The Work Of Deacons

I'm presently doing a series of lesson on deacons as we prepare to add more. What resources have you found helpful?

Here are some I am using.
First, the Bible. It has so much to say about service, leadership etc.

Second,
Deacons, Wake Up!: A First-Century Call for Today's Servants

Third,
The deacon and his work

Let me know of other great resources.
