Wherever did we come up with that?

Isn't it obvious that God deliberately chose men and women that the culture overlooks and exploits and abuses, chose these 'nobodies' to expose the hollow pretensions of the 'somebodies'?...  ~  I Corinthains 1:28

"This is in constrast to the widespread and virutally unchallenged American strategy to target influencial and accomplished men and women for kingdom work - men and women, as we say, with 'proven leadership qualities' or at least 'leadership potential'.  Wherever did we come up with that?  Certainly not by reading the stories that Jesus told and the stories that were told about him." ~ Eugene Peterson, Tell it Slant: A Conversation on the Language of Jesus in His Stories and Prayers, p. 115
