Healing Prayer for my Mother

Hi everyone, I would greatly appreciate your prayers- about 1 week ago my mother fell and broke her wrist and is now in a cast and sling, just yesterday they had to do surgery and installed screws and a metal plate to get it to heal, I was just visiting my mother this morning and she was in severe pain despite powerful pain medication. Both of my parents are elderly and are not saved and their hearts are not open to the gospel, there have been many times when I asked if I could pray for them and they said no. They are involved in a unitarian church, they believe all religions are equally valid, it is a demonic thing. Please pray for my mother's healing and for the pain to go and also for both of my parent's salvation and that their hearts would be open to the gospel! My parent's names are Denny and Lila. Thank you!
