Luke 11:34-36

Moffatt(i) 34 Your eye is the lamp of the body: when your eye is sound, then the whole of your body has light, but if your eye is diseased, then your body is darkened. 35 (Look! perhaps your very light is dark.) 36 So if your whole body has light, without any corner of it in darkness, it will be lit up entirely, as when a lamp lights you with its rays."
