According to the Word, this saying has a completely different meaning than you might think. The Word tells us to go out and be the salt and the light of the world…
Matthew 5:13-16
Salt and Light
13 “You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.
14 “You are the light of the world. A town built on a hill cannot be hidden. 15 Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. 16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
Go out into the world and shine…be the light in those lives around you!
