How Should Missionaries Choose Their Standard of Living?

"Adapting oneself to a new culture and worldview is never easy, and it does not happen automatically. Due to globalization, in many large cities of the world missionaries have the option of living in a quasi-Western bubble. They shop in Western-styled grocery stores, wear up-to-date Western fashions, maybe even take their kids to McDonalds on a regular basis.
The unpleasant truth is missionaries who uncritically follow this kind of lifestyle are unlikely to become bi-cultural.
However, rather than picking on the obvious extreme cases, this should serve as a reminder to all of us that we need to stop letting transnational corporations dictate our behavior. A missionary’s choice of lifestyle is just that—a choice—and one that we should be much more deliberate about since it sets the tone for much of what goes on in the rest of our ministry. I am not asserting it is morally wrong for missionaries to live a thoroughly Western lifestyle in the Majority World—this is not my call to make. But I am saying that such a choice can be massively harmful to the cause of Christ because it distorts the meaning of the gospel."
