CLAIM: Jesus will rule all the nations from Jerusalem in the Millennial Kingdom.
True.
Speaks of the law going forth from Jerusalem. It would not be the Millennium, as proposed, but it is a future event, most likely after the Gog Magog of Ezekiel 38 & 39 in the interim, wherein seven years are spent simply burning the weapons of war for fuel. There is no indication in Revelation 20 that the Second Coming follows directly on the tail of the Gog Magog conflict. It merely lists the sequence of events, but there could be any length of time at all between the two occurances, as in the previous chapters of Revelatoin, roughly a hundred years were between subsequent passages.
