Deliverance through Affliction?

I'm trying to figure out Elihu's role in Job, and the more I consider, the more I think he is a voice of truth speaking into Job's life, not in continuity with but in contrast to, Job's others three "friends." Elihu still, I think, retains some of the problematic assumptions of the other friends--such as in 36:8-9--but in light of 32:1-5 and the fact that he is omitted from God's rebuke at the end of the book, and that much of what he says does seem to provide a healthy corrective to what Job has listened to (and contributed himself) thus far, I do think he is generally a voice of truth, not folly.

Anyhow, I noticed the following verse today (from the mouth of Elihu), which, I think, encapsulates the core of the paradox driving Paul in 2 Corinthians. A lesson contrary to the mindset in ancient Corinth, modern America, and one I feel like an infant in.

He delivers the afflicted by their affliction and opens their ear by adversity. (36:15)

There is a deliverance in this fallen world that comes not by avoiding or overcoming affliction but by going through it.

The ultimate instance: Christ's cross.

When through fiery trials thy pathway shall lie,
My grace, all sufficient, shall be thy supply
The flame shall not hurt thee, I only design
Thy dross to consume and thy gold to refine
