C. S. Lewis wrote a book entitled The Joyful Christian. It consists of 127 readings, and several relate to my own writings, which I will share on my blog with comments. The first is from his reading “Right and Wrong.”
“Now this Law or Rule about Right and Wrong used to be called the Law of Nature. Nowadays, when we talk of the ‘laws of nature,’ we usually mean things like gravitation, or heredity, or the laws of chemistry. But when the older thinkers called the Law of Right and Wrong ‘the Law of Nature,’ they really meant the Law of Human Nature. The idea was that, just as all bodies are governed by the law of gravitation and organisms by biological laws, so the creature called man also had his law - with this great difference, that a body could choose either to obey the Law of Human Nature or to disobey it.”
Believers have been blessed by the love and grace of God through the sin sacrifice of the living Jesus Christ to have the indwelling of the Holy Spirit restored. The Spirit of God serves as Counselor and Helper, guiding our choices in life and discerning right and wrong. But as Lewis states, we have also been given free will and can choose to obey or to disobey the Law of Right and Wrong. Recall from Genesis 2:8-9; 16-17 that God forbade Adam and Eve to eat of the tree of knowledge of good and evil. They did, and humanity suffered from the Fall until the resurrected Jesus sent as He promised the Holy Spirit to be restored to mankind as an indwelling when in repentance. We have the choice.
