Today is the feast of St. Augustine, Doctor of the Church. From the Confessions, Book XIII:
I call upon Thee, O my God, my mercy, Who createdst me, and forgottest not me, forgetting Thee. I call Thee into my soul which, by the longing Thyself inspirest into her, Thou preparest for Thee. Forsake me not now calling upon Thee, whom Thou preventedst before I called, and urgedst me with much variety of repeated calls, that I would hear Thee from afar, and be converted, and call upon Thee, that calledst after me; for Thou, Lord, blottedst out all my evil deservings, so as not to repay into my hands, wherewith I fell from Thee; and Thou hast prevented all my well deservings, so as to repay the work of Thy hands wherewith Thou madest me; because before I was, Thou wert; nor was I any thing, to which Thou mightest grant to be; and yet behold, I am, out of Thy goodness, preventing all this which Thou hast made me, and whereof Thou hast made me. For neither hadst Thou need of me, nor am I any such good, as to be helpful unto Thee, my Lord and God; not in serving Thee, as though Thou wouldest tire in working; or lest Thy power might be less, if lacking my service: nor cultivating Thy service, as a land, that must remain uncultivated, unless I cultivated Thee: but serving and worshipping Thee, that I might receive a well-being from Thee, from whom it comes, that I have a being capable of well-being.
