From an early copy of the November 15 Watchtower -
12 In similar fashion to the invisible parousia of our Lord in 1914, this imminent destruction of false religion will likely be invisble also. Those with 'eyes of faith' will be able to see it occur. They will rejoice when the clergy begin to finally see that they are really a bunch of dead guys walking. Then these faithless ones of the earth will come clamoring to the doors of Jehovah's figurative [also invisible] ark for salvation. They will pound with invisble fists as the invisible destruction falls upon them and the invisble blood reaches the invisble bridles of the invisible prophetic horses spoken of by the now actually dead Ezekiel.
13 Then who will be the laughingstock, as we look about with our eyes of faith and see that we are the only people on earth that know that religion is gone and that all of mankind, who still believe they are alive, are really dead. Religion will have died an invisible death at the hands of the grand and Invisible Creator. What can we say now? We say again and again - 'Awesome' is your throne and your kingdom in all it's invisible glory.
