Mathew West has a song, 'Forgiveness', that talks about how important it is. It's something that is sorely needed in the world today. Forgiveness does more for the person forgiving than the person being forgiven.
I don't understand people who think they are higher than others and their sins aren't as bad. In order to have those thoughts you have to be judging.why waste time judging people, that is God's job. Our job is to love and help one another.
