What does the Bible say about being possessed by demons?

In Mark 5, we witness a vivid account of a man possessed by demons, emphasizing his intense misery and inability to help himself. Controlled by unclean spirits, he demonstrated the devastating effects of demonic possession and was utterly without hope until he encountered Jesus. This story serves as a powerful metaphor for all sinners, revealing the total inability to liberate ourselves from our spiritual bondage without divine intervention. The man's experience exemplifies how sin enslaves individuals and leads them down a path of destruction without Christ's saving grace.
