Just read Doubting Bro's post, which prompted me to re-read the account in Matt. 25:31-46 about the sheep and goats. I never noticed that, as Doubting Bro pointed out, verse 32 clearly discusses separating all the nations into either right-side (good) or left-side (bad). Then, in verse 34, the king says to those on his right that they would inherit the kingdom. Pretty standard stuff, right?
But where do the JW "earthly-hope" class fit into this? It looks like there are two classes here: (1) the sheep, who "inherit the kingdom"; and (2) the goats, who get killed. I don't see anything about a third class that is superior or inferior to the sheep class. And doesn't "inheriting the kingdom" mean that they go to heaven and rule? If someone told me that I was inheriting the kingdom of England, I would understand that to mean that I was going to be king--not that I was going to be one of 50 million or so subjects of the Crown.
I'm sure the WTS has some kind of tortured explanation for this, but I can see how you can read this parable and come away thinking that all good people go to heaven.
