You Lousy Witnesses! (Job 16-17)

The interactions between Job and the counselors has not been overly positive.  In fact, Job has been beaten up pretty badly in this process and their interactions have by and large bypassed each other.  One would hope that at some point the gospel would come out.  Unfortunately, Job continues to cling to his righteousness, but is he beginning to see that his righteousness is not enough?  Is Job finally starting to see that retreating into the pit of Sheol is not a refuge at all?
