Epiphany 5A
Dear saints of Our Savior~
Jesus says that you are the salt of the earth. And Jesus also says that you are the light of the world. These two majestic metaphors make up the heart of what’s come to be known as the “Sermon on the Mount.” I can hardly improve upon what Jesus has already proclaimed. So, if you don’t mind, let’s just lean into the words of Jesus and see where they take us.
You are the salt of the earth. And you are the light of the world. You—dear baptized believer, faithful follower of Jesus—you are salt and you are light. What does this mean?
First of all, notice the present tense: You are salt; you are light. This isn’t a demand or a command to be something you’re not. It’s not an order to try harder. And it’s not that you should aspire to be salt and light. It’s what you already are through faith in Jesus Christ.
Jesus’ followers knew that salt was a valuable and useful substance. Salt seasons and preserves. And you don’t need much to make a big difference. A dash here, a pinch there. But, oh, so necessary! You can’t be the chili champion of the church without salt. Last weekend as I was baking my second place award-winning carrot cake, you’d better believe there was a half-teaspoon of salt in that cake. I’m not giving away any secrets here—everybody knows that salt is a difference-maker. It’s absolutely essential and useful. It’s necessary and needed. And that’s you, my friends—the salt of the earth.
You’ve been shaken and scattered here and there to season the world with the good news of Jesus’ death and resurrection. You are the special sodium that makes this fallen world a better place—because you follow Jesus who died and rose again to redeem the whole world. On your head and heart you have received the sign of the holy cross, to mark you as one redeemed by Christ the crucified. For that reason you are destined to make a difference in this world. You are salt.
St. Paul knew what it meant to be the salt of the earth. He knew what his audiences wanted. They wanted miraculous signs and impressive wisdom. But Paul gave them neither. He told the Corinthians: For I decided to know nothing among you. . . except Jesus Christ and Him crucified. You can’t get more salty than that. You can’t season the world in a better way than to give the world Jesus Christ and Him crucified.
We should follow Paul’s salty example. We should season the world with our Savior, not with ourselves. When you draw attention to yourself instead of “Jesus Christ and Him crucified,” you are losing your saltiness. This is especially true here in the church. When pastors and personalities become the center of attention—or when budgets and boards and programs and institutions are the main thing—then the church has lost her saltiness. The death and resurrection of Jesus have taken a back seat to something far less important. Don’t lose your God-given saltiness.
Not only are you salt; you are light—the light of the world. By virtue of your faith in Jesus Christ, you are a light shining in the darkness. Now, your light is like the light of the moon—a reflected light. It doesn’t originate in you; but you reflect Jesus who is the light of the world. You make a critical difference in how this world turns.
Light is visible. Light is noticeable. You can’t miss it. The light you give the world is seen in your good works. Faith is known only to God. Only God can see faith in the heart of a sinner. But the world wants to see your works. In fact, the world needs your good works. That’s why Jesus says: Let your light shine before others, so that they may see your good works and give glory to your Father in heaven. Let your light shine. Let the good works fly—not so that you get the glory, but so that people see the light of Christ in you and give glory to your Father in heaven.
You let your light shine when you do the good works that God has called you to do. You don’t have to be a missionary to Micronesia. Just do what God has put in front of you. Don’t just be a dad—be an all-star dad—an all-star mom. Be the best brother—the best sister a sibling could hope for. Don’t just be an employee—be an excellent employee; not just a citizen—but a super citizen—a great neighbor. Be the difference-maker Jesus has declared you to be. Your good works matter so much.
Sometimes we forget about the importance of our works. We hear a lot about faith alone, and grace alone and Christ alone. The most important teaching in the Christian faith is justification by grace, for Christ’s sake, through faith. There’s nothing about works in there. It teaches how you, a sinner, can be justified before God. And there, works have no role—none whatsoever.
But in the horizontal dimension of faith, good works are everything! Before other people, before family, before friends, neighbors, coworkers and classmates, let your good works shine. God doesn’t need your good works, but those people—they sure do. It’s faith alone before God; but it’s works alone before other people—because in those glorious good works others might just see more clearly your gracious Father in heaven who, in His Son, has reconciled the world to Himself, not counting their trespasses against them.
Your faith in Jesus Christ finds expression in the good works you do for others. You love others because you are loved in God’s beloved Son. You forgive others because all your sins have been forgiven in Christ. You have mercy on others because Jesus Christ has shown mercy to you, and laid down His life as a sacrifice for your sin.
When we don’t love—when we don’t forgive—when we don’t serve and sacrifice for others—we are hiding our light under a basket. We are hiding what Christ is doing in us and through us. And that’s just plain stupid. Let your light shine.
All that you are and have is a gift from Jesus—who is God of God and light of light. Like you, Jesus had a job to do—a job no one else could ever do—one supremely good work. Jesus had to change the trajectory of the world—had to engineer a fourth-quarter comeback from twenty points down. If Jesus fumbled or failed, all would be lost, including you. For us and for our salvation He came down from heaven. For us and for our salvation He became man—was crucified, died and was buried. For us and for our salvation He lived a perfect life of obedience. His righteousness exceeded even that of the Scribes and Pharisees. He was the righteousness of God. He kept the Law of God perfectly—including every last iota.
And wonder of wonders, He gives away that perfect righteousness to you. He gives you the credit for what He did. He makes you the salt of the earth and the light of the world. It’s not by what you do; it’s by what He does—and still does—for you. As you eat and drink His body and blood, He puts His life into your life. You are baptized to live each day beneath the umbrella of God’s grace, through faith in Jesus. And in that grace, you will not fail.
Under that grace you can be the person you have been baptized to be—a person so valuable that God gave up His one and only Son to be crucified in your place, to save you from your sins. Be who you are in Christ. Live as the person you have been baptized to be. Let your light shine so that others can see the Savior and give glory to your Father in heaven.
In the name of the Father and of the Son and of the Holy Spirit. Amen.
