“You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again?” Matthew 5:13
This is not the first outrageous thing that Jesus says in the Sermon. It is, however, pretty out there. This statement may be the first that stuns us. Within this verse lays the point of the Sermon. In telling us that we are the Salt of the Earth. It sums up who we are and prepares us for the instruction that is to follow.
“Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah. Jeremiah 31:31
Within the Sermon Jesus is revealing the new covenant.
The most common comment pertaining to Jesus telling us that we are the salt of the earth is that the other people have it wrong. Of course the author of the commentary, the commentator, has the correct understanding. It seems terribly Christian.
Briefly, there are references to seasoning, to purifying, to preserving, to fertilizing, and I am sure there are more. In almost every commentary the writer picks one and describes how that is what Jesus meant. I actually kind of like the wide and varied range of interpretations of this verse. And me, being me, will wade into the discussion as well.
There is another reference to salt that comes from the Old Testament that seems to make more sense. At least to me. It also seems more appropriate to the intent of the Sermon on the Mount. That is, we are the salt of the covenant. Of the New Covenant.
In the Ancient Near East, the geography of the Bible, salt was believed to be extremely valuable for sustaining life. In many cultures it was believed to be the vital substance within blood. Thus, a covenant of salt was a cultural practice in the ancient world that signified an oath or a covenant. Think a blood oath. One party would form a covenant by eating the salt of the other. The party of greater power and authority, God in this case, would provide the salt.
The imagery of the Sermon of the Mount references Moses and his receiving the covenant on Mt. Sinai. I would write that it is obvious imagery, but that reference did not dawn on me for a number of years. (But then again, I can miss the most obvious.) Just as Moses received the Ten Commandments on a mountain, the followers of Jesus were receiving instructions on a mountain.
They were seeing a new covenant being established. They were the salt of the covenant. We are the salt of the covenant.
My Pastor teaches that in the Sermon on the Mount that Jesus starts with teaching us that we are valuable. Salt, regardless of what one might think it was used for, was valuable. That is a repeated message throughout all the Gospels. We prodigal children, lost sheep, lost coins. Heaven rejoices as we are brought back into relationship with God. We are loved and valued.
But this is where my idea of us being the salt of the new covenant makes sense. Our value is not only in being brought back into right relationship with God. It is that we, being the salt of the new covenant bring, bring the message of this covenant into the world. We are the testament to God’s love for us. Not just some of us. All of us.
We are living testaments to this new covenant. We let people know that God loves us and desires to be in relationship with him. We. Us with all our foibles and follies. We are witnesses that we do not have to get our act together in order to come to God. As the author of Hebrews states, “Let us then approach God’s throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.” (Hebrews 4:16)
Consider those to whom the Sermon was first preached. As Tim Mackie says, “They were the zeros of their time.” The were those who felt broken and defeated in the world. They were those who longed for righteousness. They were those who grieved the condition of the world and of themselves.
Our confidence does not, cannot, lay with the efforts we make. Trust me, I am probably for fallible that most. Our confidence lays within the love and grace of God. Whatever you understand about Christ’s sacrifice, what is clear is that our path to God is made open by his love.
