By Peter Giersch, Catholic Exchange - C. S. Lewis points out that the reason the saints know more about sin than the sinners do is that you don’t really understand rules until you obey them. How many times have you said, under your breath, after a moral struggle, in a flash of understanding, “Oh that’s why…” Understanding is possible. Understanding may come, but obedience comes first... Now of course all of this can be applied to daily temptations. Why can’t I get angry in traffic? Why can’t I watch this video? Why shouldn’t I join in this conversation? Because it’s not allowed. Just obey.
