Salt of the Earth. Light of the World. What Does that Mean?

In Jesus’ Sermon on the Mount, the phrases “salt of the earth” and “light of the world” are used to describe the role, the impact, and influence of Christians in this world, among men.  

Jesus says:

“Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men. 14 Ye are the light of the world. A city that is set on an hill cannot be hid. 15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. 16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.” Matthew 5:13-16

“the salt have lost it savour” – This means to become insipid or to lose flavor, vigor, interest.

“Never leave anyone the way you found them.” Let them see JESUS.

Their hearts cry out for Jesus, even if they don’t know yet that it’s Him that they need and are looking for.

“We would see Jesus.”  John 12:21

“Ye are …

“The salt of the earth”

salt preserves, salt cleanses, salt flavors

Never let your salt lose its flavor or your light to be covered, to grow dim.

“Quench not the Spirit.” 1 Thessalonians 5:19

“Salt is good: but if the salt have lost his savour, wherewith shall it be seasoned? 35 It is neither fit for the land, nor yet for the dunghill; but men cast it out. He that hath ears to hear, let him hear.” Luke 14:34-35

“a    [Salt is good …] The 33rd parable in Luke (Luk_14:34-35), illustrating the fact that if Christians backslide and lose their savor they are not fit for God or man (Mat_24:51; Mat_25:30; Luk_9:62; Rom_6:16-23; Rom_8:12-13; 1Co_9:27; Gal_5:19-21; Gal_6:7-8; Heb_6:4-9; Heb_10:26-29; 2Pe_2:20-22). Next, Luk_15:4.
b    [but if the salt have lost his savour, wherewith shall it be seasoned?] Question 101. Next, Luk_15:4. Salt loses its savor when exposed to the rain, sun, and air. What about believers who are the salt of the earth? Is there a possibility of their losing the life that makes them the salt of the earth? If there is no possibility, then there is no meaning to such statements as here and in Mat_5:13; Mrk_9:49-50.” Dake

In this “salt of the earth” parable, Jesus tells His followers that they are meant to be a potent and preserving influence, like salt that preserves and enhances, and to be a source of light, illuminating the world through their actions and lives. The truth is that the lives of salt-of Christ-saints are what results in the salvation, the preservation of eternal souls.

Here’s a more detailed explanation:

The Illustration:

Jesus uses the image of “salt of the earth” to describe the role of His followers in the world as they spread His glorious Gospel, obeying His Great Commission mandate.

Purpose of Salt:

In ancient times, salt was used to preserve and add flavor to food.

Meaning for Followers:

Jesus is saying that His followers should make a powerful impact, just like salt, preserving the eternal souls of men by preaching and teaching the saving Gospel of Jesus Christ in their world.

Jesus also says that His followers are “the light of the world,” meaning they should shine brightly in the way they live and as they speak the light of His truth into the hearts of those around them.

“14:34, 35 Salt is a picture of a disciple. There is something wholesome and commendable about a person who is living devotedly and sacrificially for the Lord. But then we read of salt that has lost its flavor. Modern table salt cannot lose its savor because it is pure salt. But in Bible lands, the salt was often mixed with various forms of impurity. Therefore it was possible for salt to be wasted away and for a residue to remain in the container. But this residue was worthless. It could not even be used for fertilizing the land. It had to be discarded.

The picture is of a disciple who starts off brilliantly, and then goes back on his vows. The disciple has one basic reason for existence; if he fails to fulfill that reason, then he is a pitiable object. We read concerning the salt that ‘men throw it out.’ … men throw it out, that is, they trample underfoot the testimony of one who began to build and was not able to finish. Kelly notes:

“There is shown the danger of what begins well turning out ill. What is there in the world so useless as salt when it has lost the one property for which it is valued? It is worse than useless for any other purpose. So with the disciple who ceases to be Christ’s disciple. He is not suited for the world’s purposes, and he has forsaken God’s. He has too much light or knowledge for entering into the vanities and sins of the world, and he has no enjoyment of grace and truth to keep him in the path of Christ. … Savourless salt becomes an object of contempt and judgment.’

The Lord Jesus closed the message on discipleship with the words ‘He who has ears to hear, let him hear!’ These words imply that not everyone will have the willingness to listen to the stringent terms of discipleship. But if a person is willing to follow the Lord Jesus, no matter what the cost may be, then he should hear and follow.” Believer’s Bible Commentary

“5:13 Jesus likened His disciples to salt. They were to the world what salt is in everyday life: salt seasons food; it hinders the spread of corruption; it creates thirst; it brings out the flavor. So His followers add piquancy to human society, serve as a preservative, and make others long for the righteousness described in the preceding verses.

The disciple has one great function—to be the salt of the earth by living out the terms of discipleship listed in the Beatitudes and throughout the rest of the Sermon. If he fails to exhibit this spiritual reality, men will tread his testimony under their feet. The world has only contempt for an undedicated believer.” Believer’s Bible Commentary

Depending on the heart soil of the person the salt (God’s Word) falls on, there will be a reaction. Some will delight. Some will rebel and persecute (vv. 10-12).

Every definition to be found about salt, along with our own personal experience, reveals that salt cleanses and salt preserves. It’s also full of minerals to nourish.

Another source notes the following about Jesus’ people in the earth being “the salt of the earth.”

“In Matthew 5:13, Jesus calls his followers ‘the salt of the earth,’ implying they should positively impact the world, preserving good and enhancing life, much like salt does to food.

Here’s a more detailed explanation:

Symbolism of Salt:

In Jesus’ time, salt was a valuable commodity used for seasoning, preserving food, and symbolizing purity and covenant.

Preservation and Influence:

By calling his followers ‘salt,’ Jesus suggests they should act as a preserving force in the world, preventing decay and promoting goodness.

Enhancing Life:

Just as salt enhances the flavor of food, Jesus’ followers should positively influence and enrich the lives of others.

Losing Saltiness:

Jesus warns that if followers fail to live out their faith and influence the world positively, they become like ‘tasteless salt,’ useless and discarded.

Living Out Faith:

To remain ‘salty,’ Jesus’ followers are called to live a life of faith, love, and service, making a positive impact on the world around them.”

“The light of the world”

Think about when the electricity goes out. Do you scramble around in the pitch dark to light a candle only to hide it, only to cover, to put something over it? No.

“Bushel” (v. 15) is referring to a basket or barrel, was in covering the light of a candle under it and we know that can lead to that fire being extinguished.

“May our lights shine before men, that they may see our good works, and glorify our Father who is in heaven. Matthew 5:16.” Karen Cochran

YOUR PRAYER: Father in Jesus’ name, I ask You to forgive my self-idolatry, rebellion, and wickedness and how I’ve done nothing to declare Your truth, to stand up and speak out for the innocent. Please wash me clean in Your precious blood dear LORD. In Jesus’ name.

Victory's Prescription with Judge Travis Bryan III [podcast]

Without His Cross Prescription, we cannot follow Jesus (Luke 9:23-24). “He must increase, but I must decrease.” John 3:30 “Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body. 11 For we which live are alway delivered unto death for Jesus’ sake, that the life also of Jesus might be made manifest in our mortal flesh. 12 So then death worketh in us, but life in you.” 2 Corinthians 4:10-12 “I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in […]

What is the Great Commission? [podcast]

What is the Great Commission? Who gave it? Who was the Great Commission given to? The Great Commission is simply the spreading of Jesus’ Word by teaching it to the world. Jesus gave it. He gave it to all of His people and holds each of them personally responsible for fulfilling it. Each of us will give full account to Him in this specific matter when we stand to be judged by Him. The Great Commission “And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 19 Go ye therefore, and […]
