Matthew 5: 13 You are the salt of the earth, but if salt has lost its taste (its strength, its quality), how can its saltness be restored? It is not good for anything any longer but to be thrown out and trodden underfoot by men. (AMP)
What is salt? What is it good for—used for? When you put it on food, doesn’t it enhance the flavor? Bring out a stronger, more savory taste? Make it better? If you have a rock-salt water filter, isn’t the purpose to remove the impurities, and improve the water?
2 Kings 2: 20 Elisha said, “Bring me a new bowl with salt in it.” So they brought it to him. 21 Then he went out to the spring that supplied the town with water and threw the salt into it. And he said, “This is what the Lord says: I have purified this water. It will no longer cause death or infertility [make the land unproductive].” 22 And the water has remained pure ever since, just as Elisha said. (NLT)
What is Jesus saying to us in calling us the ‘salt of the earth’? Aren’t we, in fact, being asked to enhance? Make stronger? Make better? Remove impurities and improve (both ourselves and those around us)?
Mark 9: 49 For everyone shall be salted with fire. 50a Salt is good (beneficial), but if salt has lost its saltness, how will you restore [the saltness to] it? (AMP)
And what does He mean in pointing up how difficult it is to restore our ‘saltness’ if it be lost? Isn’t salt without its ‘saltness’ just a dusty, bland rock; brittle and easily crumbled under pressure?
Mark 9: 50b Have salt within yourselves, and be at peace and live in harmony with one another. (AMP)
