A Covenant of Salt is mentioned only three times in Scripture:
Leviticus 2:13 – “And every offering of your grain offering you shall season with salt; you shall not allow the Salt of the Covenant of your God to be lacking from your grain offering. With all your offerings you shall offer salt.”
God used the term again in Numbers 18:19 when talking about what part of the offering the Levites were to use for their provision of food. “Whatever is set aside from the holy offerings the Israelites present to the LORD I give to you and your sons and daughters as your regular share. It is an everlasting Covenant of Salt before the LORD for both you and your offspring.” Eventually, people began to make a connection between an offering to God, salt, a meal, and the making of a covenant.
2 Chronicles 13:5 reinforces this. “Don’t you know that the LORD, the God of Israel, has given the kingship of Israel to David and his descendants forever by a Covenant of Salt?”
When we want to stress a person’s worth we often say that he or she is the salt of the earth. In the ancient world, salt was highly valued. The Christian’s task is to be the salt of society, preserving, reconciling, adding taste, giving meaning where there is no meaning, giving hope where there is no hope.
Salt is a number of effects :
Seasoning Agent…as a seasoning agent, it improves the taste of the food that it comes into contact with. The person who sacrifices their life for someone else’s, a person who gives of their time to help another, etc..so as we come into contact with society our Christian values should also improve the nature of that society.
Thirst…salt makes people thirsty – As Christians we seek to create a thirst in people’s lives that can only be satisfied by Yeshua, who said : “if anyone is thirsty, let him come to me and drink” You may not be able to make a horse drink, but you can add salt to its oats, and thereby make it thirst for water! Indeed the same effect is produced when one person see’s the effect of GOD on another’s life…they thirst for real “LIFE”.
Warming Effect…Salt is used to thaw ice on roads. Here we can see the effect of warming hearts that have hardened against the gospel. It’s amazing the transformation and changes that being a believer has on someone. But to truly put GOD in your life and make HIM first, changes your very soul. Over time the saltiness of Christians can bring people to know Yeshua.
Preservative…as a preservative. Salt is used to maintain the length of time in which meat can be used. In ancient days, there were no refrigerated areas to maintain the temperature of meat as to not go bad, so salt was added to lengthen the time frame in which meat can be eaten. Ultimately, with enough salt, those who do know Yeshua, and acknowledge Him as Lord and Savior will have eternal life.
