We are not possessed by evil spirits. We are possessed by our possessions. The more we have, the more we think about what we have. Note Jesus’ attempted exorcism of the rich young ruler, whom he loved. It didn’t work.
When Hollywood goes to the beach, we get Jaws. When it goes to church, we get exorcism. But sharks are innocent, and we are not possessed by evil spirits. We are possessed by our own minds, by the thoughts we think. Worry is possession.
