The Ten Commandments: Why the Law?
Perhaps the first and most basic question needing addressed is, why the law? After all, this question is raised in both Galatians and Romans. However, it is preceded by another question. Paul asked the Galatians, does the law given to Moses nullify the promise given to Abraham? Let me illustrate what Paul is asking. If I promise to give my car to a friend next week, then I have made him a promise. However, when the week arrives for me to give my friend my care and I say, “You can now have my car if you do these three things,” what have I done? I have introduced a law that nullified my promise. So, has the law given to Moses nullified the promise given to Abraham? The answer is clear. No, the law does not make void the promise (Gal. 3:17-18).
