So is antichrist destroyed by the brightness of Christ, or the lake of fire?
The word translated "destroyed" in 2Th2:8 is "G2673 - katargesei / katargeo - to annul [to render inoperative]" and is the same word used in Galatians 5:4 (translated there as "severed" in the blb, esv and others), "Whoever are being justified in the Law, you are severed [G2673] from Christ"... and isn't this the kind of thing we see in Revelation 19:20 and its parallel Isaiah 24:21-22[23]?
I mean, they do not enter the promised and prophesied earthly Millennial Kingdom (as do others / the saints / the righteous, at the time of His Second Coming to the earth [whereas the SECOND "PUNISH" word in the Isaiah passage correlates with the later GWTj context, that is, separated by the very specific "time period" shown to take place after the FIRST of TWO "PUNISH" words in that passage])
