Outside the rich West, overeating and lack of physical exercise are a whole lot lower on the list of problems. It's rare to see people's bodies atrophy from lack of use — unless there is so little food that people don't have the strength to move around much.

Getting and keeping physically fit, and not over-indulging in food, does not have to be an ego-serving idol — it can be an act of humility and respect. And our renewed energy and physical strength can allow us more options to serve Christ.
