Herald Angels

This is a little tongue in cheek but when we sing ‘Hark the Herald Angels sing,’ I wonder if these angels have other roles or whether heralding is their main job. What about the angels who are at the bedside of sick children and the dying? Who are the angels who keep us ‘lest we dash our foot against a stone’? Are there angels who take on human form and guide the lost traveller in the form of another traveller, or a person who arrives at just the right time?

I obviously don’t know much about the role of angels but I do thank God He sends them to work on this earth.
