Jesus commanded Christians to be “the salt of the earth” and “the light of the world” (Matthew 5:13-16). The second part of that calling—to be the “light of the world”—tends to make more sense to us. We know how necessary light is where there isn’t any. It is easy for us to translate that into our need to be light in order to dispel gloom (and there is no shortage of that!).
The first part, though, doesn’t resonate so well. Salt? Really?
