God created angels for His own use; they belong to Him. Angels worship God, and they are spiritual beings. They are in human form with wings; they are the messengers of the Living God; they take message from God to people, and they also help people God sends them to help.
They do what God tells them to do and go wherever God sends them. They are obedient to God. They protect the people of God and they fight on their behalf. I call them the spiritual bodyguards on earth because they protect the people of God from their enemies. They are like presidential bodyguards here on earth.
