Answer:
Natural law refers to moral principles common to most or all human cultures. Divine law is not univerally known, though it may be universally binding. If you do not believe in God, then you will not find divine law compelling, or even, really, acknowledge its existence.
Divine law is mainly and mostly natural law, but it can also be positive law. Natural law is a theory in ethics and philosophy that says that human beings possess intrinsic values that govern our reasoning and behavior. Natural law maintains that these rules of right and wrong are inherent in people and are not created by society or court judges.
