Well I HOPE he would warn people of the coming judgement which seems to be getting closer all the time! Bear in mind I was trying to say in my latter examples that we need that kind of a prophet, not that we will necessarily get them, outside of the two that we are going to get as described in Revelations. Yes, I know God could simply say "Look, it's all spelled out in the Bible, just read it already!" but it's also not like a lot of the prophets warning of the fall of Israel/Judah weren't also reiterating the curses spelled out by Moses. Also ... and I don't know why I just thought of it, but remember that there were certain things that John was told not to write of in revelations? Perhaps those things might be what a prophet would speak of?
I'm not sure what purpose this hypothetical prophet would serve though. I just know we are in sore need of one, someone to speak the Word of the Lord to us in a time when it seems the Devil is controlling this sad planet more and more. And I know that pretty much everyone out there calling themselves a prophet ... ain't. But like I also said, I can't rule out the idea that the Lord doesn't have someone out there somewhere speaking the Word of the Lord to people and places that desperately need it, as opposed to just playing cut-and-paste with the Bible and passing themselves off as a prophet or apostle.
Well, I still have't decided if I'm going for chicken or ribs yet.
