We can change history.
My daily prayer time begins with prayer for various chronic health conditions. The last one on the list is my right ear: for years, I’ve had significant hearing loss in that ear resulting from a patulous eustachian tube. I believe my youngest brother, my mother, and her mother all have or had the same thing in the same ear also.
One morning, I came to that point in my prayers, and stopped. I noted that I have prayed for that condition every day for many years, and there has never been any change. I said, maybe this is no more likely to be healed in this life, than Verna Moeller’s disfigurement was likely to be healed in this life. She is beyond the veil, now, but at that moment I devoted significant time and energy to her healing.
