O Lord Jesus Christ, you are the bright sun of the world—ever rising, never setting—who with one look gives life: preserving, nourishing, and making joyful all things that are in heaven and on earth. Shine brightly, I pray, upon my heart, that the darkness of sin may be driven away by your inward light, and that I, without stumbling or offending you in any way, may walk in the pure light of day all my life. Grant this, O Lord, for with the Father and the Holy Spirit you live and reign for evermore. Amen

-Thomas Cranmer (68, For the Light of Christ)
