What I mean is that there is nothing fresh or creative or new or positive or profound about sin. Evil is always derivative. The devil cannot create anything. All he can do is destroy or distort what is good.
And that’s why evil is evil–because it is the destruction or the distortion of something good.
A lie is the distortion of the truth. Lust is the distortion of love. Stealing is the destruction of proper ownership. So you may go on and never once find a sin that is original.
The negativity of sin, therefore, is a lost opportunity. It is a chance of goodness that was lost, a chance for holiness that was thrown away, a chance for light that was darkened, a chance for love that was wasted.
