The answer is: Salt

Luke 14:34-35

In Luke 14:34-35, Jesus uses the quaint image of salt when discussing the value of discipleship. Salt, which was a key part of the ancient diet and a valuable commodity, serves a dual purpose in this teaching—highlighting both flavor and preservation. But lose its flavor? It’s practically worthless! In the Roman world, salt was so vital that soldiers were sometimes paid with it (hence the term "salary")!

Why is this lesson so profound? Jesus wasn’t just talking about cooking or food preservation; He was pressing into the idea that followers of His teachings should embody the essence of goodness, wisdom, and moral integrity. Just like salt is expected to enhance flavor, people who embrace values should make life richer and wiser for those around them.

Moreover, the use of salt rains true when we consider other biblical contexts. In the Old Testament, salt is often associated with covenant—God commanded that all offerings should be seasoned with salt (Leviticus 2:13). And with a taste of the New Testament, Christians are reminded of being "the salt of the earth" (Matthew 5:13), pushing towards that role of influence and purpose.

So, it's thrilling to think—are we still salty? Success in life sometimes hinges on that subtle seasoning of character and integrity, which can dramatically change the way we engage the world, just like a delicious dish full of flavor.
