From the American Spectrum Encyclopedia (1991)
"Jehovah's Witnesses, ....Their central doctrine is that the Second Coming of Christ is imminent"
But it is a few men, some have already died, that say it is to them he has come. And they say that the Book of Revelation was written for the few men that Christ has come to. So they are supposedly the ones who "listen" as the Book tells us to listen and then they tell the world what Christ is telling.
So then anyone who believes that it is to the few men of the Watchtower that the good news is being directed might actually be hearing Christ but not listening because it is not coming from the self styled "God's Spirit directed organization".
In other words the Watchtower Organization says it is that which should be listened to. Everyone who believes them won't listen when Christ speaks because it's not coming from the Organization. It's coming from The Spirit.
That means the Jehovah's Witnesses are in the business of making people deaf. They are busy listening to the organization so they can't hear the spirit.
