Light transforms how we see. Light warms us when we are cold. You are the light of the world. Your goodness must exceed the goodness of the Pharisees and scribes. Don't just be good.
Salt is an amazing substance.
A little bit goes a long way and can transform the taste of food. My stepmother has a penchant for finding bargains. One time she made a special purchase of dietetic cheese. It was natural cheese, that through some process, had all the salt removed. Salt absolutely transforms some of our food.
