What makes Jehovahs Witnesses interpretation of the Bible truthful?
If you believe in relativism, that it can be true ‘for them’ but others can disagree, then it will be true within their limited framework of the theocratic Watchtower organisation in Brooklyn and of those who align themselves with this view. Such persons will quote the Bible at great length to confuse unwary souls, but like many other cults they re-define terms and also mis-translate the Biblical text to suit their own theology. This is only truth ‘for them’ it is not objectively so.
