Suppose you had been house hunting in a development of new homes, and when you found an empty one you tried to get into it. If the house was full, occupied by people, you wouldn’t dare try to get in. That’s exactly what Satan does. He looks for vacuums. He looks for empty houses. They may be clean, but if God is not within you, having made you His temple, you can be sure the devil is going to occupy you.
Be filled with the Spirit of God. That’s the warning and meaning of this parable of our Lord in
24 “When the unclean spirit goes out of a man, it passes through waterless places seeking rest, and not finding any, it says, ‘I will return to my house from which I came.’
25 “And when it comes, it finds it swept and put in order.
26 “Then it goes and takes along seven other spirits more evil than itself, and they go in and live there; and the last state of that man becomes worse than the first.”
