Matthew 5:17-29: 17"Do not think that I have come to abolish the law or the prophets; I have come not to abolish but to fulfill. 18For 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. 19Therefore, 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. 20For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.
21"You have heard that it was said to those of ancient times, 'You shall not murder'; and 'whoever murders shall be liable to judgment.' 22But I say to you that if you are angry with a brother or sister, you will be liable to judgment; and if you insult a brother or sister, you will be liable to the council; and if you say, 'You fool,' you will be liable to the hell of fire. 23So when you are offering your gift at the altar, if you remember that your brother or sister has something against you, 24leave your gift there before the altar and go; first be reconciled to your brother or sister, and then come and offer your gift. 25Come to terms quickly with your accuser while you are on the way to court with him, or your accuser may hand you over to the judge, and the judge to the guard, and you will be thrown into prison. 26Truly I tell you, you will never get out until you have paid the last penny.
27"You have heard that it was said, 'You shall not commit adultery.' 28But I say to you that everyone who looks at a woman with lust has already committed adultery with her in his heart. 29If your right eye causes you to sin, tear it out and throw it away; it is better for you to lose one of your members than for your whole body to be thrown into hell.
