What are Angels? The word "angel" is derived from the greek word "angelos" which means "messenger". They can also be called "son of God". Angels are supernatural beings created by God that protects us: the human race. Angels were created to minister and guard us; they are the heirs of salvation. Angels are among us all the time to help, to guide and to give us inspiration. All of us have a guardian angel watching over us to protect us from negative energies.
