Sin means I did it on purpose. Sin means it was willful. You know, I planned this and I did this. Sin means I knew it was wrong when I did it, and that doesn’t make me feel very good about myself. In fact, if I have sins, then after a while I think I’m kind of a bad person. So, we don’t use that word. We like this word: "I didn’t sin. I just made a mistake. I made a mistake."
