But how can one argue with an original copy of a publication they printed at HQ?
But why would an active JW want to argue with you over the date 1925? They will simply dismiss it as old understanding.
Anyway, they have mentioned in their publications that they were wrong about 1925:
Watchtower 1993, 11/1, para 18-20:
Further, the widely circulated booklet Millions Now Living Will Never Die presented the view that in 1925, God’s purposes regarding the restoring of the earth to Paradise and the resurrecting of the faithful ones of old would begin to be fulfilled.
The year 1925 came to its conclusion, but the end was not yet! Ever since the 1870’s, Bible Students had been serving with a date in mind —first 1914, then 1925. Now, they realized that they must serve for as long as Jehovah wishes.
