In essence, forgiveness is the paramedics coming to patch you up after you've rolled your car and find yourself upside down in a ditch. Rules about sin are guardrails designed to keep you on the road and stop you from rolling your car in the first place.
Folks like that priest don't like it when we're judgmental of each other. They don't like to preach about rules and regulations or seem small minded. However, they also don't like to preach about the sins that led to little Taniqua Wilson being abused by her baby mama's live in boyfriend or the ones that led to Joe Smith's meth addiction. We hear a lot about forgiving Taniqua's mom and Joe, but some of us think it might be better to be asked to forgive just a little less often.
