Nathan,
I don't know your age but asking Reba to forget that is akin to asking me to, and expecting me to forget find my best friend after a Mortar hit him in the chest or forgetting the night the Gooks overran us. I tried to forget for better than thirty years and the nightmares got worse every week.
Some things should impact a person so that only the Glorified Body will erase them.
I think my thoughts are not being taken the right way. I am not saying someone can forget, as in wipe away memories.
Forgetting is a choice. You cannot choose the memories you retain.
You can choose to not bring them to mind, then dwell in them. I think people don't understand that forgiveness follows repentance.
I really think we view forgiveness as God does 'overlooking'.
Acts 17:30 (ESV)
The times of ignorance God overlooked, but now he commands all people everywhere to repent
God overlooks sins of all people. He has too otherwise we would all be destroyed. However, He forgives those who are repentant. The same is true with us. We overlook those sins, and forgive the ones which are repentant.
Difference is? Overlooking just looks past the sin as done and an event that cannot be changed. It does not nessitate the same actions as forgiveness. Only the restraint of retaliation. I think most people think this is forgiveness.
