Luke 11:33-36 - Light And Darkness
33 But no man lighting a lamp putteth it in a concealed place, or under a bushel, but on a stand, that they who are coming in, may see the light. 34 The lamp of the body is the eye: when therefore thine eye is clear, thy whole body will be luminous, but if it be vitiated, thy whole body will be darkened. 35 Let it be thy aim then, that the light which is in thee do not become darkness. 36 If then thy whole body be illuminated, not having any dark part, it will be wholly luminous, as a lamp by its brightness diffuseth light.
