to atone...

I believe that atonement for past sins is possible. I think that a simple apology can go a long way. Addressing a past wrongdoing or sin is a noble deed and is much more beneficial than doing nothing and hoping that the action gets forgotten by itself. In my younger years, I had an acquaintance that my friends and I used to pick on. Even at the time, I realized that what I was doing was wrong but I never did anything about it or addressed it. Several years later, I went and apologized for my past actions. Peace was made between us, and we both felt better afterwards.
