But the Millenium is when we've gotten ridden most of the satanists (some are still in hiding during the millenium but cleaned out at the end for ever)

What OP is talking about is the end days as in the end of the satanic empire.

Israel is to be tested for 7 years with the entire planet attacking that place. Also they will be tested if they fall for the Antichrist and follow him.

Basically 7 years of refining.
