In this context, I realize that this applies to both types of houses.
We are a house of "spirits," that is, ideas, information, and a conglomerate of conflicting thoughts. If our conscious mind is strong, we can protect our private fief of interior mental territory. However, if our conscious mind is enslaved by worthless habits, dominated by thoughts tied to our "bellies" and not our hearts , our personal demons. Once our conscious mind is bound, our house can be spoiled. In Christ system, the heart (relationships, feeling) must direct the mind, not the belly (physical desires). A pure heart allows the mind to see God.
In a larger sense, organizations of people have the same weakness. Our strength is the head of our organization, which isn't necessarily a person. It can be the values that unite and organization that gives it a purpose. A house cannot be divided against its ideals, its meaning. However, once we tie up those ideas, bind the master of our house, then something, perhaps anything, can plunder the house, that the strong man, its strength protected. As with our bodies, our higher desires (our loyalty, our mission, our goals) must direct and organization, not its lower physical desires (pleasure, wealth, etc.). Organizations that follow their higher mission create value the brings wealth. Those that betray their mission for the sake of short-term gains, lose everything.
