If we keep reliving the unhappy moment and devote endless hours to appealing the verdict of a wrongdoing in our minds, we will be left spent and miserable. Though it is sometimes hard to see, time passed in the courtroom of our mind trying the case over and over is really time wasted. Even though we're sure the verdict is guilty, there is usually no way to bring about justice in this life without becoming guilty ourselves. Our best (and sometimes only) recourse is to ask the Lord to change our inner life - to use this evil to bring about good in us.
