How do you get them out? Memory is highly efficient in remembering wrong. Although it forgets unpleasant and worthless things (like the last time you tripped or missed what you were aiming for) it NEVER forgets unrighted sin. Much mental illness today can be traced to guilt never wiped from the mind by confession, restitution and forgiveness. Shock, drugs and other medical and psychiatric treatment tries to take such guild memories from the mind, but God's method is the only really effective one -- FACE each wrong with its full load of guilt -- but don't HOLD it! Bring it out into the open before the Lord Jesus, confess it to Him and to those "others" involved -- then receive healing forgiveness.
