Matthew 12:43-45 “When an evil[a] spirit leaves a person, it goes into the desert, seeking rest but finding none.44 Then it says, ‘I will return to the person I came from.’ So it returns and finds its former home empty, swept, and in order.45 Then the spirit finds seven other spirits more evil than itself, and they all enter the person and live there. And so that person is worse off than before. That will be the experience of this evil generation.”
