The main work of the whole church for the whole age is evangeltheysm. The church is content oriented and the Bible is its source of authority.
Deacons have the opportunity and influence to help the entire church family stay on message.
Sometimes, we pastors are going to mess up. Sometimes, we will have to hear bad news. When this is true, we would rather hear it from my friends than from our enemies. Our friends want us to succeed. They will tell us in love, without trying to embarrass us or wound us.
