Those of you who have lived in areas of geographical divide may immediately get the reference to “northsider.” Maybe the layout of your particular town or city required more of an East/West distinction. If this is foreign, think American history and the Civil War.
Certain perceptions come when we associate people with where they grew up. Maybe the more wealthily lived on the north side. There are far more Country Clubs on the north side of Oklahoma City than on the south side.
What thoughts would come to mind if you considered Jesus a northsider who visited a southside revival? Maybe that is one way to think about Mark 1:4-11.
