Indeed. We are known by our fruit, so that doesn't speak well of some of them.
Is repeating your view that the Revelation 19 passage "proves" your case supposed to convince me? Why do you keep repeating yourself? If you can't convince someone of your argument the first time you say it, repeating the same argument won't convince them either. I've stated my case, and you've stated yours. If either you or someone else needs me to repeat my view on Revelation 19, I will. Otherwise, I believe you know my view, and I know you disagree. If you truly doubt if any other reader here (besides
@kyredneck, of course) believes the beast has come and gone, why waste so much time repeating your arguments when you don't need to convince anyone else? You arguments certainly will not convince any Preterist to change his view.
Yes, presenting the truth in all Scriptural matters is an important part of witnessing. When I witness to others, I focus on salvation and sanctification. Discussing different "end times" views is fine, but it can easily become a distraction. One's salvation does not depend on their eschatological view.
