And the light shines in darkness; and the darkness comprehended it not.
If persons who can see are shut up together with others who are blind, in a perfectly dark room, the seeing and the blind are in the same situation; no object is perceived by any, no colours discerned; but if light is introduced into the room, there is then a wonderful difference. To those who are endowed with sight, every object appears in its true form and just colouring; but to the blind all things remain as they were; they are in darkness still; and this because the darkness is in themselves. So it is with the outward revelation of Divine truth: while it is withheld, all are in darkness, but it may shine not only on those who live, and are awake, and can see, but also on the dead, and on the sleeping, and on the blind.
(J. Fawcett, M. A.)
