What are we doing?

I gave a presentation at a Parish meeting this evening.  The devotional was delivered by a pastor who also serves as a teacher during the day.  He asked his congregation to grade themselves in various areas of ministry.  Each person was to grade himself/herself in each area of ministry and then grade the church as a whole.

One thing that surpirsed him was that most of them graded themselves indiviudally lower than they graded the church as a whole.  What does that indicate?  Do we think other people do a better job than we do?  Do we think other people will do ministry we are unwilling to do?  Do we use the phrase "someone else will do it" as an excuse?  Or do we just not appreciate the nature and scope of the work that we do?
