The Bible doesn’t tell us exactly what angels look like; in fact, they often are invisible to us, because they are spiritual beings who seldom take on any physical appearance.
At times, however, they do become visible. When the prophet Isaiah was given a vision of God’s majesty and glory, His throne was surrounded by angels. They were similar in appearance to humans, with faces and feet, but they also had wings and could fly (see Isaiah 6:1-3). When the angel announced Jesus’ birth to the shepherds outside Bethlehem, the Bible says that “the glory of the Lord shone around them” (Luke 2:9). On the other hand, angels sometimes took the appearance of ordinary men, and were only recognized as angels later (see, for example, Genesis 19).
God created the angels before the beginning of time, and they had one purpose: to be God’s servants. Today, angels watch continually over God’s people, to deliver them from evil and safeguard their entrance into heaven. We may not even think about them very much or realize their importance, but they still watch over us — and we should thank God for them. The Bible says, “Are not all angels ministering spirits sent to serve those who will inherit salvation?” (Hebrews 1:14).
The angels’ work on our behalf should remind us of God’s love for us. At the same time, we are not to worship the angels or give undue attention to them. Christ alone is our Savior, and He alone is the One to whom we should look for our salvation. Have you put your faith and trust in Him?
