So Scripture pictures an open revolt against God, and His authority, and ALL rule and authority on earth. This is one of the main subjects of the book of Revelation, but is probably first pictured clearly in Psalm 2.

“Why do the nations rage,
And the peoples plot a vain thing?”
Psa 2:1

So it is the “nations,” plural that are in an uproar, are raging against God and His commandments, and it is “peoples” plural that are plotting against God! Further it is also the kings and presidents and dictators of the earth taking a stand against God Almighty.

“2 The kings of the earth take a stand,
And the rulers take counsel together,
Against Yahweh, and against his anointed, saying, 3 “Let’s break their bonds apart,
And cast away their cords from us.””
Psa 2:2-3

They want their connections to Almighty God ended, their bonds to Him ended. Historically, such a wide open revolt against God has never happened! It is clearly pictured in the book of Revelation. This is, indeed, insanity in the extreme. Clearly they do not understand about God that,

“14 If he set his heart on himself,
If he gathered to himself his spirit and his breath;
15 All flesh would perish together,
And man would turn again to dust.”
Job 34:14-15

As we have seen, this world wide raging against God is also pictured in Psalm 46.

So how does an Almighty God respond
to this insanity?

“4 He who sits in the heavens will laugh.
The Lord will have them in derision.
5 Then he will speak to them in his anger,
And terrify them in his wrath:”
Psa 2:4-5

In Psalm 46 this is pictured as,

“He lifted his voice,
and the earth melted.” Psa 46:6c

That is a summary of those chapters 19 and 20 in the book of Revelation.

There were some preliminaries of course. Trumpets of warning included famine, sword and plagues turning the sea to blood, and more, Revelation chapters 6 to 8. Other things are listed in Revelation chapters 14 to 16. Remember always that Revelation is a series of parallel visions, with the final visions placing more emphasis on the end things. David speaks of some of these things in Psalm 65.

“Who stills the roaring of the seas,
The roaring of their waves,
And the turmoil of the nations.”
Psa 65:7

Jesus says,

“There will be signs in the sun, moon, and stars; and on the earth anxiety of nations, in perplexity for the roaring of the sea and the waves;”
Lk 21:25

These are signs of the end.

“But when these things begin to happen, look up, and lift up your heads, because your redemption is near.”
Lk 21:28

Then will come the earth melting

“… and the elements will be dissolved with fervent heat, and the earth and the works that are in it will be burned up.”
2Pe 3:10

But it will be alright for God’s chosen ones.

“Yahweh of Hosts is with us.
The God of Jacob is our refuge.”
Psa 46:7
