Matthew 5:13-20
At the beginning of worship:
Did you hear about the guy pulled over by police? The officer asked if it was his car. He said yes. Then the officer had him step out of the car and put his hands on the hood. He handcuffed the man and hauled into the station on suspicion of stealing a car. Yet, the man kept insisting it was his car. The officer put him into the holding tank and, taking his license and registration, began to check out his story.
Thirty minutes later, the officer released the man and apologized. “I couldn’t believe it was your car,” the officer said. “You have all those bumper stickers about loving Jesus and and following you to church. When I saw you give the finger and heard you shouting obscenities and lay on your horn at that poor driver who was obviously lost, I just assumed you stole the vehicle.”
You know, actions speak louder than words. If we’re a follower of Jesus, we need to remember this.
Before reading the scriptures:
The last two weeks, we looked at the beatitudes, which make up the beginning of the Sermon on the Mount.[1] I hope you read or watched those sermons on-line as we had to canceled in person worship due to ice and snow. Today, we’re heading into the middle portion of the Jesus’ sermon.
Jesus begins with two emphatic statements directed at his audience. You are the salt and the light of the world. But these statements are not to be taken individually. The “You” used here is plural. If Jesus gave this sermon here, he’d say, “Y’all.” It’s all of us. Those who believe and accept Jesus, in other words, the church, are the salt and the light of the world.[2] We’ll look at what that means. Next, Jesus teaches about his relationship with Scripture and the Covenant.
Let’s look at what Jesus has to say here.
Read Matthew 5:13-20
What does it mean to be the salt and the light of the world today? You know, salt is important. We tend to take it for granted, except for the past few weeks with ice everywhere, stores quickly sold out of salt.
In the ancient world, salt was even more valuable and harder to come by than today during an ice storm. It preserved food and likewise, we’re to help preserve the world. When used sparingly in cooking, it helps enhance the flavor. We’re to flavor the world with Jesus’ grace. And, in a world without modern medicine, they applied salt to wounds to assist in healing. We’re to help heal the world.
Oddly, as a friend wrote on this passage, we’re the first generation to be paranoid about our use of salt.[3] Too much of it, we know, causes hypertension and other health problems. But we must have some, or we have other issues. Salt is the only mineral we take straight from the earth and consume. So, when Jesus said the church is the salt of the earth, he wants us to spice the world up, to help preserve the world, and to help heal it.
In a way, light is like salt. Compared to light in the ancient world, it’s cheap. We have light everywhere. Sometimes we have so much light it becomes a determent of our ability to see things like the stars. Thankfully, we live where the skies are dark and the stars shine brightly, but that’s not the case if you live in an urban area. In a world without electricity and bright LEDs, when the sun wasn’t up or the moon down, you appreciated light. The only light came from campfires, or candles, or oil lamps. Each of these have a limit as to how far you could see before you slipped back into darkness.
When I lived in Utah, I drove across central Nevada several times at night. I took highway 50, which Life Magazine claimed back in the 1950s to be the loneliest road in America. The other path was a combination of US 6 and Nevada 375, which is even a lonelier road, as you seldom saw a car at night.[4]
Cutting across the state, you crossed many block-fault mountains which run north and south. Coming off the summits, you’d often see your next town, just a few lights clustered together, way off in the distance. The next sign of civilization, far away. If you needed gas, you’d hope that within the oasis of light a gas station remained open. Or if you didn’t need gas, you’d hope there was a place for coffee to keep you away. As for gas, I always tried to keep my tank above the halfway mark.
As the church, we’re to be light helping guide the world. Maybe a better metaphor would be navigation lights which help boaters travel narrow waterways and inlets. In the daytime, you have buoys, but at night the buoys have colored lights on them. Remember the three R’s of navigation: red, right, returning. If you are coming into an inlet at night, you keep the red lights or buoys on your right or starboard side. The green ones go on your left or port side. As a church, as the light in the world, we guide people to Jesus, just as navigation lights guide people safely through an inlet.
Both opening metaphors apply to how we live. Do we point the way to Jesus, or do we get so tied up in the world’s business and lose focus on what’s important? Interestingly, Jesus doesn’t tell us to become the salt or the light of the world. Nor does he tell us to become salter or shine brighter. Instead, he grants us these abilities. But there’s a warning here. If we squander these gifts, if we fail to use them for Jesus’ purposes, for God’s glory, we become worthless. Salt without flavor or a light hidden is of no use for the world. But if we use them properly, others can see through our efforts, God’s glory.
Our next section deals with the purpose of Jesus’ ministry. Why did Jesus come? Was it to negate what God has been doing through Israel for the past 15 or 20 centuries? No, there’s still value in that work.
When Jesus speaks of the Law and the Prophets, he’s referring to the entirety of the Hebrew Scriptures or what we call the Old Testament. Some Christians may attempt to ignore the Old Testament, but that’s not Jesus’ way. He values scripture and regularly quotes or alludes to passages from the Psalms and other books of the Hebrew Bible, especially Genesis and Isaiah.
By linking the Law and the Prophets together, Jesus refers to a new covenant. The first covenant of the Hebrew people was established with Abraham, Isaac, and Jacob and renewed with Moses and Joshua and the Hebrew people. But in the latter part of Isaiah, God through the prophet speaks of a new covenant, one where Israel is to be the light to the nations.[5] The old covenant has been fulfilled, this new covenant will extend beyond the ethnicity of the Jews to all people.
As I have pointed out repeatedly as we’ve gone through the opening chapters of Matthew, this gospel is most concern with Jesus’ message going out into the world. We see that in the beginning with the foreign wisemen coming to Jesus and at the end of the gospel with Jesus sending the disciples out to all corners of the earth.
What might we learn from this passage? While much of Jesus’ Sermon on the Mount deals with our interior lives as we saw with the Beatitudes and will observe in the weeks ahead, we also see the importance of living in a manner which honors God. Once Jesus ascended to heaven after the resurrection, he left behind a church to do his work. That’s us. We’re to live in such a manner that people will want to be like us. As the old spiritual goes, “They’ll know we are Christians by our love.” Will they? Amen.
