O Lord Jesus Christ, the True Light that enlighteneth every man that comes into the world: Do Thou pour out Thy blessing upon these candles, and sanctify them with the light of Thy grace. And be pleased, O Merciful One, that as these lights, kindled with visible fire, drive away the darkness of night, so may our hearts, kindled with invisible fire, and illumined with the brightness of the Holy Spirit, banish the blindness of every sin, that, by the cleansing of our spiritual eyes, we may be able to see that which is well-pleasing unto Thee and necessary for our salvation; and that having triumphed over the dark forces of this world, we may be counted worthy to attain to the everlasting Light. For Thou art our Savior, and unto Thee do we send up glory, together with Thy Father Who is without beginning, and Thy Most-holy, Good, and Lifegiving Spirit, now and ever, and unto the ages of ages. Amen.
