Luke 11:34-36

MLV(i) 34 The lamp of the body is the eye; therefore, whenever your eye is clear, your whole body is also radiant, but whenever it is evil, your body is also dark. 35 Therefore, note that the light which is in you is not darkness. 36 Therefore, if your whole body is radiant, not having any part dark, it will be entirely radiant, as whenever the lamp illuminates you with its rays.
