Rev 8:8
8 [e]When the second angel blew his trumpet, something like a large burning mountain was hurled into the sea. A third of the sea turned to blood, 9 a third of the creatures living in the sea[f] died, and a third of the ships were wrecked.
The mountain is a reference to Jerusalem, which was built on a mountain range. The sea is to represent the gentile nations (refer Daniel 7 where the Gentile powers are symbolized by the 4 beasts (the 4 kingdoms) which arise out of the sea (Dan 7:2-27)) or Psalm 65:7 where the “roaring of the Seas” is “the tumult of the peoples”.
This is also Jeremiah 51
“And I will make you a burnt out mountain... the sea has come up over Babylon; she has been engulfed with its tumultuous waters” — Jerusalem of pre-70 AD was the new Babylon
Josephus in his first century writing “Wars of the Jews” talks of how the legions set fire to teh city, causing Jerusalem to appear as “one blazing mountain” “Because this hill was hight, and the works at the temple were very great, one would have thought the whole city had been on fire... as full of fire on every part of it, that the blood was larger in quantity than the fire”
100% diversionary preterist gibberish.
I think the ‘sea’ is the roiling of people, not necessarily water. We see the great tumult in our own society right now and it’s only going to get worse. Just like in Sodom & Gomorrah where the sinful were so proud as to bang on the door to send out the men for sex, we are also in that place in society. And, like Lot, we are appeasing the wicked (take my daughter instead)...
