You are the salt of the earth; but if the salt has lost its savor, how shall it’s saltiness be restored?
To be the salt of the earth means we embrace the wisdom of the cross. The cross is contrary to the wisdom of the world, however. Salt is a preservative and the worldly wise seek self preservation. But to be the salt of the earth according to the gospel means self denial. The cross shows us the way of love and how we can preserve the world with God’s savor—the wisdom of the cross.
