Job 9:1-2 (KJV)
Then Job answered and said,
I know it is so of a truth: but how should man be just with God?

Job’s question is worthy of much reflection. The answer leads to genuine conversion and eternal salvation. We can be just with God only through the sacrifice God provided Himself. Faith alone in that sacrifice makes one just with God.

I would rather reflect, in this piece, on his affirmation of the discourse of Bildad. Some scholars even suggest it is an affirmation of what both Eliphaz and Bildad said. What these friends had spoken was not in error. Job agrees with them and further expounds upon their meditations. It seems to me that the problem is not with the truth of their words but:
Their purpose behind them
They wanted Job to admit some sin he had not committed but they were sure he must have done.

Their attitude in presenting them
They wanted to see Job humiliated. He had been one of the most powerful if not the most powerful man of his day. It is common for others to attack men like that if they are able.

Their conclusions after them
These men never resolve the subject. They represent truth about the holiness and justice of God and the sinful condition of man but they leave it there. The problem with that is that it leaves the impression that justice with God is earned by human work. That is simply not the case.

A man is made just with God by grace through faith or he is not made just with God at all.
