One of the major roles of angels is to serve mankind, and within this role, they often serve guardians, as well as God’s messengers, furthering the Lord’s divine purposes of human salvation.

Simply put, one of the primary roles of angels is to do God’s will.

Bless the LORD, all His angels mighty in strength, who do His word, who hearken to the voice of his command.

– Psalm 103:20

To serve mankind

“Are they not all ministering spirits sent out to serve for the sake of those who are to inherit salvation?”

– Hebrews 1:14

This verse clarifies one of the roles of angels, which is to help steer mankind away from sin and toward salvation.

Pastor John MacArthur writes: “The angels’ destiny is to serve forever those who are heirs of salvation. What a wonderful, awesome prospect for Christians! In addition to being forever in God’s presence, our destiny is to be served by angels forever.”

The difference between angels and demons

Conversely, we know that fallen angels, also known as demons, are in rebellion against God. These angels said they will not serve mankind. They feel that they are more intelligent and superior and should not have to serve inferior mankind.

Satan or Lucifer, who is an angel himself, and the rebellious angels, refused to serve mankind and were cast out of heaven. (2 Peter 2:4, Jude 1:6, Revelation 12:9)

Now, these angels do the opposite of God’s will. Rather than helping to steer mankind away from sin and toward rebellion, they work to tempt mankind into sin and away from salvation.

Guardians for mankind

For He will command His angels concerning you to guard you in all your ways.

– Psalm 91:11

Satan, being an angel himself, knows the role of angels as guardians. Satan quoted the above verse to Jesus during his temptation of forty days in the wilderness.

“Then the devil took him to the holy city and set him on the pinnacle of the temple and said to him, “If you are the Son of God, throw yourself down, for it is written, “‘He will command his angels concerning you,’ and “‘On their hands they will bear you up, lest you strike your foot against a stone.’” Jesus said to him, “Again it is written, ‘You shall not put the Lord your God to the test.’””

– Matthew 4:5-7

After Jesus temptation had finished, the Bible tells us:

“Then the devil left him, and behold, angels came and were ministering to him.”

– Matthew 4:11

One of the most well-known stories in the Bible that is an example of Guardian Angels is a story of Daniel in the lion’s den. In the Bible, the prophet Daniel was prohibited by the command of the King against praying to his (Daniel’s) God.

But Daniel continued to pray. The king had Daniel thrown into a lion’s den to be devoured. But through Daniel’s faith, trust, and submission to God’s will – God sent his angels to protect Daniel from the lions.

My God sent His angel and shut the mouths of the lions. They have not hurt me, for I was found innocent in His sight, and I have done no wrong against you, O king.”

– Daniel 6:22
