Towards the beginning of the Sermon on the Mount, Jesus uses a couple of familiar metaphors: He says to his disciples, "You are the salt of the earth," and, "You are the light of the world." Both indicate that Christians are "for" others, as salt and light are not so much good in and of themselves but rather essential for the effect that they have on others. Regarding the former image, let us consider how the Lord is inviting us to be "salt" in the various arenas of our lives, that, like salt, we may enhance and elevate and make more authentic the diverse areas of life: precisely the effect that Jesus demands that his followers have on the world.
