Psalm 82 "What do you want to do?"

Psalm for Today = 82:3-4

"Give justice to the weak and the fatherless;

maintain the right of the afflicted and the destitute.

Rescue the weak and the needy;

deliver them from the hand of the wicked.”

Comment: 
The words spoken by God in this psalm are to those who sit in judgment. 
These verses describe the God-ordained work of those in authority. 

Why is it that so often when people have some degree of authority and power they use it to advance themselves and to keep others down? Could there be better, more systemic, evidence for the Fall of man? I doubt it.

Do we use what authority and influence that we have been given to do what it is supposed to do?
