There are scores of passages in both the Old and New Testaments that describe the roles that angels fulfill in God's plans for mankind. Below is a representative sample.

 

With the coming of dawn, the angels urged Lot, saying, "Hurry! Take your wife and your two daughters who are here, or you will be swept away when the city is punished." When he hesitated, the men grasped his hand and the hands of his wife and of his two daughters and led them safely out of the city, for the LORD was merciful to them. As soon as they had brought them out, one of them said, "Flee for your lives! Don't look back, and don't stop anywhere in the plain! Flee to the mountains or you will be swept away!" (Gen 19:15-17)

 

 

See, I am sending an angel ahead of you [the Israelites who have been delivered from bondage in Egypt] to guard you along the way and to bring you to the place I have prepared. Pay attention to him and listen to what he says. Do not rebel against him; he will not forgive your rebellion, since my Name is in him. If you listen carefully to what he says and do all that I say, I will be an enemy to your enemies and will oppose those who oppose you. My angel will go ahead of you and bring you into the land of the Amorites, Hittites, Perizzites, Canaanites, Hivites and Jebusites, and I will wipe them out.  (Exo 23:20-23)

 

 

Elijah was afraid and ran for his life. When he came to Beersheba in Judah, he left his servant there, while he himself went a day's journey into the desert. He came to a broom tree, sat down under it and prayed that he might die. "I have had enough, LORD," he said. "Take my life; I am no better than my ancestors." Then he lay down under the tree and fell asleep. All at once an angel touched him and said, "Get up and eat." He looked around, and there by his head was a cake of bread baked over hot coals, and a jar of water. He ate and drank and then lay down again. The angel of the LORD came back a second time and touched him and said, "Get up and eat, for the journey is too much for you." So he got up and ate and drank. Strengthened by that food, he traveled forty days and forty nights until he reached Horeb, the mountain of God. (I Kin 19:3-8)

 

 

The angel of the LORD encamps around those who fear him,
       and he delivers them. (Psa 34:7)

 

 

If you make the Most High your dwelling—
       even the LORD, who is my refuge—

then no harm will befall you,
       no disaster will come near your tent.

For he will command his angels concerning you
       to guard you in all your ways;

they will lift you up in their hands,
       so that you will not strike your foot against a stone. (Psa 91:9-12)

 

 

This is how the birth of Jesus Christ came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be with child through the Holy Spirit. Because Joseph her husband was a righteous man and did not want to expose her to public disgrace, he had in mind to divorce her quietly.

 

But after he had considered this, an angel of the Lord appeared to him in a dream and said, "Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins." (Mat 1:18-21)

 

 

After the Sabbath, at dawn on the first day of the week, Mary Magdalene and the other Mary went to look at the tomb. There was a violent earthquake, for an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it. His appearance was like lightning, and his clothes were white as snow. 4The guards were so afraid of him that they shook and became like dead men. The angel said to the women, "Do not be afraid, for I know that you are looking for Jesus, who was crucified. He is not here; he has risen, just as he said. Come and see the place where he lay. Then go quickly and tell his disciples: 'He has risen from the dead and is going ahead of you into Galilee. There you will see him.' Now I have told you." (Mat 28:1-7)

 

 

So Peter was kept in prison, but the church was earnestly praying to God for him. The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance. Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. "Quick, get up!" he said, and the chains fell off Peter's wrists. Then the angel said to him, "Put on your clothes and sandals." And Peter did so. "Wrap your cloak around you and follow me," the angel told him. Peter followed him out of the prison, but he had no idea that what the angel was doing was really happening; he thought he was seeing a vision. They passed the first and second guards and came to the iron gate leading to the city. It opened for them by itself, and they went through it. When they had walked the length of one street, suddenly the angel left him. Then Peter came to himself and said, "Now I know without a doubt that the Lord sent his angel and rescued me from Herod's clutches and from everything the Jewish people were anticipating." (Act 12:5-11)
