When we see a person who has committed vicious sins and crimes escaping with impunity, we react with indignation. We want to see that person called to account and punished, and feel angry that this has not happened. But at such moments we should reflect on our own actions; indeed we should turn that sense of indignation inward against ourselves. Each of us should ask: “How many sins have I committed against others, when I have escaped with impunity?” There are, no doubt, many examples in all our cases. Recognizing this fact will cause our anger against others to melt away. More importantly, it will make us turn to God and ask forgiveness of these sins. Yet there is perhaps a difference between our own sins and the sins which we notice in others. Our own sins are probably quite subtle and inconspicuous, whereas the sins of others are obvious and gross. Should we, therefore, regard our own sins as less important or die? On the contrary, we should realize that subtle sins are frequently the most harmful. Obvious sins, such as robber and violence, are easily recognized, and so can often be guarded against by physical means. The more subtle sins, such as lying and slander and power-mongering are frequently hard to spot, and so difficult to prevent.
