Resonant Light
June 8, 2025
A life of faith isn’t meant to stay quiet or hidden. When we truly walk in the way of Jesus, our lives begin to resonate—spreading the light of God’s goodness, truth, and love to those around us. This week, we’ll explore what it means to be a people whose faith not only reflects Christ but also influences others in ways that are lasting and life-giving. Just as light travels and echoes beyond its source, so does a kingdom life lived with purpose and compassion.
Resonant Light
Echoes of the Kingdom Week 2
Lauren Wachter
I'm so glad you're here. So I assume a lot of you don't know who I am. So I wanted to start
by introducing myself. My name is Lauren, and this is my family here. My husband's name is
Tristan. Our oldest boy, Kieran, is 13, and he's now taller than me. Thomas is nine and
currently loving baseball. Evie is four and she is a lover of all things horses and unicorns.
At the moment. Solomon is two and both he and Evie take dance classes. They just had a
recital last week. I, work part time as a para educator over at Adams Elementary with the
preschoolers, and in the past I have worked or volunteered at several daycares and schools
and preschool programs. So I'm very experienced and comfortable with kids.
It's just room for all. So it's getting me out of my comfort zone. Although I don't believe you
grow much inside your comfort zone. I am passionate about Jesus and His teachings, and
so I am so honored to be invited up here and really excited that we get to go through the
sermon on the Mount together. So you can see Matthew's account of this sermon as
Jesus's greatest hits.
If you want to know what Jesus is all about, look no further. It is Jesus's manifesto on
righteousness. He spells out for us the heart of what it means to follow him. Last week we
looked at the first 12 verses of Matthew chapter five, commonly called the Beatitudes.
There Jesus describes the kind of people to populate his kingdom.
It is countercultural. It does not describe the way the world seems to work. You see, in
God's kingdom, it's not the rich and powerful who are happy. It's not the strong or the self
reliant that are happy. It's not even the ones that have it all together that are happy. It's
actually the poor, the meek and the merciful. But this isn't the picture that the world around
us paints for us as it.
Jesus is in describing the rules of the world, or giving us tips on how to get ahead in life.
Instead, Jesus is offering us a whole new way to be human for the rest of the world. This
sermon seems to be upside down, but for Jesus as followers, for those of us in his kingdom,
it's right side up in the sermon on the Mount.
Jesus is teaching us what right side up really looks like, but it's going to take a refocus. So a
few weeks ago, I was in the van driving to church and listening to the radio, and I heard a
quote that just really stuck with me. And it was, you have to be different to make a
difference. We as Jesus's followers, should look upside down to the rest of the world.
We carry on Jesus's teachings and bring people stuck upside down, right side up in order to
make a difference. We have to be different. So today our focus is how we can be different.
Difference makers. We'd be looking at just four verses total this morning. So let's start by
reading the whole section. Matthew chapter five, verse 13 through 16 says, you are the salt
of the earth, but a 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. You are the light of the world. A city set on a hill cannot
be hidden. Nor do people light a lamp and put it under a basket, but on a stand. And it gives
light to all in the house.
In the same way, let your light shine before others, so that they may see your good works,
and give glory to your father who is in heaven. So Jesus here is giving us two metaphors.
Salt and light. Both salt and light change their surroundings for the better. They make a
difference. Salt does not blend in. It enhances by being different.
Light is the opposite of darkness. Light dispels darkness. The two do not coincide. These
metaphors work together, but each have their own nuances since they are unique in ways.
Let's look at each separately. Verse 13 said, you are the salt of the earth. Jesus is giving you
an identity. You are. Notice it doesn't say, I aspire to be the salt of the earth, or once you
become the salt of the earth.
It simply says you are the salt of the earth. If you are a follower of Jesus, he is giving you an
identity. Here. You are the salt of the earth. Okay, so what could this mean? What is Jesus
saying about our given identity by calling us the salt of the earth? Let's get some cultural
context. Since the salt that we go buy at the store today is very different than the salt in
Jesus's time and place.
So this is a picture of the salt formations in the Dead Sea, which is located about a day or
two's journey from where Jesus is likely teaching. The Dead Sea was and still is a resource
for salt harvesting in the area. They would either mine these formations directly or they
would collect seawater in a pan. Let the water evaporate out, leaving salt crystals.
Salt was very precious and expensive. Have you ever heard the phrase worth your salt? That
idiom actually originated in Rome, where some soldiers were known to be paid their wages
in salt. In fact, the Latin word for salary solarium is derived from sal, meaning salt. During
the time of Jesus, salt was used to seasoned food just like it is today.
But most importantly, it was used as a preservative. There were no refrigerators, so they
were dependent on salt to preserve their food in order to fight decay. They would pack meat
with lots of salt and not just a grain or two. So what do we learn about our given identity
from this cultural context? I think we can make some informed guesses of what Jesus might
have been communicating when he called his followers the salt of the earth.
Like salt, we are valuable to Jesus and His kingdom. Like salt. We seasoned the world.
When we show kindness in a world full of hate. We make the world a better place. Just like
salt makes food tastier. And like salt, we are a preservative. Salt preserves food. We
preserve the world. When we push against injustices. We fight the decay of the world
around us.
And like salt. We are most effective in a community when we are of one mind and mission.
So I think it's likely Jesus had one, or maybe even all of these meanings in mind when he
used salt as a metaphor to describe our identity. But Jesus had more to add to his
metaphor. Let's finish verse 13 says, 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 underfoot.
What is Jesus cautioning us against here? Consult. Lose it. Saltiness. Can salt lose what it
is? Well, today we know that. That would be ridiculous. You can't take sodium chloride and
change its very chemical makeup. But remember those salt formations? They were not
pure sodium chloride. Like our table. Salt is, but likely a mixture of sodium, magnesium,
and potassium.
