Eternal Light, before Whom all darkness is light, and, in comparison with whom, every other light is but darkness! May it please Thee to send forth Thy light and Thy truth, that they may lead us. Purify, we pray Thee, our souls from all impure imaginations, that Thy most beautiful and holy image may be again renewed within us, and, by contemplating Thy glorious perfections, we may feel daily improved within us that Divine similitude, the perfection whereof we hope will at last make us forever happy in that full and beatific vision we aspire after. Till this most blessed day break, and the shadows fly away, let Thy Spirit be continually with us, and may we feel the powerful effects of Thy Divine grace constantly directing and supporting our steps; that all our endeavors, throughout the whole remaining part of our lives, may serve to promote the honor of Thy blessed Name, through Jesus Christ our Lord—Amen.

Robert Leighton (1611–1684).
