What Being the "Salt of the Earth" Means

6/15/2022

Every Christian knows Jesus’ words that his followers were to be the “salt of the earth” and the “light of the world” (Matthew 5:13-16).  Being the light of the world seems easy to understand – it clearly involves the responsibility to “illuminate” the world through the witness of our lives and, of course, to reflect the light of the God who himself can be described as “Light.”

​But what about the salt – what exactly does that represent?  Salt was used for many different purposes in the Middle East during the first century, so there are a number of possibilities regarding what Jesus intended. We should consider all of the most likely meanings.

1. Perhaps the most obvious possibility is that Jesus’ reference to our being “salt” has to do with the use of salt as a flavor enhancer (Job 6:6) –  that we are to make the world more pleasing or “palatable” to God (Romans 8:8).

2. Salt was also widely used to preserve food, especially meat which would spoil quickly in the heat of the Palestinian desert environment.   The sense of long-lasting preservation is seen in the biblical expression “a covenant of salt” (2 Chronicles 13:5).

3. Salt was utilized to purify things such as offerings made in the tabernacle or temple (Leviticus 2:13).  This is the meaning behind Jesus’ words “For everyone will be salted with fire ...” (Mark 9:49) and Paul’s words “Let your conversation be always full of grace, seasoned with salt” (Colossians 4:6).

4. On the other hand, the ability of large quantities of salt to kill vegetation and render land unusable led to salt being used metaphorically for the concept of emptiness and destruction (Job 39:6, Ezekiel 16:4, etc.). 

5. Despite the fact that large quantities of salt kill all plants, much smaller quantities were used as the world’s oldest chemical fertilizer.  In fact, after vegetation has been killed by a heavy application of salt, the plants often eventually come back more profusely.  Because the word “earth” in Jesus’ expression “you are the salt of the earth” can mean “soil,” some commentators feel that he may have meant his followers were to bring new life to the world, like a little salt to soil; but the likelihood of this meaning is certainly unsure in this context. 

6. Ancient peoples also often put salt on the wicks of oil lamps to cut smoke and increase their brightness.  This meaning seems attractive as the use of salt in this sense would then be parallel with light, in believers being both “salt and light.”  But in Jesus’ words in Matthew 5:13-16, salt is discussed before light is mentioned, indicating he probably had a more common use of salt in mind.

Many other meanings have been claimed for Jesus’ words based on other uses or characteristics of salt. For example, some have claimed that just like salt, believers can make the world thirsty for God’s truth.  But this and similar ideas are somewhat fanciful and would not have been understandable in the context of what Jesus said without explanation. Likewise, it is commonly thought that Roman soldiers were paid in salt (hence the word “salary”), so that salt might have been a symbol of the disciples’ “worth,” but in fact the Empire’s soldiers were paid in normal money (or not at all), but not with salt.

Because Jesus did not explain which aspect of salt he intended in using the metaphor, we must presume that he had the most basic aspect in mind, which would mean that either or both meanings 1 and 3 above – salt as a flavor enhancer or a purifier – are most likely what he had in mind and how his hearers would have understood the expression. Understood in either of these ways, being the “salt” of the earth would certainly mean that we represent the world to God, just as in being the light of the world we represent God to humanity (Matthew 5:16).

But Jesus’ words also hold some practical aspects in his use of salt as a metaphor. After saying “you are the salt of the earth,” Jesus proceeded to say “But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men” (Matthew 5:13). This is interesting as salt cannot actually lose its saltiness unless it is diluted by water or mixed with other substances. Salt spoiled in such a way might often have simply been thrown out on the street, and it is also possible that such low grade salt was spread on Roman roads to inhibit vegetation growth. In either case it would be “trampled by men,” but the lesson would be that our belief and behavior must not be diluted by things of the world around us.

There is another way that spiritually we might lose our “saltiness.”  Jesus also told his disciples “Salt is good, but if it loses its saltiness, how can you make it salty again? Have salt among yourselves, and be at peace with each other” (Mark 9:50, emphasis added). This suggests that our saltiness can be lost through a lack of peace with one another, and that we may cease to fulfill our function of making the world more acceptable to God by our “saltiness” either being diluted, as we saw above, or by not living peaceably with others.   These obstacles to successful discipleship are both worth thinking about.  ​

Trust – The Foundation of Faith, Hope, and Love

6/1/2022

When we read the apostle Paul’s great “Faith, Hope, and Love” summation of the most important qualities in the Christian life (1 Corinthians 13:13), it is sometimes  easy to forget the importance of other spiritual qualities that support that great triad.  One such quality is trust, which actually underlies all of Paul’s “Big Three” and enables each one to function.
​
Faith and Trust

There is a good deal of overlap between the words faith and trust in English, but they are also different.  At the most basic level, faith is a noun – it is something we have or are given. Trust is primarily a verb; it is something we do.  This is true in the Bible, also.  Although the same Hebrew and Greek words are translated as both “faith” and “trust” in the English Bible, context and the form of the words  show us whether faith or trust is meant.    
 
