These have certain qualities, yes, but mostly these are strong in faith. These lead in service. These men lead in service because they lead in love. They are sacrificially generous because they want the love of God to flow through them and their resources. Deacons in a church set a standard that few will surpass, and when someone does, they are made elders.
Deacons are leaders, designated servants, leaders in ministry.
If we should appoint men shepherds who are already pastoring, we should likewise ordain men as deacons who are already serving, ordain preachers who are already preaching, ordain evangelists who are already evangelizing, send missionaries abroad who are missionaries at home. The Bible says amazing little about deacons. But not all were deacons. We are going to select and reaffirm, ordain deacons. This is a time for prayer, for fasting, for meditation, contemplation, examination, testing.
