The friends here always go to the OT or the book of Revelation, because that's where they can use obscure passages to aim their prejudices, contempt and sanctimonious BS at others.
Much of what I posted originally I believe to be somewhat correct and I say this based on a good deal of research. Revelation is not a weapon for Christians to use to attack each other because it mostly speaks about how corrupt Christianity will become and how it will be replaced by a new song, or religion.
