Well it is interesting that the ORG has recorded about 22,000 as being partakers at the Memorial and Revelation tells us there will be 7,000 sealed, which is roughly 1/3rd of 22,000 if you accept that not all claiming to be anointed actually are.
Zechariah 13:8-9: “And in all the land,” declares Jehovah,“Two parts in it will be cut off and perish; And the third part will be left remaining in it. And I will bring the third part through the fire; And I will refine them as silver is refined, And test them as gold is tested. They will call on my name, And I will answer them.I will say, ‘They are my people,’ And they will say, ‘Jehovah is our God.’”
