Yes, they do. God’s creation for sure is not restricted to this visible and empirical world (as the man in his pride thinks). We do not control God’s creation. God’s world is much more abundant, colorful, exquisite, and amazing than we with our sciences can observe.

The angels are not, however, the focus in Christianity, even though sometimes we live through some kind of an angel boom. When you read the Gospels, you notice that the angels are connected to the most important turning points in the life of Jesus. They are also called as serving spirits. They then fulfill the mission God has given to them here on earth. Above all, they serve the goal of saving souls.

Are they not all ministering spirits sent out to serve for the sake of those who are to inherit salvation?
(Hebrews 1:14, ESV)
