How then can a man be righteous before God?

Job 25:1-6
Bildad replied:
Dominion and awe belong to God; he establishes oder in the heights of heaven.
How then can a man be righteous before God? How can one born of woman be pure?
How much less man, who is but a maggot蛆- a son of man who is only a worm!
If the speech is complete as it stands, Job's friends have exhausted their argument. They have nothing more to say.
Bildad merely reiterates the obvious truth that no one is 100 percent perfect in God's sight.
Why?
This does not help Job. What point is there in godly living if God's punishment falls equally on good and bad?
How?
God is the sovereignty Lord, No one is perfect before the Lord, What will be if God's punishment falls equally on good and bad? So do our best to preach gospel to who unknown God.
