Natural Law and Man's Law or the Legal System are NOT the same. They can be aligned (theoretically) or differ (massively) - it's a whole spectrum! Natural Law: Based upon principles & truth inherent to creation. It is up to your free choice to harmonize with it through knowledge of it and its understanding. It is universal; it exists and applies anywhere regardless of locations, also it is eternal and immutable. It exists and applies for as long as the universe exists, and cannot be changed. Also termed negative rights or natural rights. Man's law / Legal: Mostly based upon dogmatic beliefs which are constructs of the mind. It is complied with, mostly not by free choice but due to fear of punishment. It differs with location and changes with time based upon the whim of legislators. Thats called Moral Relativism. Also termed positive rights or legal rights.
