Job 9:32-35 (NIV):
[God] is not a mere mortal like me that I might answer him, that we might confront each other in court. If only there were someone to mediate between us, someone to bring us together, 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.
My initial reaction to this was, “Just wait, Job; just wait. Your Mediator is coming” (1 Tim. 2:5).
Then I thought about what this suggests about God. The fact is, even under the Old Covenant, God calls humans to reason with him and come away washed white as snow! (Isa. 1:16-20). Later, when Job does get to confront God, without a mediator, yes, God frightens Job with terror, but concludes by justifying him. In chapter 42, Job—in terror—repents in dust and ashes (though he did not have to go get dust and ashes; he was already in the ashes.) God says no more to him, but rebukes his “comforters” and tells them Job has said what is right.
The point is that Job had audience with God without a mediator and came away justified. He got what God offers in Isaiah 1:16-19. Later, God used Job (along with Noah and Daniel) as an example of righteousness (Ezek. 14:14,20).
I am not saying that we do not need a Mediator. I run to that Mediator because I want to be among the saved who know the truth (1 Tim. 2:4-5). I have confident access to the throne of grace because of faith in the Mediator (Eph. 3:12; Heb. 4:16). When I am there, he is always at my side (1 Jn. 2:1-2).
What I am saying is that God’s character is often misrepresented. He is portrayed as unmerciful and harsh under the Old Covenant when, in fact, the Bible teaches from the beginning that he is merciful and kind, punishing only the guilty (Ex. 34:6-7). This is every bit as true under the New Covenant (Gal. 6:7-8). Even as Jeremiah mourned the just and forewarned destruction of Jerusalem, he announced, “The steadfast love of the Lord never ceases; his mercies never come to an end. They are new every morning; great is your faithfulness” (Lam. 3:22-23).
