13 "You are the salt of the earth; but if salt has lost its taste, how shall its saltness be restored? It is no longer good for anything except to be thrown out and trodden under foot by men. 14 "You are the light of the world. A city set on a hill cannot be hid. 15 Nor do men light a lamp and put it under a bushel, but on a stand, and it gives light to all in the house. 16 Let your light so shine before men, that they may see your good works and give glory to your Father who is in heaven.
Meditation: Jesus used ordinary images, such as salt and light, to convey extraordinary truths. What does salt and light have to teach us about God and his reign on earth? Salt was a valuable commodity in the ancient world. People traded with it, like we trade with gold and stock. Salt also served a very useful purpose in hot climates before the invention of electricity and refrigeration. Salt not only gave food flavor, it also preserved meat from spoiling. Salt was used as a symbol of fellowship and the common meal. The near-Eastern expression to betray the salt meant to betray one's Master or some person who was owed loyalty and devotion. Leonardo da Vinci in his painting of the Last Supper depicts Judas in the act of tipping over the salt shaker, thus symbolically indentifying himself as the betrayer of his Master. Jesus used the image of salt to describe how his disciples are to live in the world. As salt purifies, preserves, and penetrates, so the disciple must be as salt in the world of human society to purify, preserve, and penetrate that society for the kingdom of God and of his righteousness and peace. Why did Jesus speak of discarded salt as being useless? Salt was often put in ovens to intensify the heat. When the salt was burned off and no longer useful it was thrown out on the road or on the roof top where it would easily get trodden upon. Perhaps Jesus wanted to contrast useful salt used for giving flavor and for preserving food with salt which was burned and no longer of much benefit, to encourage his disciples to be faithful witnesses and to not neglect the opportunity to influence others for the kingdom of God through the witness of their lives and their testimony to the power of the kingdom of God. Jesus also used the image of light and a lamp to further his illustration. Lamps in the ancient world served a vital function, much like they do today. They enable people to see and work in the dark and to avoid stumbling. The Jews also understood "light" as an expression of the inner beauty, truth, and goodness of God. In his light we see light ( Psalm 36:9). His word is a lamp that guides our steps (Psalm 119:105). God's grace not only illumines the darkness in our lives, but it also fills us with spiritual light, joy, and peace. Jesus used the image of a lamp to describe how his disciples are to live in the light of his truth and love. Just as natural light illumines the darkness and enables one to see visually, so the light of Christ shines in the hearts of believers and enables us to see the heavenly reality of God's kingdom. In fact, our mission is to be light-bearers of Christ so that others may see the truth of the gospel and be freed from the blindness of sin and deception. Jesus remarks that nothing can remain hidden or secret. We can try to hide things from others, from ourselves, and from God. How tempting to shut our eyes from the consequences of our sinful ways and bad habits, even when we know what those consequences are. And how tempting to hide them form others and even from God. But, nonetheless, everything is known to God who sees all. There is great freedom and joy for those who live in God's light and who seek this truth. Those who listen to God and heed his voice will receive more from him. Do you know the joy and freedom of living in God's light?
"Lord, you guide me by the light of your saving truth. Fill my heart and mind with your light and truth and free me from the blindness of sin and deception that I may see your ways clearly and understand your will for my life. May I radiate your light and truth to others in word and deed".
