“Their sins and lawless acts I will remember no more.”
(Hebrews 10:17 NIV)
God says He’ll remember our sins “no more,” which means that God will never use the past against us (Psalm 103:12), not that He’ll forget our sins because God doesn’t forget. Similarly, we can’t forget the wrong that was done to us, even after we choose to forgive the person who hurt us. Only with time do we truly learn to “forget” and experience healing. However, the forgiveness is there even if we don’t feel it right away. So while forgiving may be a onetime decision, forgetting may take a lifetime.
It doesn’t take much to forgive, but it takes much more to forget.
