The examination of conscience has so often caused me to rethink my own approach to the daily issues of life that I cannot imagine really NOT knowing that Confession was available and efficacious.
Yes. Some bad habits that I had acquired over the past um, 43 years were especially hard for me to deal with. One of the big ones was my salty language. I kept confessing it over and over again, but since I had been attending confession, I also had been receiving Communion - within 5 or 6 months, a habit of probably 25 years or so was completely broken, and it seems to me, with little to no effort on my part, it was/is God's Grace at work.
The other thing I notice is that off-color jokes and stories which I used to find particularly compelling (I work nights with mostly men, so I hear this stuff all the time) has become something which I avoid and find offensive to God. I just smile and walk away or get busy in my cubicle.
I don't miss this stuff at all, and I am so grateful that I avoid the sin and do not contribute to the "occasion of sin" of others.
