Salt was kind of a big deal in the first century. In fact, it was so important and valuable that Roman soldiers sometimes were paid in salt. Hence the expression, “He’s not worth his salt.”
Salt can make an impact as well. A little bit of salt will go a long way. Salt takes watermelon or cantaloupe to another level. Just a little works on oatmeal too. Salt also stops the rotting process. Without refrigeration in the first century, people would preserve meat by rubbing salt into it.
In the same way, a disciple of Jesus can stop the spread of evil. When something is wrong, a Christian can speak up for what is right—in a classroom, in an office, in a neighborhood, or in our culture. And most importantly, we can speak up for Jesus Christ.
The greatest compliment that can be paid to a Christian is when a nonbeliever says, “What is it about you? I admire you. I want to know what makes you tick.” You’ve done your job, Christian, because you’ve created thirst in another.
Jesus said, “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” (Matthew 5:13 NKJV). Flavorless salt is neither good for the soil nor for the manure pile. It’s thrown away. It’s like an espresso without caffeine.
In effect Jesus was saying, “What good is a halfhearted Christian? What good is a diluted believer? What good is a decaf disciple?” The answer is not much. Disciples of Jesus must impact their culture.
You are the salt of the earth. This means that as a disciple of Jesus, you are valuable. Your life can make difference.
