Job 9:32-35 (NIV)
"He is not a man like me that I might answer him, that we might confront each other in court. If only there were someone to arbitrate between us, to lay his hand upon us both, someone to remove God's rod from me, so that his terror would frighten me no more. Then I would speak up without fear of him, but as it now stands with me, I cannot.
Job looks at his situation and feels he needs someone to speak for him to God. This is a fascinating insight on Job's part. God is not like us, He is too holy, too awesome. In our frail humanness, we could not exist in his presence. So Job longs for someone who could speak for both God and man, someone who could touch both God and man. He hopes for someone who could remove God's wrath from him.
Who is it that could do such a job? He would have to be as pure as God to be able to approach Him and understand Him. He would have to be like a man to know his pain and plight. He would have hold the key to satisfy God's wrath. Friend, if you do not know such a person, let me introduce you to Jesus Christ, the God-man who not only can speak for us but who suffered and died in our place.
1 Timothy 2:5 (NIV)
For there is one God and one mediator between God and men, the man Christ Jesus,
