I find this very interesting, as it really shows one thing: Job in his misery is blinded by his circumstance of seeing God's glory. Yes, he did not sin and all, but did he do to his best? We do not know, but he certainly did better than most. 

Look at the word blustering, it means talk in a loud, aggressive, or indignant way with little effect. Job talked like this and He is considered to be
blustering. I honestly thought that whatever he said was very mild. Indeed we do not treat God with as much respect as the people in the past to. From here, i learn one thing- that we must treat God with utmost respect, even if it is just talking to Him or about Him.

This friend encourages him that God will restore glory to Job. More than that, people then value wisdom, seen from the discussion of former generation. Today's generation have no wisdom, all we have is knowledge. What good does it do? It drives us away from God. people then seek earnestly for the truth, for the wisdom in God.

8 Then Bildad the Shuhite replied:

² “How long will you say such things?
    Your words are a blustering wind.
³ Does God pervert justice?
    Does the Almighty pervert what is right?
⁴ When your children sinned against him,
    he gave them over to the penalty of their sin.
⁵ But if you will seek God earnestly
    and plead with the Almighty,
⁶ if you are pure and upright,
    even now he will rouse himself on your behalf
    and restore you to your prosperous state.
⁷ Your beginnings will seem humble,
    so prosperous will your future be.

⁸ “Ask the former generation
    and find out what their ancestors learned,
⁹ for we were born only yesterday and know nothing,
    and our days on earth are but a shadow.
¹⁰ Will they not instruct you and tell you?
    Will they not bring forth words from their understanding?
