I have watched your video on Zephaniah. It wrongly says that Assyria and Babylon will do this punishment, whereas the prophecy says the Lord Himself will do it.
Also, you've got a real problem here because the Lord says he'll do it and then the prophets tend to say various nations will do it and back and forth it goes. The Lord IS doing it through Assyria, or Babylon, or Persia. It's like you don't think God is Sovereign, and that the prophets can't see God's hand in the actions of the nations. Or - it's like you have such a strong case of confirmation bias for your own vision that you just can't see any other possibilities. The Lord did it = Assyria did it or Babylon did it.
Yet if you bother going back and reading my post - you'll see not EVERYTHING in Zephaniah is fulfilled. Yet.
Zephaniah
Also, making 1:18 something to do with your Great Firey Day is just absurd. I mean, have you even read it? After describing war against Judah, Zephaniah is moved to describe the horror of the final Day of the Lord when all mankind is being judged. The Evangelical Commentary on the Bible - Walter A Lewell as editor explains that the following verse describes UNIVERSAL JUDGEMENT - the judgement of ALL mankind.
Neither their silver nor their gold
shall be able to deliver them
on the day of the wrath of the Lord.
In the fire of his jealousy,
all the earth shall be consumed;
for a
full and sudden end
he will make of all the inhabitants of the earth.
Tell me, who escapes this? Where's the escape clause again? Just point it out. Highlight it in red. Make it bold. Because I can't see it.
This is universal judgment. Where's the escape for the 'baddies' to go on doing bad things? Who survives to become your "One World Government" or the AOD or the precious Armageddon of the futurists? No one. This isn't some 'minor' catastrophe like a global nuclear war - with survivors. Zephaniah is describing nothing less than JUDGEMENT DAY as I have described it countless times. That's honestly the only way I can see it. There's no wiggle room, no watering this down, or inserting other verses over it. God's war against his own people brings Zephaniah's mind to the Final JUDGEMENT DAY. Fire, angels, Jesus, NHNE, eternal judgment, eternal salvation for those who believe.
This is theology, not timetable; universal judgment, not global solar catastrophe with pockets of 'baddies' to survive and be all 'baddie' another day!
