Jesus said, “You people that follow me are like salt for everybody on the earth. You know, salt helps food taste good and stops it getting bad. Well, if you follow me properly you will live in a way that helps people to be good. Yes, salt is good, but if it stops tasting like salt it is no good any more. Nobody can use it for anything. They chuck it away and everyone walks on it. So don’t you be like that kind of salt. Don’t stop following me.”
