Luke 11:34-36

Lamsa(i) 34 The lamp of your body is your eye; when therefore your eye is clear, your whole body will also be lighted; but if it is diseased, your whole body will also be dark. 35 Take heed, therefore, lest the light which is in you be darkness. 36 If your whole body is lighted, and there is no part in it dark, the whole of it will give light, just as a lamp gives you light with its shining.
