O Thou holy and unspeakable, Thou wonderful and mighty God, whose power and wisdom hath no end, before whom all powers tremble, at whose glance the heavens and the earth flee away, Thou art Love, Thou art my Father, and I will love and worship Thee for ever and ever! Thou hast deigned to show pity on me, and a ray from Thy light hath shone upon mine inward eye. Guide me on into the perfect light, that it may illumine me wholly, and that all darkness may flee away. Let the holy flame of Thy love so burn in my heart that it be made pure, and I may see Thee, O God; for it is the pure in heart who see Thee. Thou hast set me free; Thou hast drawn me to Thee; therefore forsake me not, but keep me always in Thy grace. Guide me, and rule me, and perfect me for Thy kingdom—Amen.

St. Augustine (354–430).
