Some memories are unwelcome, dark shadows that creep in without invitation. They make reliving the pain torturous.
If you are a victim of painful memories, there is hope. It is not a pat answer or a quick fix by any means. But you must know that God, the Creator of mankind, provides comfort and peace. The memory will not have access whenever it pleases when you learn that God will help you through your pain.
Ask Him. He hears every prayer. I promise.
