Jesus says that we are the “salt of the earth” (Matthew 5:13). In earlier posts, we looked at the properties of salt and applied them to evangelism and missions. In this final post, I want to conclude with one of the common usages for salt, and that is to preserve food. Salt is used to help preserve, purify, and protect by preventing decay.
Prior to refrigeration, salt was a necessary ingredient to keep food, especially meats and poultry, from spoiling. “Because of its hygroscopic properties, salting [was] an effective method of food preservation historically; the salt draws water out of bacteria through osmotic pressure, keeping it from reproducing, a major source of food spoilage.” (Sodium Chloride, Wikipedia)
As salt of the earth, we act as a preservative in society by taking a stand against that which is evil and taking a stand for that which is good in God’s eyes. “Believers are a restraint upon the world’s corruption. Unbelievers are often kept from evil deeds because of a moral consciousness traceable to Christian influence.” (The Wycliffe Bible Commentary)
Whether through our voices or through our votes…whether in our communities or in our country, let us live in such a way that we preserve what’s good and prevent moral decay in society. When believers do so collectively, the cumulative effect, like many grains of salt, become an even more powerful agent for good. So, if we are willing to take a stand individually for Christ, can you imagine how effective our witness will be when we stand together in unity with like-minded believers for good and for the gospel of Christ? (See John 17:20-23 for how our unity impacts evangelism.)
