Matthew 5:13-16 New International Version (NIV)
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.
Isaiah 58:9-14 New International Version (NIV)
9 Then you will call, and the Lord will answer;
you will cry for help, and he will say: Here am I.
“If you do away with the yoke of oppression,
with the pointing finger and malicious talk,
10 and if you spend yourselves in behalf of the hungry
and satisfy the needs of the oppressed,
then your light will rise in the darkness,
and your night will become like the noonday.
11 The Lord will guide you always;
he will satisfy your needs in a sun-scorched land
and will strengthen your frame.
You will be like a well-watered garden,
like a spring whose waters never fail.
12 Your people will rebuild the ancient ruins
and will raise up the age-old foundations;
you will be called Repairer of Broken Walls,
Restorer of Streets with Dwellings.
13 “If you keep your feet from breaking the Sabbath
and from doing as you please on my holy day,
if you call the Sabbath a delight
and the Lord’s holy day honorable,
and if you honor it by not going your own way
and not doing as you please or speaking idle words,
14 then you will find your joy in the Lord,
and I will cause you to ride in triumph on the heights of the land
and to feast on the inheritance of your father Jacob.”
For the mouth of the Lord has spoken.
