Context is everything! In the sermon on the mount Jesus was explaining the difference in the Kingdom and the world. He constantly admonished the Jews who proudly claimed adherence to Mose's Law. He started with the beatitudes that make no sense in context of this world but establish the truth and grace of Kingdom life. Looking at women with a lustful heart is the same as the act of adultery. Wishing another dead is the same as murder. These things point to the gulf between man and God, the gulf only Jesus could remove by a perfect sacrifice. You've made your laws men and look where they've gotten you. "Come to me all you who are weary and heavy laden....." Some choose not, and endless bickeriing and striving about the law continues. Only Christ followed every "jot and tittle" of the law and if that's the path you choose expect to be judged against that perfection.
