Law is a set of rules that a society or government develops in order to deal with crime, business agreements, and social relationships. It has been variously described as a science and an art. It is a central part of the societal fabric, and many people study it to become lawyers or other legal professionals. There is a wide variety of legal systems around the world, some of which are based on civil law, others on natural or canon law, and still others on Islamic or Jewish law.
There are also different areas of the law, such as family law, criminal law, property law, and corporate law. In the United States there is a large variety of state and federal laws that can be applied to different situations. Some are general, such as traffic law, and some are specific, such as the rules for a particular type of case, such as murder.
The term law can also be used to refer to a person or organization that enforces the law: the police; the justice system; the courts; and the constitution. The term is sometimes used in a more general way to refer to any rule or principle of conduct sanctioned by conscience, concepts of natural justice, or the will of a deity: a moral law.
It is important to remember that the primary function of law is to establish order and stability in a given jurisdiction. This can be difficult in a country with many ethnicities, religions, and social classes; and there are often protests or even revolutions that seek to change the political-legal structure of a nation.
In the Bible the word law (nomos) is primarily associated with Mosaic scripture, where it is a direct reference to God’s commands and regulations for his people. In the New Testament, there are a number of references to the teachings and principles that Jesus and his disciples upheld, which can be linked with the idea of law in a more general sense.
In addition to establishing order and stability, the law is also supposed to be equitable and impartial in its application to individuals. This is a challenge because people are different and some have greater resources or status than other citizens. It is also hard to maintain a balance between liberty and protection of the innocent. Nonetheless, the rule of law is essential to civilization.
