I've marveled at Job's faith in Chapter 19, when in the midst of his pain he suddenly confesses hope: "I know that my redeemer lives, and that in the end he will stand on the earth. And after my skin has been destroyed, yet in my flesh I will see God." (Job 19:25-26)
I've just noticed he had a similar moment of hope in chapter 16:
"Even now my witness is in heaven;
my advocate is on high.
My intercessor is my friend
as my eyes pour out tears to God;
on behalf of a man he pleads with God
as one pleads for a friend." Job 16:19-21.
Job sees even in his suffering that God is more than the righteous judge, but also the one who takes our side, who seeks to be merciful. We can have faith in life's perplexing moments that God, our advocate and intercessor pleads for us.
