13 “You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.
For many centuries salt has been one of the most important commodities in the world. It has been used for preserving foods, for currency, for balancing the blood, for adding taste to foods, and many other things. Our world and our bodies could not function without salt. In fact four-fifths of the world is covered in oceans that are full of salt; it adds to our lives in countless ways.
Jesus used this very important compound to speak of how followers of God need to be engaged in the world around them, while being different from the world. As Christians, this is the directive we need to follow, engaging others by living Christ-like lives, and making a difference in the world around them.
If we fail to be any different from those in the world, then we can no longer represent the difference that Jesus brings into people's lives. We will lose our ability to help bring effective change in people's lives that only belief in Jesus will. He is the Savior of the world, and a person's acceptance of His work on the cross, as payment for personal sins, changes lives.
If you are a follower of Jesus Christ, don't lose your effectiveness by becoming a part of the world and diluting your witness. Instead, stand upon the Rock who is mighty to save, and be living examples of Christ.
