Recently a friend of mine read Jesus’ parable about the empty house of the soul, and the evil squatters who come back to take possession of it:
Luke 11.24–26 [24] “When the unclean spirit has gone out of a person, it wanders through waterless regions looking for a resting place, but not finding any, it says, ‘I will return to my house from which I came.’ [25] When it comes, it finds it swept and put in order*. [26] Then it goes and brings seven other spirits more evil than itself, and they enter and live there; and the last state of that person is worse than the first.” (*The parallel text in Matthew 12.43-45 makes it clear the house is “empty” as well)
