Luke 11:34-36

11:34 Your eye is the lamp of your body. When your eye is healthy, your whole body is full of light, but when it is diseased, your body is full of darkness. 11:35 Therefore see to it that the light in you is not darkness. 11:36 If then your whole body is full of light, with no part in the dark, it will be as full of light as when the light of a lamp shines on you.”
