Can christians here explain Mark 5:2-13?

[Chad32]

I find it hard to read that sermon, since the guy is talking about stuff that doesn't really have to do with the story. He seems to think there weren't really demons, and it was all just the guy. I would want a more straightforward explanation. Obviously he thinks this story is a metaphor, instead of literal.

Edit: Actually it doesn't say Jesus paid anyone back for the pigs, or apologized. They just told him to leave, presumably because he just cost them a herd of pigs.

To be honest, the book was written by people who worshiped Jesus, and probably wouldn't care about what happened to the pigs. There is likely another reason that the group that saw their livelihood jump into the ocean would want Jesus to leave that the writers want you to think.
