DEAR BILLY GRAHAM: I know the angels were very much a part of Jesus’ birth (for example, in making the announcements to Mary and the shepherds), but do they still do anything? Or are angels no longer active? — J.M.

DEAR J.M.: The Bible makes it clear that God’s angels are still very much at work, although their ministry is largely unseen by us. Even when they take human form (as they can do on occasion), they may not be recognized as angels.

What do the angels do? Occasionally, God may entrust them with special messages, just as he did when the angel Gabriel told Mary she would become the mother of the son of God, Jesus Christ (see Luke 1:26-38).

But for the most part the angels have been given the unseen task of watching over God’s people and guarding them from spiritual and physical harm. Only in heaven will we realize just how much they did for us. We should thank God for sending them to watch over us.
