Luke 11:34-36

New Revised Standard Version, Anglicised

³⁴ Your 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. ³⁵ Therefore consider whether the light in you is not darkness. ³⁶ If 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.’
