Matthew 12:43 “When the unclean spirit has gone out of a person, it passes through waterless places seeking rest, but finds none. [44] Then it says, ‘I will return to my house from which I came.’ And when it comes, it finds the house empty, swept, and put in order. [45] Then it goes and brings with it seven other spirits more evil than itself, and they enter and dwell there, and the last state of that person is worse than the first. So also will it be with this evil generation.”

You can clean up your life outwardly, but without a changed heart, something worse will move in.
