I once spoke to a woman who was struggling to show true empathy for her mother, who was an alcoholic and had given this woman many terrible childhood memories.  She felt that there was no way she could care for her now very sick mother - and she wished God could send an angel to come from Heaven and care for her mother for her.  We look at angels in the Bible, in particular, in the Book of Daniel.  We see God send these heavenly beings to rescue people.  We also consider how this woman with the sick mother solved her dilemma of trying to show genuine love for someone she couldn't help but resent.
