March 24 Salt and Light—the Nature of Believers

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. You are the light of the world. A city set on a hill cannot be hidden; 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. 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.—Matt. 5:13–16

In these four verses the Lord summarizes the function of believers in the world—influence. This is a mandate for Christians to influence the world. The Beatitudes are not to be lived in isolation or only among fellow believers, but everywhere we go.

In verses 13 and 14, the pronoun “you” is emphatic. The idea is, “You are the only salt the earth knows and the only light the world sees.” The world’s corruption won’t be retarded and its darkness won’t be illumined unless God’s people are its salt and light. “You” in both verses is plural; that means the whole body, the church, is called to be the world’s salt and light.

By definition, an influence must be different from that which it influences, and Christians must be different from the world they are called to influence. We cannot influence the world for God if we are worldly ourselves, nor can we give light to it if we retreat to places and ways of darkness ourselves.

ASK YOURSELF

Is there anything that’s currently taking the bite out of your saltiness, or dimming the brightness of your light? Deal openly with the Lord about these things, asking Him to rid you of their influence so that you can be used of God to influence others.[1]
