This all comes together by instilling the notion that their interpretation of the bible is the correct and accurate one. Add in the notion of following us you'll be more righteous in the eyes of god , thereby offering a better chance of survival at the soon to come Armageddon.
Yes.
Although many beliefs teach, "We are right and others are wrong," Watchtower literature has really gone to the extreme of taking scripture snippets to seem to prove their doctrine is right and JW's have a better understandibg than anyone else.
The average JW is mainly only interested in being right about holidays or military service ir blood or whatever, and showing up anyone in disagreement.
It now seems to me that they do this so that when they want to push their agenda with no real scriptural backing, members are so accustomed to them providing elaborate proofs and they stop checking those reference scriptures. So they just tack on those "obey the slave" or "light-brighter" references and it is accepted.
