“Now when the unclean spirit goes out of a man, it passes through waterless places, seeking rest, and does not find it. Then it says, ‘I will return to my house from which I came’; and when it comes, it finds it unoccupied, swept, and put in order. Then it goes, and takes along with it seven other spirits more wicked than itself, and they go in and live there; and the last state of that man becomes worse than the first.” Matthew 12:43-45
“Through fear of imprisonment, disease, social stigma, financial ruin, and many other such motivations, a person can manage to rid himself of certain sinful habits. Sometimes the motive is more positive and the person determines to change because of love for a wife, husband, or children. But such self-cleansing—no matter how thorough and extensive and no matter what motivation—is never permanent. Even if the cleansing is by the Lord, it is not permanent if not accompanied by saving faith in Him. Surely many of the people whom Jesus cleansed of demons died and joined those demons in hell, because they did not accept the Lord’s forgiveness and offer of salvation. The vast majority of those to whom Jesus ministered accepted only temporary healing from disease and temporary relief from demonic control. They surrendered the symptoms and consequences of sin to Him, but not sin itself. Of the ten leper’s Jesus cleansed on one occasion, only one received the true wholeness of salvation (Luke 17:11-19).
When the basic sin nature is not dealt with through the miracle of repentance and trust in Christ, the removal of a particular sin or even a demon leaves a person’s spiritual house…unoccupied, swept, and put in order, but subject to occupation by seven other spirits more wicked than the first. And they go in and live there; and the last state of that man becomes worse than the first.
A religious, self-righteous, reformed person is subject to Satan in a way that a guilt-ridden immoral person is not, because his very morality blinds him to his basic sinful condition and need. He is perfectly satisfied with his empty house, thinking that freedom from outward manifestation of sin is freedom from its presence, power, and damnation.”
