How often to we think of or even realize that God has given each one of us and Angel. In Matthew 18:4 He reminds us "Whoever humbles himself like this child, he is the greatest in the kingdom of heaven... (10) for I tell you that in heaven their angels always behold the face of my Father who is in heaven.
In Psams 91:11 "For he will give his angels charge of you to guard you in all your ways" and the angels are his "ministering spirits sent forth to serve, for the sake of those who are to obtain salvation" (Hebrews 1:14)
"From infancy to death human life is surrounded by their (the angels) watchful care and intercession. Beside each believer stands an angel as protector and shepherd leading him to life. Already here on earth the Christian life shares by faith in the blessed company of angels and men united to God." - from the Catechism of the Catholic Church; 336.
My mother taught me this prayer. Remember this:
Angel of God, my Guardian dear, to whom His love commits me here, ever this day (or night) be at my side, to light and guard, to rule and guide. Amen.
Prayer - Lord give me strength of will and courage to refuse what is evil and to choose what is good. Amen
