If you don't remember what Jesus has been talking about, it's easy to miss what he really means by salt and light. In this passage, Jesus calls his disciples to be, like him, salt in a world that hates the flavor, and light in a world that loves the dark. If that sounds tough, it's because it is. But if it sounds hopeless, don't despair. Jesus says that his salt-and-light disciples not only offend the world, but also transform it. That's what he himself did. He was a light in a world that loved the darkness so much that it tried to put out the light by putting him to death. But now, risen from the dead, he is giving life to that same world.
