What Shall We DO?

In Luke 3, in the story of John's preaching and baptizing, we hear three times that different groups of people come and ask him, "What shall we do?"  And John gives such a "boring" answer.  He doesn't come up with a big ol' list of meritorious works.  He didn't suggest the things Tetzel advised.  He certainly doesn't come up with the kind of answers that tv preachers do.  He basically says, "Just keep doing your job.  But don't steal.  Don't lie.  Don't bully.  Oh, and if you have plenty, share with those who have nothing."  Nothing flashy.  Just do what God's given you to do, where He's put you.  And it won't earn you anything.  It's just what you do...
