from what i've read and been taught, Magog is almost universally accepted to represent Russia (at the least, the land north of the Black & Caspian seas), not the USA. all the other lands involved in the war described in Ezekiel 38 are present-day Arab countries; Saudi, Libya, Egypt, Iran (Persia), Lebanon, etc.
if you're trying to tell me that one of these is actually the USA i'm not seeing it; maybe you're not being clear.
the rest of what i posted yesterday; i was responding to the link in the facebook post you linked to -- which is about linking Proverbs 9:1 to seven continents of the world -- i totally reject that.
there are not seven continents. there are 6 major land masses on the globe, 8 tectonic plates, and more like 10-12 major socio-political areas in the world. the saying that there are 7 is a complete fabrication just for the sake of using the fancy number 7.
the other bit from the article - "dr. so-and-so has proved Havilah is the USA" - is simply heresay. you quoted it from an article that also just quotes it, and doesn't give a source from dr. so-and-so --- that is to say, if it's proven, it's not been shown to me; all that's been shown is that dr. so-and-so says so, and we haven't actually heard from dr. so-and-so, so i'm not going to just repeat or accept it as fact.
it also remains to be shown how the USA being Havilah has anything to do with the USA being in biblical prophecy. in Genesis, 1 Samuel and 1 Chronicles, Havilah is mentioned as an area where Amalekites lived. did the ancient Hebrews fight American Indians in the Pacific Northwest, and call them Amalekites? i don't think so. so that's probably a flawed premise too.
i hope that makes it more clear.
now i'm not really well studied or knowledgeable about this, i grant you, but i'm not taking it all as gospel just because anyone says so. if you have something to teach us about this, please post it here on the forum, not just give links to your facebook posts, because like i said, most of the people here will not click links and go read all your activity on your social media pages. put the info here so everyone can see. thanks!
