As Ted Peters once pointed out, in the English language, it's curious that the word evil is "live" spelled backwards. And indeed, evil always destroys. Life is diminished if not wiped out where the demons rule. The death of the pigs reflects that. What's more, in the Ancient Near East, the sea represented one of the forces of chaos that people feared. So it's a double-whammy: first there is death but second there is death by drowning in the sea, thus piling up and compounding the sense of chaos and evil in this story.

But the sad spectacle of those hapless pigs rushing headlong into the sea also reminds us that the expelling of evil from our world always involves sacrifice. For whatever the reason, God does not simply wave a magic wand to eliminate evil. Rooting out evil takes time, takes effort, and takes above all sacrifice. This should hardly come as any surprise, however, to people who live their lives in the shadow of a cross.

One final point, however: Jesus was chased away by the townsfolk but the healed man remained and according to verse 39, he kept on talking about what Jesus had done. Something about his ongoing witness reminds us that this is also our role: lots of people in this world try to chase Jesus away. Our task is to hang around anyway and to just keep talking, just keep witnessing to Jesus' work, and just keep hoping that at the end of the day, that witness will bring people back to the very Jesus they once chased away. "Return home and tell how much God has done for you," Jesus told this man.

He tells the rest of us the exact same thing.
