During a cooking session with my cousin this summer he recommended using Kosher or Sea Salt for cooking. Although I’ve seen these particular salts in recipes, I’ve been quite curious since our summer cooking debut, and did some research on salt both from a cooking and spiritual perspective.
Salt is a mineral substance composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of ionic salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is one of the oldest and most ubiquitous of food seasonings, and salting is an important method of food preservation (Wikipedia)
The role of salt in the bible was significant in both the Old and New Testament. Salt was very valuable, and used as a seasoning, preservative, disinfectant, in ceremonial offerings, and as a unit of exchange.
Matthew 5:13 “You are the salt of the earth; but if the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men. (NKJV)
In this verse Jesus was calling his disciples “salt”? And, how could salt “lose its flavour”? By becoming contaminated. What can contaminate salt? It can become mixed with dirt (earth). Dust and dirt in combination with water and air can change salt into something else. Such salt cannot be used in food.
Our lives can also be contaminated by the impurities of the world, by not living by His Word, and doing things that aren’t pleasing to Him. When are lives are contaminated, we can no longer be used to disciple others. As Christians our task is to be the salt of society, preserving, reconciling, adding taste, giving meaning where there is no meaning, giving hope where there is no hope.
There are many types of salts, and using the right salt can make all the difference in the world. Here are a few varieties, and when to use them:
(1) As a seasoning agent, salt improves the taste of the food that it comes into contact with. Be the salt in someone’s life.
(2) Salt makes people thirsty. Seek to create a thirst in people’s lives. Live by the Holy Spirit so that others will thirst for the peace and blessings in your life.
(3) Salt is used to thaw ice. Use your salt to warm hearts.
(4) Salt is used as a preservative. Preserve the faith, and speak the truth to others.
