Searchinggal: They now are asking me for scriptures as to why they are wrong and I am correct.
Just because you can't prove them wrong doesn't mean they are right.
If you haven't already cut off contact with them, here's something you might try. Ask for one of their books -- doesn't really matter which one; they're all the same crap -- and tell them you'll read it and do some independent research on it, then get back to them with questions.
Check out some of the many very good websites (maybe someone here can supply a list) that debunk the WTS's doctrines. And, as an added plus, these sites will document specific instances of murder-by-proxy via the blood doctrine, child molestation cases, the WTS's former alliance with the UN (which they publicly renounce as an agency of Satan), and many other juicy tidbits your friend and her husband will find difficult to debate.
You'll have to set your feelings of friendship aside. Your "friend" and her husband are intent on bullying you into submission. Don't let them do it. No friendship is worth giving up your freedom to think for yourself.
