Matthew 5:13-20

13Ye are the salt of the earth: but if the salt have lost its savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out and trodden under foot of men. 14Ye are the light of the world. A city set on a hill cannot be hid. 15Neither do men light a lamp, and put it under the bushel, but on the stand; and it shineth unto all that are in the house. 16Even so let your light shine before men; that they may see your good works, and glorify your Father who is in heaven.

17Think not that I came to destroy the law or the prophets: I came not to destroy, but to fulfil. 18For verily I say unto you, Till heaven and earth pass away, one jot or one tittle shall in no wise pass away from the law, till all things be accomplished. 19Whosoever therefore shall break one of these least commandments, and shall teach men so, shall be called least in the kingdom of heaven: but whosoever shall do and teach them, he shall be called great in the kingdom of heaven. 20For I say unto you, that except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no wise enter into the kingdom of heaven.
