How do angels minister to us? Again, we are not sure and it probably varies on a case by case basis. We have instances in the Bible of angels appearing in human form to warn people of concerns (see Abraham). We even have a special promise in the Bible that those who serve the unfortunate. It states that as we give to people in need we have at times “served angels without knowing it”. Still, for the most part the Bible is pretty quiet about how these angels serve us. It just promises they do.
So what do we do with this vague verse? Well, first let’s take it in context. The entire book of Hebrews is written to stop bad “theology.” People were worshiping angels and elevating them to great status. Essentially, by pointing out angels are sent to minister to mankind the author instantly places angels in a slightly different role—certainly not one of deity. We don’t know a great deal about angels. We know they do exist to worship and serve God and we do know many have been assigned to minister to us. This implies that as Christians we have beings serving us that we don’t even know about. Do they keep us physically safe? Probably at times. Do they laugh and cry with us when good and bad things happen? Probably. Perhaps their greatest service is they know about spiritual battles going on around us that we are unaware of and fight for us.
