Most none JWs will be killed at Armageddon. That means, 99% of the planet. It will be a blood bath.
This is a great point. In my last ever allowed public prayer instead of the time worn, "Jehovah, we pray for the time you bring the promised end to wicked people and we inherit the earth as you promised," I re-worded it to say the exact same thing. Of course I got called on the carpet for saying, "Jehovah, we pray for the time very soon now when you will kill nearly 8 billion men, women, and children so that only the very few who are baptized Jehovah's Witnesses are left alive on the earth."
Hey, it is what the former more popular request actually says.
