Matthew 5:13-20
5:13 "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.
5:14 "You are the light of the world. A city built on a hill cannot be hid.
5:15 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.
5:16 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.
5:17 "Do not think that I have come to abolish the law or the prophets; I have come not to abolish but to fulfill.
5:18 For truly I tell you, until heaven and earth pass away, not one letter, not one stroke of a letter, will pass from the law until all is accomplished.
5:19 Therefore, whoever breaks one of the least of these commandments, and teaches others to do the same, will be called least in the kingdom of heaven; but whoever does them and teaches them will be called great in the kingdom of heaven.
5:20 For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven."
