I question the validity of taking people on trips down Memory Lane to heal their memories from past hurts. Most such memories are long forgotten from the conscious mind. I know that some can surface and trouble the conscience of those who have been forgiven. But Memory Lane can become Elm Street if we walk people down it too often.
When we are “born again” (“born from above”) our spirit is instantly charged with the life of God. But our mind needs to be “renewed” by the word of God through a process. The Apostle Paul writes about it in Ephesians 4:23, and about the process in the verses that follow.
The last thing that God wants is for us to exhume that foul carcass of the old life so that we can do an autopsy on it. That old life was “buried with Christ in baptism” and the new life that arose from the waters of baptism (symbolically speaking) has nothing in common with the old, buried one. I say again: the spirit is renewed instantly, the moment we are born again; but the mind is renewed through an ongoing process that reprograms it through God’s Word.
The conflict that exists between a believing heart and a haunted mind can result in self-condemnation, lack of prayer and devotion, and a loss of desire to fellowship with other Christians. We need to live the dream, not relive the nightmare. Think of your mind as needing an upgrade and reprogram it through the scriptures as though inserting a new program or app into your computer.
That said, some people need the ghosts of things past removed, and some ministries are very good with a broom! More power to them!
