I remember a trusted elder in a few public talks would emphasise that the Christian Greek Scriptures were written only for the anointed ones with a heavenly hope, and the Hebrew Scriptures were written only for the Jews.
So other than containing principles and lessons he inferred that the whole Bible was not written for the earthly class but that was why they needed to align themselves with the F&DS to receive spiritual meat in due season.
Which I guess is why most of Christendom who read the Bible figure that they will be in heaven, whereas the average JW has been told repeatedly that they will not be going to heaven - so they just hope that there will be a place for them to live on the earth, otherwise they are screwed.
