Mankind recognizes that laws made by legitimate earthly governments are binding. Yes, but they also recognize that some laws made by legitimate earthly governments are not binding but are unlawful in themselves. The German government under Nazism would be an example of this.
That government stipulated many laws. However, later, during war crime trials judges that enacted and enforced some of these laws were found guilty of wrong doing. But these judges were the supreme judges of Germany at the time. How could they, since they possessed
legitimate authority to do so, have been found guilty of committing crimes against humanity?
When men make laws are not the laws they make always right and always good?
Obviously this was not the case in Nazi Germany. And if it was not the case there, then it means that just because governments enact laws and enforce laws the laws they stipulate are not necessarily righteous or good laws all by themselves. Even for lawmakers there can be violation of law by the laws made.
How could a lawmaker violate law by making a law? How could this be possible?
The answer can only be that some laws are immoral because a righteous and just law is not made solely by declaring it. This means there is a higher law or a higher standard of law that all laws made by earthly governments are accountable to uphold. Even if the nations refuse to admit it the ultimate standard when it comes to law is God. And the Bible is His law book that lays down the laws of that perfect standard of righteousness.
