Until I prepared for this, I didn't think about examining one's conscience. It's recommended, it's important. It's vital before one confesses. Then confession, then absolution, then penance, or making amends. Amendment of life.
Repentance involves change.
I don't know that I fully experienced that response to confession as a child with parents and teachers. I like that. That speaks to me. It is an understanding of action. Confession and repentance lead to a change in one's life.
