A PRAYER FOR PROTECTION

O My God, I adore Thee and I love Thee with all my heart. I thank Thee for having created me, for having made me a Catholic and for having watched over me this day. Pardon me for the evil I have done this day; and if I have done any good, deign to accept it. Watch over me while I take my rest and deliver me from danger. May Thy grace be always with me.  Amen
