The Westminster Shorter Catechism answers the fourteenth question, “What is sin?” by the response, “Sin is any want of conformity to, or transgression of, the law of God.” Here we see sin described both in terms of passive and active disobedience. We speak of sins of commission and sins of omission. When we fail to do what God requires, we see this lack of conformity to His will. But not only are we guilty of failing to do what God requires, we also actively do what God prohibits. Thus, sin is a transgression against the law of God.

“The sinfulness of sin” sounds like a vacuous redundancy that adds no information to the subject under discussion. However, the necessity of speaking of the sinfulness of sin has been thrust upon us by a culture and even a church that has diminished the significance of sin itself. Sin is communicated in our day in terms of making mistakes or of making poor choices. When I take an examination or a spelling test,if I make a mistake, I miss a particular word. It is one thing to make a mistake. It is another to look at my neighbor’s paper and copy his answers in order to make a good grade. In this case, my mistake has risen to the level of a moral transgression. Though sin may be involved in making mistakes as a result of slothfulness in preparation, nevertheless, the act of cheating takes the exercise to a more serious level. Calling sin “making poor choices” is true, but it is also a euphemism that can discount the severity of the action. The decision to sin is indeed a poor one, but once again, it is more than a mistake. It is an act of moral transgression.

In my book The Truth of the Cross I spend an entire chapter discussing this notion of the sinfulness of sin. I begin that chapter by using the anecdote of my utter incredulity when I received a recent edition of Bartlett’s Familiar Quotations. Though I was happy to receive this free issue, I was puzzled as to why anyone would send it to me.
