Recently I was sentenced by my doctor to 18 days without any salt in my diet. I discovered it was like working in a salt mine but not being able to have any salt. It was a blessing in disguise however, because it radically opened my eyes to what Jesus was talking about when He called His followers to be the salt of the earth. (Matthew 5:13)
Salt is used primarily for two reasons — to add flavor and as a preservative. Every grocery store and restaurant would have difficulty surviving without it because it makes what they sell tasty –and even more importantly as a preservative it extends the shelf life of their products.
As never before, my diet helped me realize that as sodium extends the life of a perishable, how much more are we, as followers of Jesus, to be the salt of the world to extend the perishable lives of people into imperishable eternity. (1 Corinthians 15:53-54
