Here are a couple of remarkable examples of angels saving people’s lives by warning them about the imminent danger of fire.
When my sister and I were young and lived in South Africa we shared a room. One extremely cold winter night we had put a heater between our beds. Early the next morning something woke me and I saw a figure in a white robe with long golden hair next to my bed. I noticed that my eiderdown had fallen on the floor against the heater and had started burning. I got out of bed and moved it away. At the time I had no idea that I had seen an angel.
Years later I related the story to my sister. I thought she had been asleep at the time, but she had also seen the angel. Had it not woken me, both our beds would have caught alight! We were saved by that angel.
