12 And the
fortress [mibtsar] of the high fort [misgab]
of thy walls [chowmah] shall he bring down [shachach], lay low [shaphel], and
bring [naga`] to the ground ['erets], even to the dust [`aphar].
KJV-Interlinear
12 And the high fortifications of his walls he will bring down, lay
low, and cast to the ground, to the dust. ESV
And so Isaiah completes this chapter with the final statement that all of the mighty things of this world, all of the mighty thins of humanity, will be destroyed as though they never existed.
The mighty fort with high walls, is symbolic of all that man looks to, for his security, for the justification of his opinions or beliefs or philosophies.
Whether military power, or financial power or political power, or technology, or medical advancements, or in whatever it is that humanity places its trust, all things, will prove to be impotent and will fall without so much as a little struggle.
To bring to the ground is destruction, but to be lowered to the level of the dust, is total and unrecognizable obliteration.
The dust cannot be distinguished from other dust, and dust eventually blows away in the wind, never to be found again.
Just as over the course of history, kingdoms rise and fall, and yet no one learns from their errors.
So too, the lives of most people continue from year to year, from decade to decade, and no one learns the error of their ways, and therefore, in the Tribulation, when the final seven years of humanity is on the brink of annihilation, people will still not see the error of their ways.
That is how strong indifference and arrogance is, and how much influence that these attributes have over the mind and thoughts of humanity.
And so, Isaiah, continues one chapter after another, painting the picture of continued disinterest and continued indifference and continued arrogance, and continued disregard for Gods Word, even in the face of overwhelming disasters and even the disintegration of the human race, as people still do not see the light, so to speak.
Even today, that is the case.
There is so much opportunity for people to learn truth and to grow up in their spiritual lives, and yet they do not. And they do not learn because they prefer their own opinions to those of God.
To learn a subject, any subject, you have to be taught, you have to study, you have to experience life, all three of these things, in order to learn. And unfortunately far too many people skip the first two things and rely only on their experiences. And that is why they fail. Because experience without truth, becomes very subjective and that gives only a false sense of knowledge, and false knowledge at that.
And so, life will continue to spiral until God brings history to its inevitable change, and end.
The only question for you or anyone is, will you be a part of your own spiritual success, or will you be an active participant in the disintegration of humanity?