When it would rain, the sodium chloride would be the first to dissolve. Now listen up. This
part's really important. Leaving a white powdery substance that looked like salt, but
without the effect of flavor or preserving properties, rendering it useless. But if 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 underfoot.
So this part of the verse is less fun to apply to ourselves. But just as important. So here's my
question. Do we represent Jesus purely or do we represent Jesus purely, or do we dilute his
teachings with other agendas? Until Jesus is no longer recognizable in what we do and say.
In the things we stand up for and the people we fight for, or maybe against.
Do we do pure Jesus? Or do we cut Jesus with cheaper substances to make him more
palatable? This mixing of agendas would happen slowly and without our full awareness.
And I believe this contamination is what Jesus is warning us about when he teaches about
salt losing its saltiness. Jesus gave us the identity of salt. We get the honor of representing
him and spreading his teachings to those around us, to flavor and preserve the world.
We can make the world around us a better place by being a positive influence to our family
and to our neighbors. We fight against the decay of the world by staying vigilant about
representing Jesus purely. Now when Jesus says, no longer good for anything. He is not
referring to his love for us. There's nothing we can do that will make him love us less.
However, he is speaking to our effectiveness in his kingdom. We can be confident in his
love for us while still asking ourselves, am I fully living into the blessing I was created to be
for the world? Am I changing my surroundings? Or are my surroundings changing me? So
let's get back to our Scripture and start in verse 14.
You are the light of the world. A city set on a hill cannot be hidden, nor do people light a
lamp and put it under a basket, but on a stand. And it gives light to all in the house. Jesus is
saying we are meant to be visible. Noticeable, like a city on a hill is noticeable like a lamp
on a stand is noticeable.
Light doesn't do any good. Hidden. We were made to stand out so that our presence brings
clarity, direction and hope to the world. The word you in this sentence, as well as in verse
13 is speaking of the collective group. Some people today might use the word y'all. Jesus is
all about community. Y'all.
This is not a new thing. This is not a me thing. This is an ass thing. First, Jesus calls us the
salt of the earth, and now he says we are the light of the world. He's adding another layer to
our identity. So let's look at some cultural context for light now. Since in Jesus's time there
was no electricity.
The concept of light would be very different than it is today. When the sun goes down here,
we just flip our light switches on and we stay up as late as we want. However, if you're a
parent of young children like I am not without consequences. In the morning. Although I
digress. In Jesus's time, once the sun went down, no more work got done.
They needed a light in order to do anything. But they weren't completely without hope
because they had these. Here's a picture of what lamps look like in that time. They put oil
inside, a wick was lit, and it would produce a similar amount of light as a candle. When
candlelight seems insignificant to us, when we compare it to our light bulbs.
But do not underestimate the difference this flame would make in a small house. It would
make sharing a meal or hanging out with your family possible. It would make community in
dark places possible. Remember, community is something Jesus is all about and I believe
he hints at it in his teachings often. Light as a metaphor in the Bible used to represent
wisdom or instruction.
And actually that's a metaphor we still use today. For instance, if you want to represent a
cartoon character being inspired, you could draw a light bulb above their head. If someone
has a good suggestion, we call it a bright idea. If we understand something better, we see
more clearly. Anyway, hopefully I've shed some light on the situation for you.
Wink, wink, came down with the bronze, I promise. Back to our scripture. Verse 15 says, nor
do people light a lamp and put it under a basket, but on a stand, and it gives light to all in
the house. So salt became ineffective by being contaminated. Light becomes, in fact
ineffective. By covering it up. We become watered down and unsalted without being
conscious of it.
But this basket, this basket is intentional. It is put on top of the lamp. Sometimes we hide
our light to avoid looking strange. But Jesus says being different is the very point. Being
different is light in a dark world. So what baskets cover your light? Is it fear? The first steps
of bold faith can be scary. Just like when kids learn how to walk, their first steps are not
confident.
But they do get back up and try again. Is a comparison or inferiority? See, I'm not
experienced at preaching like is. So why even try? Is your basket compromise when we
compromise Jesus standards in order to not offend or just to fit in? We are living upside
down. Salt and light unmistakably change their surroundings. Light dispels darkness. It
does not coexist with it.
Are we unmistakably Jesus followers? Do we look different from the world? Jesus uses the
metaphors of salt and light to remind us that we are different, and to urge us to make a
difference. Everywhere we go, we can make a positive difference for those around us. Jesus
wants us to realize that we are different so that we can make a difference.
Verse 16 says, in the same way, let your light shine before men, so that they may see your
good works and give glory to your father who is in heaven. Here is the ultimate why, in this
section of his sermon, the reason to be salt and light is to lead others to God. When we are
radically different, the rest of the world notices.
When we have their attention, we can invite them out of the dark, bland, upside down world
they are living in and into the lit and tasty right side up kingdom. You have to be different to
make a difference. Salt changes what it touches. Light changes what it touches. We were
created not to blend into the background of the world's brokenness, but to shine.
And in that light, people begin to see God more clearly. When the world offers hate, we offer
love. When the world warrants revenge. We forgive instead. And when the world tempts us
to gain power, we serve humbly. Instead. So are you. Salt? Are you light? The answer is yes.
If you chose to follow him, Jesus says, it's our identity.
The better question is, as salt and light, do we stand out as a positive difference? Am I fully
living into the blessing I was created to be for the world?
Well, dear God, I thank you for giving us this identity of salt and light. It is a high calling. But
God, we know that your Kingdom is. For those of us who know we need you. You promised
to always be there, to never leave us. We ask that this week we have opportunities to stand
up and stand out, and that you will give us boldness to do just that. Thank you for loving us
and for forgiving us as you do in the name of Jesus Christ. I pray. Amen.
