Of course angels are not deceased people. I remind people of this fairly often.
My aunt died four years ago. About six months after she died, an old boyfriend of hers, who was 92, fell on the ice outside his house, and was unable to get up. He said aloud, “Who is going to help me now?”
At that moment, he saw my aunt. She said, “I’ll get help for you.”
His wife, who had Alzheimer’s so bad she no longer recognized him, saw him from the back door, went to the phone, dialed 911, and summoned help.
Amazing story.
