Idea of having a guardian angel
Man has always been facinated with the idea of having a guardian angel. The idea that God has thousands of supernatural assistants ready, willing and able to assist us mortals in our hour of need appeals to us and gives the idea of a devine being and Heaven a little more credence.
To believe in the existence of Guardian Angels is the ultimate step of trust in one’s faith, for it means taking control out of human hands and giving it to something that may or may not exist. For those who believe, it is a self-fulfilling choice, for if God’s power derives from belief in him, then his angels also benefit in the same way and are thus able to help those who call on them consciously or not.
