11 Take care that you do not forget the Lord your God, by failing to keep his commandments, his ordinances, and his statutes, which I am commanding you today. 12 When you have eaten your fill and have built fine houses and live in them, 13 and when your herds and flocks have multiplied, and your silver and gold is multiplied, and all that you have is multiplied, 14 then do not exalt yourself, forgetting the Lord your God, who brought you out of the land of Egypt, out of the house of slavery, 15 who led you through the great and terrible wilderness, an arid wasteland with poisonous snakes and scorpions. He made water flow for you from flint rock, 16 and fed you in the wilderness with manna that your ancestors did not know, to humble you and to test you, and in the end to do you good. (Deuteronomy 8:7-16)
13 “You are the salt of the earth; but if salt has lost its taste, how can its saltiness be restored? It is no longer good for anything, but is thrown out and trampled under foot.
14 “You are the light of the world. A city built on a hill cannot be hid. 15 No one after lighting a lamp puts it under the bushel basket, but on the lampstand, and it gives light to all in the house. 16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father in heaven.
(Matthew 5:13-16 )
