Salt and Light

"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 by men.
"You are the light of the world. A city on a hill cannot be hidden. 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. In the same way, let your light shine before men, that they may see your good deeds and praise your Father in heaven."
Matthew 5:13-16

"You have heard that it was said to the people long ago, 'Do not murder, and anyone who murders will be subject to judgement.' But I tell you that anyone who is angry with his brother will be subject to judgement. Again, anyone who says something in contempt to his brother is answerable to the Sanhedrin. But anyone who says, 'You fool!' will be in danger of the fire of hell.
"Therefore, if you are offering your gift at the alter and there remember that your brother has something against you, leave your gift there in front of the alter. First go and be reconciled to your brother; then come and offer your gift.
"Settle matters quickly with your adversary who is taking you to court. Do it while you are still with him on the way, or he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison. I tell you the truth, you will not get out until you have paid the last penny."
Matthew 5:21-26

"You have heard that is was said, 'Do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already commited adultery with her in his heart. If your right eye causes you to sin, gouge it out and throw it away. It is better for you to lose one part of your body than for you whole body to be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell."
Matthew 5:27-30

"It has been said, 'Anyone who divorces his wife must giver her a certificate of divorce.' But I tell you that anyone who divorces his wife, except for marital unfaithfulness, causes her to become an adulteress, and anyone who marries the divorced woman commits adultery."
Matthew 5:31-32
