Healing of Memories
The past needs to be healed as well as the present!
a) Conscious (what I am aware of now), Sub-Conscious (what I am not aware of now, but I have access to it if I seek it), Unconscious (the things which are never available to me, but which continue to impact my life without me being able to remember or bring to my thinking awareness).
*for example. Some people say, "I believe in God's forgiveness, I just don't feel it, I just feel so much guilt." (This means that there is some unconscious healing that needs to take place. Perhaps childhood trauma, perhaps a twisted thought process too deep for awareness, there are any number of sources...) So the response to this experience is to pray in faith, "Father you have promised that if someone is sorry and confesses their sin to you and repents, and asks to be forgiven; You forgive them! I embrace this in faith!
Emotional trauma has a high correlation to physical maladies. (there is a huge number of physical maladies --some say 60% or more--which have brought people to a doctor with no physical cure. Emotions can cripple bodies. Among other things are disorders of digestion, heart issues, cancer, fibromyalgia, arthritis, and headaches. So emotional trauma and problems can produce physical symptoms or generate physical disease.) The psalmist commends us to "cast our burden upon the Lord." Glennon sees value in combining counseling with prayer. (this is not universal. some actually say it is not a good idea, that Jesus never did it. Personally, I have seen healing through counseling, I think it is a healthy input in a different realm. It supplements the prayer and is a means through which the Holy Spirit can be at work.)
b) Root of Bitterness. Resentment may be justified but it still damages the resentful person. Healing relationships, includes apologies and repentance for what we have done wrong. (Hebrews 12:15 "See to it that no one fails to obtain the grace of God; that no root of bitterness springs up and causes trouble, and through it many become defiled.") Glennon thinks that if most physical illness has a connection to emotional problems then healing these needs to take into account the emotional issues--counseling and prayer seek to uncovering the connection. If we are a new creation in Christ, then we have to heal the "old Adam/Eve" (mind, body, spirit). Facing our past and our memories (guilt or wounds) is part of becoming whole.
this is my input. Practically how does one do this? An exercise by yourself is to simply revisit the 'event' and sort of let it run like a movie in your head, or mentally reflect on it as a written story--different people do it different ways. As you do this take note of your thoughts and feelings. The healing of memories can be as simple as asking Jesus to minister to those thoughts and feelings. Perhaps looking to the Crucified as He says, "Father forgive them they know not what they do" will empower you to forgive someone else or receive forgiveness. Perhaps imagining Jesus present with you in the moment and asking His hand of comfort and healing there and then. (you were not alone) Doing this work with another, or a team, is probably better. As you verbalize the event the act of speaking has a deeper impact on your soul. Hearing another speak words or pray prayers over you can also be more powerful.The Holy Spirit can work through others to tell you what you need.
