About Heavenly Guardian Angels:
Heavenly angels, often referred to as guardian angels, are mentioned numerous times in the Scriptures. Therein we learn that angels are spiritual beings created by God to serve him, and sent by God to watch over the human race, to deliver his message, to guard and protect us from danger, to do battle with other spiritual beings on our behalf.
Since the beginning of time, angels have delivered God's messages to mankind. Sometimes the messages are warnings of impending danger, sometimes instructions as to what to do in a particular situation, sometimes they are simply "there" as protection from enemy forces. Sometimes they bring joyful announcements as in the day they announced the birth of Jesus.
Why do we need angels? In truth, God can deal with us in any way that pleases him to do so. He can speak with us directly, in a burning bush, in dreams, visions and specifically through the Scriptures. Yet, he also employs angels. The Scripture says angels were created for his pleasure. Perhaps it is as simple as that -- it pleases God to send the supernatural heavenly beings we call "angels" to minister to his children.
