One I must preface: I'm not religious and with the Church I have nothing the hat - apart from the church tax. The Bible, I know mainly from hotel rooms. Religious instruction is decades ago, but I still remember that I always found the coolest of all the angels Bible heroes ... even cooler as Moses or Jesus.
Why? - Angels are helpful and strong. They are the people in times of special need for, and guards with the flaming sword at the entrance to Paradise. As eternal beings, they are more beautiful than anything we can imagine. Of course, they are far superior to the people and not tied to the limitations and conditions of human physical world. And when the final battle between good and evil has come, the angels will fight at the front line.
When I got older, my image of angels was human. Should it really be angels, it would also them in their job sometimes listless or tired. I imagine that m a guardian angel in a Bar drinks, while I risking the bungee-jumping my life. Probably he also sleeps better in while I was struggling through the early morning traffic jam. My angel is playing electric guitar instead of harp. He does not fly through the air alone, but always with a dashing blond angel by his side.
lot has changed since I was thirteen, but I still find cool angel.
