As we deal with the roots of persistent sins, one of the graces of the Sacrament of Reconciliation is the grace of destroying the root of sin. Sometimes we limit the Sacrament to the forgiveness of sins and fail to open ourselves to the additional grace of eradication. Sometimes the root remains because we deal with the symptoms of sin and not the cause or source of sin. To get to this root cause or source I need to ask God to lead me into my past where this particular sin began to take root in me. Who, when , where, how are the questions to ask. Because a particular situation happened in my life either in fact or in perception, which was never fully reconciled through mutual forgiveness, then the root of the past continues to lead me into sin today. We are talking about the grace of healing of memories.  A person may be struggling with anger not as an occasional sin but as a core sin in life. Each time we go to confession we confess the sin of anger. We never ask the question what is the root of my anger? We never ask God to lead us to the root or source. If we do and find that a certain person was the source of anger, then we need to bring this to the Lord.
