It even seems to stand outside of us condemning or condoning our thoughts, desires, words and actions. Paul says that all men and women, Christians or not, have this Law of God written on their hearts. We are created as moral beings. Not only is right and wrong knowable, but it is actually part of who we are. Sinful hearts turn away from and miss-apply and do not always understand God's Law nor their consciences.
Scripture is the tool that brings it into focus.
But its existence in the heart of every person is undeniable. Our society at large acknowledges this. There can be no doubt that humans are indeed moral creatures. But the Christian view of the self does not teach that this is merely a hope to do right and an ability to design and decide what good and evil will be. But, that in our very nature and created state we are imprinted with the moral code given by our creator.
