Luke 11:33-36

33“1No one lights a lamp and puts it away in a cellar nor under a basket, but on the lampstand, so that those who enter may see the light. 342Your eye is the lamp of your body; when your eye is 3clear, your whole body also is full of light; but when it is 4bad, your body also is full of darkness. 35So watch out that the light in you is not darkness. 36Therefore if your whole body is full of light, without any dark part, it will be wholly illuminated, as when the lamp illuminates you with its light.”
