Here the prophecy of Isaiah turns to the nations:
24 The LORD Almighty has sworn,
“Surely, as I have planned, so it will be,
and as I have purposed, so it will stand.
25 I will crush the Assyrian in my land;
on my mountains I will trample him down.
His yoke will be taken from my people,
and his burden removed from their shoulders.”
26 This is the plan determined for the whole world;
this is the hand stretched out over all nations.
27 For the LORD Almighty has purposed, and who can thwart him?
His hand is stretched out, and who can turn it back?
For Isaiah and the remanent of Gods people it must have been reassuring that in the midst of large enemy nations exerting their military strength, the Lord was still at work bringing about his purposes.
In the midst of the greatest enemies we face; sin and death it reassuring to know, the Lord has worked out his purposes and who can turn it back.
38For I am convinced that neither death nor life, neither angels nor demons,[m] neither the present nor the future, nor any powers, 39neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord. Rom 8:38-39
