Thinking in Vanuatu: Temporary dwelling

Vanuatu's capital, Port Vila, has residents from all over the archipelago's 80+ islands. Technically speaking, there is no "custom land" ownership in the municipality, rather all the land is leased out by the government. In the areas in and around Port Vila, there are a lot of nationals who are essentially "squatting" on land that is not their own.

Nevertheless, I had always found it odd that even people who have relatively good paying jobs still live in shacks made of pieced-together materials such as cardboard, corrugated roofing iron, masonite and tarpaulins. Why don't these people, who have the financial means to do so, save up some money and build a proper cement block house? Well, it's because they understand their dwelling to be temporary. Since they don't really have a right to live on the land where they are, and could therefore potentially be kicked out at any time, they are understandably hesitant to put down roots. As it now stands, if they are forced to move on, they really won't be out any money, and since they're content, I guess it makes total sense.

Which got me to thinking, perhaps we Christians, whose "citizenship is in heaven," should have a more temporary-dwelling mentality as we live here on earth. After all, we too are just a'passin thru. The situation has convicted me to think more about storing up treasures in heaven, rather than here on earth. How about you? Where is your focus?
