“Salt is good, but if salt has lost its taste, how shall its saltiness be restored? It is of no use either for the soil or for the manure pile. It is thrown away. He who has ears to hear, let him hear.” Luke 14:34-35
Salt seems relatively unimportant to us today; it is nothing more than something added to food to enhance its flavor. For the ancients, however, salt was much more than this; it was a precious commodity. In many cultures, this mineral was worth its weight in gold. In an era before refrigeration and medical advancements like antibacterial medications, salt was a wonder mineral that could do nearly everything.
One characteristic of salt that made it so valuable is that it has the unique ability to preserve meats and foods from spoiling. This is the result of the mineral drawing moisture out of the food to which it is being applied. Additionally, salt also has the ability to purify things to which it is applied, and this also aids in its preservation. The salt kills any bacteria which would cause the food to rot or spoil quickly. Salt removes impurities and preserves that which is worth saving. It removes the bad and preserves the good.
As valuable as salt was to the ancients, though, it was useless once it lost its “saltiness”—those characteristics which enabled it to do the numerous things it did. Once the salt became not “salty,” there was nothing which could make it salty again. It could not be thrown into the fields, because too much salt in the soil would ruin the soil and prohibit and future growth. In this regard, even manure was better than saltless salt, because manure had a use as fertilizer. In Matthew’s gospel, Christ says the only use for salt that has lost its saltiness is to be thrown out upon the roadways and trampled under the feet of people. In other words, it was useless and good for nothing–it had lost the qualities which made it such a precious commodity.
Christ compares those who follow Him—His disciples—to salt. The authentic follower of Christ–one who follows the hard teachings of daily taking up one’s cross, loving Christ more than their family or their lives, seeking to embody the qualities of humility and total reliance upon God depicted in the Beatitudes–acts as salt in this world; they purify and preserve. The true disciple preaches out against sin and seeks to teach others how to be rid of the their sins by submitting to Christ and being washed in His blood. Along with this, the disciple of Christ builds up fellow believers, seeking fellowship and further discipleship. In these ways, the disciple purifies and preserves, just as salt did.
We must recognize that there is nothing in us innately which empowers us to be “salty;” it is only through the indwelling of God’s spirit within us that we can be the salt of the world. Furthermore, we must remember that we must abide in Him to continue being “salty.” When we lose sight of either of these facts–when we begin seeking our glory instead of His, or when we think that it is our talent and strength that is changing people–we lose our saltiness. When we neglect our duty as disciples of Christ–to preach and teach and make new disciples–we lose our saltiness. When we sit back and not speak out against the sin that is so rampant in the world, and we do not build up our brothers and sisters in the faith–when we do not purify and preserve–we lose our saltiness. Remember what salt is good for once it has lost its saltiness–nothing.
Christ made it clear: you can’t be a neutral disciple. You can’t be a nominal follower of His. You are either salt, or you are not. You are either good for something, or you are good for nothing. You are either purifying and preserving, or you are being trampled underfoot by the world. The choice is yours. Be salty.
