I hear a lot about forgiveness. As a Christian, it's a pretty big deal. In fact, it's such a big deal that it's commanded. If you don't forgive others, you will not be forgiven. The Lord's Prayer says "Forgive us our debts, AS WE FORGIVE our debtors." Apparently, there's no way around it.
Even so, I think that it's not necessarily understood in the same way that other commands are understood. I know how to not murder people, or so I think. Then, I remember that Jesus ups the stakes and says that hatred is murder. So, really, I don't actually know much about what to do. However, I do know a little bit about what forgiveness isn't. I say a little bit, because I am coming to understand this daily, and much more deeply. It's still a raw and fresh place in me; be gentle with the things I have gotten wrong or phrased incorrectly.
