This is either the most selfish psalm in the world (if you only read verse 1) or

This is the most UNSELFISH psalm in the world (if you read the other 6 verses).

It asks that the Lord shine His face on US.  So is it just for those who know Him, for those that are already in His family? Or, is it ultimately that the whole world would know Him?! 

This is the most UNSELFISH psalm in the world because it is FOR THE WORLD.
