When is Isaiah 32 supposed to happen?

I'm reading Matt Perman's book [What's Best Next](http://www.amazon.com/Whats-Best-Next-Gospel-Transforms-ebook/dp/B006FP4PVY/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1394128758&sr=1-1&keywords=perman+what%27s+best+next) and found this interesting: >5. Knowing how to get things done enables us to fulfill God’s call to make plans for the good of others. This is one of the most exciting reasons to me. The biblical call on our lives is not to do good randomly and haphazardly. Rather, God calls us to be proactive in doing good — even to the point of making plans for the good of others. For example, Isaiah 32: 8 says that “he who is noble plans noble things, and on noble things he stands.” We often think of doing good simply as something we are to do when it crosses our path. But Isaiah shows us that we are also to take initiative to conceive, plan, and then execute endeavors for the good of others and the world. (And this requires, of course, actually knowing how to plan and actually make our plans happen!) >Perman, Matthew Aaron (2014-03-04).

In reading through Isaiah 32, there seems to be a kingdom of righteousness being described that sounds really good - but then it is almost immediately followed by a warning of destruction. Not really knowing Isaiah as well as I should, I'm trying to understand the context from which Perman is making this leap. Is this inference from Perman (that we should be actively planning noble things) directly drawn from the prophetic nature of what Isaiah is preaching here, or is there an eisegesis that is required to make the point?
