Prayer of St. Anselm

Hope of my heart, strength of my soul, help of my weakness, by your powerful kindness complete what in my powerless weakness I attempt. My life, the end to which I strive, although I have not yet attained to love you as I ought, still let my desire for you be as great as my love ought to be.
