Jesus said, “When an unclean spirit goes out of a man, he goes through dry places, seeking rest, and finds none. Then he says, ‘I will return to my house from which I came.’ And when he comes, he finds it empty, swept, and put in order. Then he goes and takes with him seven other spirits more wicked than himself… and the last state of that man is worse than the first” (Matthew 12:43-45). Apparently, it is possible for the demons to come back if they find the place ’empty’ so the solution would be to fill it with the Lord, the Holy Spirit.
The person that got repossessed by demons (represented by the “house”) failed to take a firm stand for God. His intentions were good. He didn’t expect the return of the evil spirit and failed to submit his heart fully to Christ’s control. Submission to Christ meant giving up some of the cherished sins which he was not ready to repent of. Had he surrendered to Christ, he would have gained new power from the Lord to chase away all evil (Rom. 6:16), and the unclean spirit would not been able to enter into his heart.
The Christian religion does not consist mainly in abstaining from evil, but rather in diligently following the Lord by His grace. It is not enough that demons, whether literal or figurative, be cast out of the heart and mind; the Spirit of God must come into the life and be placed in control of thought and conduct (Ephesians 2:22).
Too often those who have been delivered from the disease of sin experience a relapse and become weaker spiritually than they were at first. Not realizing how careful they must be to run away from temptation and to engulf themselves with good influences, they expose themselves unnecessarily to evil influences and experience deadly results.
Our only safety is in complete surrender to the Lord so that He may live out His perfect life within us (Galatians 2:20; Revelation 3:20). This parable is a serious warning against mere surface improvement; it is not enough to reject the evil, we must diligently “seek those things which are above” (Colossians 3:1, 2).
