I see that you didn't see fit to answer any question that I asked you. I said nothing about the world being in chaos (although it is). And yes, God's plan for salvation was carried out.
Job was blameless in the sight of God and the point that is being made is that even righteous people suffer - which was totally against what Job's "miserable comforters" thought. They (Job's miserable comforters) believed God protected the righteous and only allowed the unrighterous to suffer, and had concluded that Job was unrighteous. They said that Job had many sins (11, 15:5, 22:5 and 34:37 [NASB]), and that his children had sinned, which is why they were killed (8:4). God is not a bored puppeteer who gets his kicks by tormenting one of his puppets and killing a lot of innocent bystanders just to win a bet with the Devil . . if the devil actually has to get God's permission to do evil then evil would be easy to stop for God could just say NO. If Satan has to truly ask for permission, where are examples of this in the NT? There is a lesson to learn from the book of Job and it is not that Satan has to ask permission to be allowed to do anything . . . it shows that Job did not love God only because of what God had done for him but loved Him because He is God, worthy of love no matter what the circumstances were in his life - In all this, Job did not sin by charging God with wrongdoing." If Satan had to ask God's permission before doing evil then the so-called "war" between the forces of good and evil would be a sham.
Simple bottom line - God's people suffer great trials and tribulations . . . the devil is the god of this world (2 Cor. 4:4) and the world is under his control. (1 John 5:19)
