It is wrong to say that we should just forget the past, for the simple reason that the past will one day be our entire life. Past, present, and future are aspects of our soul that need to be reconciled to God. We must take our living hurts from the past to those who can heal them. We can bring to light patterns we have learned from our parents and other adults, confess those destructive patterns, disagree with them, and repent from them. If we have wronged people, we must confess our sin, apologize to those we have hurt, and make amends. Though none of these processes change the past, they can redeem the past. God is in the process of reconciling everything that has gone wrong, including our personal past. But in order for him to deal with our past, we need to bring all of our broken parts to him.
