“You are the salt of the earth” (Mt. 5:13).
That statement (“you are the salt of the earth”) not only tells us something about Jesus’ disciples it also tells us something about the world; it implies that the world is rotting. It’s similar to Jesus’ next statement, “You are the light of the world” (Mt. 5:14a), which again, tells us something about His people, as well the world they live in; namely, that the world is in darkness. So if you’ve ever watched the news and thought something like, “This world is going crazy,” not as a manifestation of a ‘holier-than-thou’ mentality but as a kind of ‘knee-jerk reaction’ to either the reported or celebrated sin of men and women, you’d be closer to a biblical worldview that you might have at first realized.
