Read: Numbers 30-31, Mark 9:30-50

Little Manitou Lake in Saskatchewan has a mineral density three-times that of the oceans. Who cares? Well, what this means is that, unless you intentionally put your head under water and breathe in, you can’t drown. The water is so dense, a human being can float with no effort at all. The high mineral—salt—concentration in the lake (and spa where the lake water is piped in) has disinfectant and healing properties. It is only one of three inland bodies of water on the planet that has such properties (the Dead Sea being another). It’s rare. It’s special. It’s worth taking note.

Many of us might read through this little verse and just assume that Jesus wants us to be flavourful, add a little spice to the world around us. That’s what salt is for, after all. And that little part about being at peace with each other, just a nice little add-on. The complexity and weight of this verse is completely lost on us if we don’t understand the cultural connotations of salt at the time Jesus said these words.

1. Salt was valuable. When you start a new job you settle on what? A salary. Ever wonder where that word originated from? You’d better be worth your salt or you won’t be keeping that job. Some speculate that, because of it’s high value in the Roman empire, that soldiers were often paid in salt. Roads were built because of salt. Trades were made because of salt. Lives were made or lost because of salt.
2. Salt healed. Like patrons of Little Lake Manitou, the Romans were also aware of the healing properties of salt. Drinking a saltwater solution could reset the digestive system. Soaking an open wound in saline could help prevent swelling and infection.
3. Salt preserved. While the term pickled didn’t arrive on the scene for centuries, the concept of preserving food with salt was not lost on the Roman empire. Salty olives were as much a part of the Mediterranean diet then as they are now.
4. Salt was considered holy. Since Leviticus 2:13, salt was a part of Jewish sacrificial offerings. No sacrifice was to be made without it.
5. Salt declared covenant. In both Jewish and Roman cultures, sharing salt at a table was indicative of covenant or servitude. For the Romans, to eat salt from the table of another put you in their service. For the Jews, to share bread with salt was a sign of covenant between those who share the meal.

When we take into account the historical significance of salt, this verse is so much more than a little platitude for us to remember. Whether in food or water, the presence of salt is undeniable. Imagine a society without salt. Imagine your life without salt? It’s impossible. As trivial as those little granules may seem, they are an essential part of our lives.

Now take that idea and apply it to believers.

Everything that salt was to society when Jesus walked this planet, we should still be to our culture today. Believers should add value, no matter where we are. We should bring healing. We should preserve those things that are good and helpful and nourishing to every life. We should be set apart as holy. And we should share a covenant not only with God, but with each other. Our lives should be set apart for service to the Father and to our brothers and sisters in Christ.

Suddenly this verse isn’t so little and that last bit about being at peace with each other means a little more.

Are you worth your salt?
