First, salt is a preservative . Before the days of refrigeration, meat was packed in layers of salt to preserve the meat until it could be consumed. There is a storage facility in Kansas where everything from court documents to original classic film negatives are stored in a salt formation for preservation. Our church should preserve our community, keep it from spoiling. Second, salt adds flavor .
Christians always confront worldly views.
We flavor our culture. Third, salt causes thirst . People who are exposed to excessive heat take salt tablets to increase their bodies' craving for water. Their salt-induced thirst prevents dehydration and death. We are to be different from those around us that others will be thirsty for our lifestyle.
