why bad thing happen Job 40:1-14

The Lord said to Job:

2 “Will the one who contends with the Almighty correct him?
    Let him who accuses God answer him!”

3 Then Job answered the Lord:

4 “I am unworthy—how can I reply to you?
    I put my hand over my mouth.
5 I spoke once, but I have no answer—
    twice, but I will say no more.”

6 Then the Lord spoke to Job out of the storm:

7 “Brace yourself like a man;
    I will question you,
    and you shall answer me.

8 “Would you discredit my justice?
    Would you condemn me to justify yourself?
9 Do you have an arm like God’s,
    and can your voice thunder like his?
10 Then adorn yourself with glory and splendor,
    and clothe yourself in honor and majesty.
11 Unleash the fury of your wrath,
    look at all who are proud and bring them low,
12 look at all who are proud and humble them,
    crush the wicked where they stand.
13 Bury them all in the dust together;
    shroud their faces in the grave.
14 Then I myself will admit to you
    that your own right hand can save you.
