Angels figure prominently in the NT. People don’t really know this, or they overlook angels in the created order. At the other end of the scale, some are so preoccupied with angels they nearly fall into angel worship.

With Christmas coming up, we will be singing about angels. “Angels We Have Heard on High,” and “Hark the Herald Angels Sing,” and “It Came Upon A Midnight Clear” come to mind.

Once you start studying angels, you realize how frequently they are mentioned in the New Testament. And as for the nativity story, they figure prominently, making many appearances!
