I Corinthians 4:11

Even unto this present hour we both hunger, and thirst, and are naked, and are buffeted, and have no certain dwellingplace (KJV)

Then: Here are five worldly life circumstances of the apostolic leaders. These differ considerably from the members of the church in Corinth. Fee (p. 178) talks about the chiastic order of the list, a literary set-up characterized by saying things forwards and backwards. In several upcoming verses, Paul goes from the end to the beginning of this list in discussing each one. That discussion also includes a sixth problem (menial labor) listed in the beginning of verse twelve.

Now: To concentrate on comparing prosperous Christians with impoverished ones is to go a little off track. Those who work hard and are blessed can do a lot to improve the life circumstances of the less fortunate. The point is not rich versus poor, but the willingness to sacrifice for the kingdom. The issue is better seen as a matter of pride and sense of superiority over other believers.
