I began to question this theory of the Moral Law when I realized what Lewis was arguing against in this piece. He argues against teaching a separate and different set of values to children. However, this in and of itself implies that these values must be taught or else they become lost. Isn't the Moral Law "written on our hearts"? How can we lose something such as this? If we must be taught to disobey, are we not also then taught to obey?
When searching for an answer, I turned to my own life for help. I was taught right and wrong by my parents (or at least that is what I think). They presumably also learned from their parents, teachers, and experiences. Where did this idea of right and wrong come from? In my case, my parents believed the Bible and taught its words as a "moral law." Where did the laws of the Bible come from? They came from God. But what about other cultures? Does this same reasoning apply? Children being taught by parents is certainly the case worldwide. However, the source of those values may take a different form, such as a Muslim using the Koran. Yet in most core beliefs, such as the right of a person to live, all cultures agree. This leaves us with two options. Either God has given us his Law, a Moral Law, in our hearts and therefore also in the hearts of the people writing other "holy" books, or God inspired the "holy" books of other religions as well. Since Christianity calls for One Way, One Truth, and One Life, the second option cannot be correct.
This leads me to believe in the Moral Law, but there are other unanswered questions that I still must deal with as well. At least for now, I can agree with Lewis when he says that this Moral Law must still be kept in a place of honor.
