We are a nation of laws. These laws provide an agreed upon framework for our society to function and prosper. They allow us a safe and stable environment to build and create. Over the past 200 years we have created more than 23,000 pages of laws. Of course, some of these laws grow useless over time and need to be changed or discarded.
Natural and moral laws, on the other hand, were not created by mankind. These laws are immutable and we run into some real issues when we attempt to change or discard them.
But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.
Genesis 4:5 KJV
