therefore there is no limit on how long the generation can run. This is an attempt to keep 1914 alive and healthy.
However, the WTS still teaches that the great crowd began to be gathered in the 1930's (ex: Rutherford had people stand and said "Behold, the great multitude) Since Revelation defines the great crowd as coming out of the great tribulation, doesn't that create a life span problem? What is going through the minds of even the youngest baptized 10 year old members of the great crowd in 1935 who are now in there 80's.
The Other sheep of John 10 seems to fit a discription of Gentiles. But, the WTS distinguishes Other sheep and great crowd with a slight difference. OS will live on earth, even if resurrected, but GC live through the great tribulation. So, maybe Rutherford should have said, "Behold.. a few of you little kids are part of the Great Multitude if you live well past your 80's"
My point is, why do they still teach that the GC began to be gathered in the 1930's. It's getting to the point were their life span doesn't fit the definition. They seem to be always occupied with how prophesy applies to the annointed, but the GC generation isn't working either. Instead of counting the remaining memorial partakers. Let's just count how many OS/GC were baptized in the 1930's, because the end has to come before they die. Right?
