Luke 11:33–36

No man lighteth a candle and putteth it in a hidden place, nor under a bushel: but upon a candlestick, that they that come in may see the light. 34The light of thy body is thy eye. If thy eye be single, thy whole body will be lightsome: but if it be evil, thy body also will be darksome. 35Take heed therefore that the light which is in thee be not darkness. 36If then thy whole body be lightsome, having no part of darkness: the whole shall be lightsome and, as a bright lamp, shall enlighten thee.
