How To Be The Salt Of The Earth

How To Be The Salt Of The Earth September 10, 2018

What did Jesus mean by telling the disciples that they are the salt of the earth? What does that mean?

The Essential Mineral

Salt is a necessary mineral and so important that it was used as a currency in ancient times, and it’s where we get our word “salary” from, but for thousands of years, salt’s been used as a preservative, preventing spoilage in foods, particularly meat. Biologically, humans cannot life without salt. Jesus said salt is good (Mark 9:50), but He said that for more than a physical reason. He, as the Creator of life, must know that salt is essential to human life. Paul says our speech is to be seasoned as salt (Col 4:6), so why all these Scriptures about salt? And what does it mean to have salt in our speech? Is this tied to our behavior? We know that salt is important as a preservative, and was even offered in some of the Old Testament sacrifices. If we have this (sweet) speech among believers and the unsaved, then we are more likely to have peace with one another (Mark 9:50). Our salt can enhance the flavor of any conversation or serving opportunity. Salt can be any of these three E’s. I call them the 3 “E-migos:” Encouragement (to give courage), Edification (building others up) and Exhorting (to adjure, urge, or call upon). This does not mean cramming our beliefs down people’s throat. Too much salt ruins the flavor. It’s like someone left the cap loose on the salt shaker, and all the salt dumps out and ruins the food, however, just enough salt can make things more palatable. You can lead a horse to water, but you can’t make him drink…but, you can feed him salty peanuts.

A Sanitizer

Salt enhances flavor, and it acts as a preservative, but it also acts as a cleanser or sanitizer, and in our family, gargling with warm salt water has cured many a sore throat over the years, but salt has also been used as a cleanser as well. A guy at work always used salt and crushed ice to clean the coffee pot stains, and even when someone had left the coffee pot on overnight, the combination of crushed ice and salt made it easier to clean the coffee pot. Today, most coffee makers will automatically shut down if left unattended, but you’ll find sodium chloride in many medicines, and during wartimes, it was used as a wound sterilizer and germ killer. Salt is good…unless you use too much. Then, it ruins everything it touches. One example of salty speech was when one of our church members was gone for a couple of weeks. When they came the following Sunday, one man said, “Well, where you have you been?” Instead, it would have been better to ask, “How are you? We missed you last week. Are things okay?” One seems a bit judgmental while the other is salted with the sweet speech of concern for their well-being. One leaves a bitter taste in the mouth; the other is comforting.

Human Survival

Salt is vital for many purposes, but it’s essential to our own physical survival, however, if regular salt loses its flavor, then it becomes worthless and it’s simply thrown away (Matt 5:13). If it’s left in the open air and exposed to the elements, the moisture ruins it. Salt like that is good for nothing, but pure salt has great value in this world, but I believe most of all, it have value in our speech and in our life. God may use our salty speech to bring people to Christ or to show the love of Christ by which they can know who His disciples are (John 13:34-35). In that way, He will preserve them for all eternity, becoming incorruptible someday (1 Cor 15), and He is able to keep them forever. Jesus says, “All that the Father gives me will come to me, and whoever comes to me I will never cast out” (John 6:37), so “that I should lose nothing of all that he has given me, but raise it up on the last day” (John 6:39). That means, “No man can pluck them out of my hand, nor…out of my Father’s hand” (John 10:28-29). You cannot be any more preserved than to be preserved by God Himself.

Worth their Salt

You’ve probably heard the saying, “he ain’t worth his salt.” That saying is based upon the salary he or she drew for the day, and whether he or she really worked hard that day, thereby earning it or being deserving of it. Some Roman soldiers were paid partly in salt, so to be worth your salt means you are earning your wages or deserving of what you receive. That means there is worth in what you do, but when it comes to salvation, worth has nothing to do with it…unless you’re talking about Jesus Christ’s worth! One precious drop of His blood is the most valuable thing in the universe, because under it the sinner’s plunged and is raised in victory. The important thing is that our worth is not why we got saved. It was only a matter of God’s free gift of grace. Our works had nothing to do with it, just as our human worth didn’t warrant our salvation. It was simply an act of love on God’s part (Eph 1:4, 2:8-9).

Seasoned with Salt

Jesus spoke about being the salt of the earth, and doing so for a dead and decaying world. He said, “Salt is good, but if the salt has lost its saltiness, how will you make it salty again? Have salt in yourselves, and be at peace with one another” (Mark 9:50). This means that if we have saltiness in ourselves, it will show up in our words, and that saltiness can make us “be at peace with one another,” and that’s a worthy goal, isn’t it? The Apostle Paul said to “Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person” (Col 4:6), so our words to others, being “seasoned with salt,” will consist of knowing “how [we] ought to answer each person” when asked about the hope that is in us. Our response should always be with gentleness and respect (1 Pet 3:15), and in this way, we can “be at peace with one another,” perhaps even unbelievers.


Sometimes our words betray what’s in our heart. For example, when we begin to debate or argue with unbelievers, we can get worked up about things, and our language may be anything but salty. On the other hand, too much salt ruins the conversation. It’s like trying to enjoy a good meal. Using a little bit of salt is perfect, but too much salt ruins it, so there must be a balance. Too much can make it unpalatable, but too little can make it bland. Jesus said, “You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people’s feet” (Matt 5:13). Just like salt that’s left open and exposed to the world, we can lose our saltiness. If that happens, it’s not good for anything but to throw away, however, that’s not what salt was intended for. It was meant for our survival, but it was also mean to make our speech a sweet, savory.
