Upon their return, his Sunday School teacher asked what he liked most about the great churches of Europe. His Sunday School teacher then asked what was his definition of a saint. This young boy picked up an eternal truth when he used the picture of the Light of God shining through the lives of God's people. In today's passage, Jesus combines the images of light, salt and a city set on a hill to describe the character of the Christian. Each of the things Jesus mentions brings a certain uniqueness to life.
Salt brings a very distinctive flavor to food.
It helps bring out the natural flavor of vegetables. It enhances and livens up food. There is no mistaking it when the cook accidentally leaves out the required amount of salt. Hospital patients are sometimes put on a low salt diet, and most people experience the loss of the salt-flavoring as a huge sacrifice. Food loses its zest without salt.
