If your friend were suffering greatly (as Job was) it would make sense to point out that friend's strengths. But, Job was in no shape to hear this from his friend Eliphaz. (Who by the way, gave him rotten counsel overall.) But when I was suffering greatly with pain, it turned out my integrity WAS my hope. I am forever grateful to God for it.

Job 4:3-6
Surely you have instructed many,

And you have strengthened weak hands.
Your words have upheld him who was stumbling,
And you have strengthened the feeble knees;
But now it comes upon you, and you are weary;
It touches you, and you are troubled.
Is not your reverence your confidence?
And the integrity of your ways your hope?
