Luke 11:33-36

33“No one after lighting a lamp puts it in a cellar, but on the lampstand so that those who enter may see the light. 34Your eye is the lamp of your body. If your eye is healthy, your whole body is full of light; but if it is not healthy, your body is full of darkness. 35Therefore consider whether the light in you is not darkness. 36If then your whole body is full of light, with no part of it in darkness, it will be as full of light as when a lamp gives you light with its rays.”
