Back in March of this year I read the book, The Way of Serenity: Finding Peace and Happiness in the Serenity Prayer by Father Jonathan Morris. A good friend suggested I read it and, even though I had a lot of issues with the book (fundamentally), this one quote made the whole book worth reading:
I went in to do my confession, and I told the priest what I was going through. The priest was so old that I don’t know if he could even hear what I was saying. He didn’t offer me any spiritual advice about the sins I confessed, but what he did say turned my life upside down. “Young man, keep in mind that the devil wants you to be a good man, and just a good man.” Like a knife to the heart, I knew I was being tempted to mediocrity.
