SALT of the EARTH
Question: What did Jesus mean when he said we should be the salt of the earth?
Answer: The interesting thing about salt is that although it is essential to life and good health on planet earth, too much of it can be harmful. Blood, sweat and tears are this mineral in them. Its importance has lasted for several millennia.
Anciently, the mineral provided the financial support for pursuits like art. In Roman times, it was so precious it provided a means to pay soldiers. Salt received the nickname of 'white gold' sometime during the Middle Ages. Our English word salary comes from the word salarium, a name given to the mineral when it functioned as currency.
Jesus, during his famous sermon given on a mount, stated that believers were the 'salt of the earth' and warned that it was possible for them to lose their 'saltiness.' If believers lost their "flavor," they would be of no benefit to others. They would then only be worthy of being "thrown out and trampled upon by men" (Matthew 5:13). We begin to find our answer regarding the meaning of what Jesus stated by noting the context in which it was given.
Jesus tells those wishing to follow him that they must make a difference in the world. The difference made is "the flavor" or the good works believers are to do that are to shine like a light on a lampstand and offer a witness for Christ.
Consider that for many years salt was used as an agent to slow the decay of meat and other foods so that they could be edible for a longer period. Christians who obey God and do his will act as a preservative of the human race and the earth by slowing down the moral and spiritual decay of the world around them.
Making a difference, however, even includes even more than our actions. According to the apostle Paul, we must also use our words like salt to season or benefit those we talk to (Colossians 4:5 - 6).
