The biblical view of reality and the connection between sickness and chaos

According to biblical authors, reality is seen as a small oasis of goodness and order surrounded by darkness. God created it with his powerful word. If God were to relax his sustaining word, chaos and death would consume the oasis. This understanding explains the depiction of sickness as an eruption of chaos onto the good ordered land. In biblical stories, sickness and demonic influence are closely linked.
