Sermon on the Mount
The Church as Salt and Light
13 “You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men.
14 “You are the light of the world. A city set on a hill cannot be hidden;15 nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house. 16 Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven.
Jesus instructs us with two metaphors. You are the salt of the earth. You are the light of the world. There is a shade of difference between them, but in both metaphors Jesus reminds the church that we are the hope of the world. We, people of the gospel, transformed by grace, carry a message in our mouths and through our lives that Jesus came to free us from the broken nature of this world.
