Jesus often addressed things in a pattern of "precept (law/rule), principle, action." Have you ever thought about adultery and how bad it is? Look how Jesus addresses it:
Precept: Mat 5:27 "You have heard that it was said, 'You shall not commit adultery."
Principle: Mat 5:28 "But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart."
Action: Mat 5:29 "If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell."
Can you notice other times that Jesus uses this "precept, principle, action," method of addressing issues? They're always perfect solutions!
