I drove by a church I used to go to, and my resentments of how things had all ended in that last year sprang to mind. We went there for ten years, with many positive experiences and wonderful people.
I once preached on what the "forgetting" part of forgive and forget means. Some of you may have been present for that, or some other instance where I spoke about it. I have written a fair bit about forgiveness and the myths about it over the years, but that point doesn't seem to be in the AVI corpus. The summary is this: forgetting a sin against you means two things. First, we officially forget. Even if the action takes up space in our brain, or even consumes us, we resolve not to hold the action against the other person. We do not slyly get back at them with hints to others years later; we do not deny them a tenor solo or a job kind word we would give to others. We may, of course, take all information into consideration when we are making a judgement that affects others. A person who has molested children should not be working with them again - and those who ask to must be among the most suspect. But such a person might yet be trusted as church treasurer, or on the leadership council in charge of properties. That is the first step of "forgetting."
But more important for me today is part two of forgetting: the idea that one does not nurse grievances. Whatever else forgetting might mean, it means at minimum that we do not rehearse the trespasses against us. I recalled incidents and carried on imaginary conversations all day with Christian brothers and sisters who have likely long forgotten the incidents in question. I scored points against them repeatedly in my argument. Not only did I not forget, I went out of my way to remember.
Forgetting the sin does not mean that we flagellate ourselves when we find we that our memories still work. But it does mean that we do not drink the bitter cup to the bottom, slam it down, and ask the universe to fill it that we might drink again.
