Serving.... or not

I spent a fair amount of time last year in Philippians, and determined one of Paul's major themes was service. With our church's emphasis on service this summer, I'd like to keep Philippians current in my thinking. Right now I'm working on a study in Malachi. Last night I noticed it seems to have a theme of "how not to serve." I'll have to give that some more thought, and see if that concept is really there.
