557 O Christ, who art the Light and day,

1 O Christ, who art the Light and day, Thy beams chase night's dark shades away; The very Light of light Thou art, Who dost that blessed light impart. 2 All-holy Lord, to Thee we bend, Thy servants through this night defend, And grant us calm repose in Thee, A quiet night from perils free. 3 Let not dull sleep the soul oppress, Nor secret foe the heart possess, Nor Satan's wiles the flesh allure, And make us in Thy sight impure. 4 Light slumbers let our eyelids take, The heart to Thee be still awake; And Thy right hand protection be To those who love and trust in Thee. 5 O Lord, our strong defense, be nigh; Bid all the powers of darkness fly; Preserve and watch o'er us for good, Whom Thou hast purchased with Thy blood. 6 Remember us, dear Lord, we pray, Whilst burdened in the flesh we stay; Thou only canst the soul defend, Be with us, Savior, to the end.
