Since you have heard about Jesus and have learned the truth that comes from him, throw off your old sinful nature and your former way of life, which is corrupted by lust and deception. Instead, let the Spirit renew your thoughts and attitudes. Put on your new nature, created to be like God—truly righteous and holy. [Ephesians 4:21-23 (NLT)]
In both Matthew 12 and Luke 11, Jesus tells a rather confusing parable about a demon. After leaving a person, it searches for rest; finding none, the demon returns to its former home. Discovering it empty, swept, and in order, the demon brings seven more demons to live there. A rather puzzling parable, I can’t help but think of the phrase, “Nature abhors a vacuum.” First postulated in 485 BC by Parminedes and restated around 350 BC by Aristotle, it states that empty space is unnatural and goes against the laws of physics; therefore, every empty space in nature needs to be filled. I know nothing of vacuum theory, physics, or thermodynamics but, from this parable, it appears that sin abhors an empty mind or, as my mother used to say, “An idle mind is the devil’s playground!” I don’t know if Jesus was familiar with the Greek philosophers but, having exorcised several demons, he certainly was familiar with them. Empty minds and hearts must be filled by something—if not by God and good, then sin and evil.
Nevertheless, there seems to be more to this parable. Having just healed a demon-possessed man, Jesus was speaking to the Pharisees and scribes, people he frequently criticized for being more concerned with appearing righteous than actually being righteous. When reading that the house had been put in order, we probably think of it as neat and organized (like a file cabinet). The original Greek, however, used the word kosmeo which means to adorn, beautify or make attractive by having the right arrangement and the King James translation, which uses “garnished” instead of “put in order,” is probably closer to the original meaning. Kosmeo is the root word of cosmetics. While make-up may conceal, enhance, and even deceive, it does not change the underlying reality. The house may have looked good but the demons weren’t tricked and moved right back in. Sin isn’t deceived by appearances and will always return to hollow hearts and empty lives. Although God will take away our sins and banish our demons, it’s not enough to sweep out the old and redecorate; we must fill our lives with the new!
While they may look fine from the street, empty homes don’t do well; eventually they succumb to vermin like ants, box elder bugs, flies, termites, dust, spiders, mold, leaks, and dry rot. Empty lives are no different; they soon will be filled with demons like selfishness, anger, greed, addiction, pride, lust, pessimism, scorn, envy, prejudice and hate. But, if those same lives are filled with the love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control that come from the Holy Spirit, there will be no room for demons.
The first and the great work of a Christian is about his heart. Do not be content with seeming to do good in “outward acts” while your heart is bad, and you are a stranger to the greater internal heart duties. See that your chief study be about your heart—that there God’s image may be planted; that there His interests be advanced; that there the world and flesh are subdued; that there the love of every sin is cast out; that there the love of holiness grows.
