“No one lights a lamp and puts it in a place where it will be hidden, or under a bowl. Instead they put it on its stand, so that those who come in may see the light.
Your eye is the lamp of your body. When your eyes are healthy,your whole body also is full of light. But when they are unhealthy,your body also is full of darkness.
See to it, then, that the light within you is not darkness.
Therefore, if your whole body is full of light, and no part of it dark, it will be just as full of light as when a lamp shines its light on you.”
