We live in an age when the idea of sin is dismissed as a relic of an outmoded religious system designed to suppress one’s desires for happiness. As we’ve seen so abundantly recently, in our entertainment media and all the way to the Supreme Court, equality has now been applied to same-sex relationships. Anyone who disagrees with this new enlightenment is archaic. Our society needs the message that is at the very ground level of Christian understanding: all men are sinners, and we cannot cover up those sins by calling them something else. In The Problem of Pain, C. S. Lewis instructs us,
A recovery of the old sense of sin is essential to Christianity. Christ takes it for granted that men are bad. Until we really feel this assumption of His to be true, though we are part of the world He came to save, we are not part of the audience to whom His words are addressed.
In other words, the salvation message cannot come across to us until we are willing to recognize our sins. Lewis also describes how sin distorts every good thing God provides. In Letters to Malcolm: Chiefly on Prayer, he writes,
The only way in which I can make real to myself what theology teaches about the heinousness of sin is to remember that every sin is the distortion of an energy breathed into us—an energy which, if not thus distorted, would have blossomed into one of those holy acts whereof “God did it” and “I did it” are both true descriptions. We poison the wine as He decants it into us; murder a melody He would play with us as the instrument. We caricature the self-portrait He would paint. Hence all sin, whatever else it is, is sacrilege.
This sense of sin must return to our society. If it does not, we are lost.
