A sin is an act that violates a known moral rule. The term sin may also refer to the state of having committed such a violation. Commonly, the moral code of conduct is decreed by a divine entity, i.e. divine law. Sin may also refer to refraining from action or simply desiring to act in violation of a moral norm. Fundamentally, sin is rebellion against, or resistance to, the direction of supreme authority, and enmity toward, avoidance of, or hatred of the good.[citation needed] Sin may also refer to something within human nature that has a proclivity to sin (see concupiscence)."Sin" is often used to mean an action that is prohibited or considered wrong. In some religions (notably in Christianity), sin can refer not only to physical actions taken, but also to thoughts and internalized motivations and feelings. Colloquially, any thought, word, or act considered immoral, selfish, shameful, harmful, or alienating might be termed "sinful".
