Mateus 5

13 You are the salt of the earth. If the salt become insipid, how shall its saltness be restored? It is thenceforth fit only to be cast out, and trod under foot.

14 You are the light of the world. A city situate on a mountain must be conspicuous.

15 A lamp is lighted to be put, not under a vessel, but on a stand, that it may shine to all the family.

16 Thus, let your light shine before men, that they, seeing your good actions, may glorify your Father, who is in heaven.
