Keller's Every Good Endeavor - Chapter 5 - Work Becomes Fruitless

I'll be facilitating a discussion on chapter five (pages 83-97) of Keller's work Monday evening. Here are some questions I've pulled together for discussion.

1. Keller begins with a look of Genesis 3 and the impact of sin (under the subhead "Things Fall Apart"). Share some specific, recent examples from work about how things fall apart.
    
2. On page 95, Keller begins to sum up the chapter with this: "That is why so many people inhabit the extremes of idealism and cynicism -- or even ricochet back and forth between those poles." Do you sense the same extremes in those around you? Do you occupy one of those poles? Or ricochet between those poles?
    
3. How do we respond when work appears to be fruitless?
