Lk 11:33-36

The Simile of Light. 33“No one who lights a lamp hides it away or places it [under a bushel basket], but on a lampstand so that those who enter might see the light.^q 34The lamp of the body is your eye.^r When your eye is sound, then your whole body is filled with light, but when it is bad, then your body is in darkness. 35Take care, then, that the light in you not become darkness. 36If your whole body is full of light, and no part of it is in darkness, then it will be as full of light as a lamp illuminating you with its brightness.”
