I believe the reason more JW's are partaking ( the number goes up about 1,000 each year the last 10-12 years or so ) so now what is there ? About 16,000 worldwide ?
The real reason is the WT Society about 10 - 12 years ago changed their teaching which once was that the door had been closed to more anointed being collected by 1935 . They used to teach the number had been sealed, " finished " , " done " by then . They opened it back up in about 2005 or so when they started getting younger and younger GB members who would need to be considered " anointed " in order to be GB members. So it was a convenient way to claim they had " new light " that God Jehober had opened up to receiving more anointed- when in reality it was " new light " for the convenience of getting these younger GB members stamped as " anointed " - so no one would question anything.
But the truth is- as many of you state here- by opening it back up- it invited every Tom, Dick, Harry , and crazy person to claim that THEY too are anointed. But as we know WT Society leaders are very adept at shooting themselves in their own foot. Not much thought goes into this alleged " new light " - other than " how can it benefit the WT GB and WT leaders to keep the organization afloat " . My 2 cents