How does the difference between faith and trust affect us? To use a physical analogy, we believe that aircraft can fly – we probably have absolute faith in that fact – but to board a plane for a flight we also must trust the pilot. If we suspect the pilot is inebriated we might get off the plane immediately – we have faith that it can fly safely, but we do not trust that it will.
 
In the same way, we can have faith in something or someone and still not trust them.  The prophet Jonah is a Biblical example of this – Jonah had faith in God, but did not trust him (Jonah 4:2). In the New Testament, the apostle James tells us that even demons believe in God (James 2:19). They have “faith” that God exists , but they do not choose to trust and follow him.  So it is not enough to just have faith in God, we must also trust him – and the connection between faith and trust is a two-way street.  On the one hand, trust is our active response to what we already have faith in, but on the other hand, the more we develop our trust in God, the more our faith grows with it.

Hope and Trust

Hope and trust are also directly related.  If we do not really trust any person controlling a situation in which we are involved, we will have very little hope in the outcome.  That is why our trust in God is so important for a life that is truly based on hope.  We can see this principle in the book of Romans: “May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit” (Romans 15:13).   Here, Paul clearly tells us that we will be filled with the joy and peace that come from hope “as” or to the degree that we trust in God – and he stresses that fact a second time in the same verse by telling us a result of trusting God is that we will overflow with hope!

This is a principle found throughout the Bible – it is only to the extent that we trust God that we will really look forward with hope for this life and the next.  In the apostle John’s description of his vision of the new heaven and earth he tells us “He who was seated on the throne said, ‘I am making everything new!’ Then he said, ‘Write this down, for these words are trustworthy and true’” (Revelation 21:5).  John reminds us that we can look forward to  renewed  life in a renewed world precisely because God is trustworthy – we can hope because we can trust!

Love and Trust

There is an old proverb that “When mistrust comes in, loves goes out” and it has often been said that we cannot deeply love those we cannot really trust because the foundation of all love is trust.  This principle  is often as true spiritually as it is physically.  Even if we say that God is able to love us with a perfect love that needs no trust, this may be true, but theologians have argued that ultimately  God’s love is based on trust in his own power to eventually bring us to love him. 

But whatever the case may be regarding God’s love for us, it is clear that our love for God, and for others, is largely built on trust.   We love God because we have first been loved (1 John 4:19), but our response to that love is based on our trust – just as David says in the Psalms: “But I trust in your unfailing love …” (Psalm 13:5).

Trust usually precedes love and is always needed to maintain it.  Trust is the glue that holds relationships together and allows them to grow.  We must be willing to extend trust to those we want to love, and we  must give ultimate trust to the One who has given us ultimate love.

The Foundation of Trust

So trust really does function as the foundation of faith, hope, and love.  But while faith, hope, and love are all ultimately gifts given to us by God, we must remember that our willingness to trust underlies the effectiveness of those gifts.  Faith, hope, and love are all doomed to falter and certainly will not grow if trust is not our response to these qualities.  It is as we learn to trust God fully that our faith is strengthened, our hope is increased, and our love grows.   Faith, hope, and love may be the most important spiritual qualities in our lives, but we must actively apply trust to receive and to grow in them.  

So how do we develop our trust in God?  In any relationship, we develop trust in someone by getting to know them and seeing that they are trustworthy.  God is completely trustworthy, of course, and the Bible shows that unequivocally:   “God is not human, that he should lie,  not a human being, that he should change his mind. Does he speak and then not act?  Does he promise and not fulfill?” (Numbers 23:19 ). But because humans  are the way we are, most of us need to see that trustworthiness  in our lives to fully appreciate it and to respond to it.  

We do that in two ways – by getting to know God better through the study of his word – where we see countless examples of rewarded trust – and by paying close attention to the events in our own lives and the lives of others where God is clearly acting.  Gratitude plays a role here, too. If we are noticing and giving thanks on a daily basis for even the smallest things in life that show God’s help, we will  usually find that our trust grows quickly.  And as it does, so will the faith, hope, and love in our lives.
