One of the goofiest speculations I heard was that JW's who live in "paradise" will no longer have any pets.
The reason? Animals are not perfect and do not have the hope of living forever. They will die. If pets were allowed people would get attached to them just as they do now, and when the pet died they would feel sad, and perhaps even shed tears. As Revelation 21: 4 says God will wipe out every tear from their eyes. . . neither will mourning be anymore. So the loss of a pet would cause something that God would not allow, so there would not be pets in "paradise".
Another almost as goofy was that if a person were chopping wood, and the axe slipped and buried itself in their leg they would not feel any pain from the injury. Used the same scripture in Revelation to prove that point.
You just cannot make this s--t up!
