Funny, but forgiveness is the sermon topic for a few weeks...
I was talking with someone about forgiveness and forgetting and they led me to an interesting revelation. You can forgive and "forget" a past hurt, but not one that keeps happening. And the "forget" part is not completely forgetting, but, like a scar, you learn from it so you don't fall into that same hurt again. But... you don't focus on the scar and relive what caused it day after day.
I know that with God, I can be forgiven and He'll forget my past sins. I want the slate wiped clean. But I know that being a broken human, I can't do that completely.
