Luke 11:34-36

Revised Standard Version

³⁴ Your eye is the lamp of your body; when your eye is sound, your whole body is full of light; but when it is not sound, your body is full of darkness. ³⁵ Therefore be careful lest the light in you be darkness. ³⁶ If then your whole body is full of light, having no part dark, it will be wholly bright, as when a lamp with its rays gives you light.”
