Many people today say 'that they believe in angels.' And many do claim that angels visit them on at their moments of need. Back in the 1980's for a time there were a plethora of stories and claims made by people that they picked up angels in their cars, who then disappeared. 

The Bible has much to say to us about Angels.

Angels food. Eaten by humans...

From heaven he sent grain that they called manna. He gave them more than enough, and each one of them ate this special food. Psalm 78:24-25.

Ministry of angels towards believers. Guide...

The Lord God of heaven, who took me from my fathers house and from the land of my birth, and made an oath to me, saying, To your seed I will give this land: he will send his angel before you and give you a wife for my son in that land. Genesis 24:7.

Ministry towards unbelievers. A destruction.

And at nightfall the two angels came to Sodom; and Lot was seated at the way into the town: and when he saw them he got up and came before them, falling down face to the earth. Genesis 19:1,

Not to be worshiped.

Let no man take your reward from you by consciously making little of himself and giving worship to angels; having his thoughts fixed on the things which he has seen, being foolishly lifted up in his natural mind. Colossians 2:18.
