Hear All Peoples? (Micah 1:1-5)

The prophet Micah was sent to Israel with a message that was very relevant and urgent for the Northern and Southern Kingdoms in Canaan.  It is tempting to think that this is an in-house problem that impacts the immediate recipients of the letter excusing us from all responsibility.  However, Micah calls all peoples to listen.  All peoples are to hear the prophet speak.  Why should we care what happens to these people in this unique time?  What relevant message can the prophet bring to us today?
