It sounds to me like the same thing that went on with the "Millions Now Living Will Never Die "
being changed to "Millions Now living May Never Die "
and also the year 1914 being when the end would come and all the brothers being taken up to heaven ?
And when that didn`t happen it changed to 1914 when we were in the time of the end and being taken up to heaven was for a future date ,and in the meantime we have to Preach This Good News of The Kingdom for a Witness to all the Nations and the End will come ,which still has not been accomplished.
The preaching of this good news of the kingdom to all of the nations.Nowhere near ever being fulfilled .
Mainland China ? No
Muslim Countries ? No
And that alone means Billions of people who have never heard of Jehovah God or any of his witnesses.And not even heard of the Christian Bible.
