I have a feeling most people have an "angel" story to tell if they think about it...the kind where they absolutely know they would have died or been seriously injured, yet miraculously lived and were kept safe, and give credit to an angel for their safety. I can think of multiple times in my life of having this experience, though I have not actually seen an angel with my physical eyes that I know of.
You are so very right. However, when we do that we are giving credit to an angel instead of the Holy Spirit, the Comforter who Jesus said whould do exactly those things for us.
