Job answers Bildad: Truly I know that it is so, but how can man be just with God? He does not deny God's justice, but he sees the problem from the other side. If he is pleased to contend with him, he can't answer him one time in a thousand. God is wise in heart, and mighty in strength. Who has hardened himself against him and prospered?
Job's praise of God's power is magnificent. He removes the mountains and shakes the earth out of its place. He commands the sun and it doesn't rise, and seals up the stars. He alone stretches out the heavens, and treads on the waves of the sea. He makes the Bear, Orion, and the Pleiades. He does great things past finding out. Yet Job cannot see Him: he goes by me, and I don't see him.
This power overwhelms Job. Even if he were righteous, his own mouth would condemn him. In despair he says God destroys the blameless and the wicked alike, words he will later regret in chapter 42. Then he voices a profound longing: For he is not a man, as I am, that I should answer him. There is no umpire between us, that might lay his hand on us both. In the New Testament, 1 Timothy 2:5 says there is one God and one mediator between God and men, the man Christ Jesus. Job's longing points forward to the Mediator God would provide.
