Lord, I pray that you may be a lamp for me in the darkness.
Touch my soul and kindle a fire within it,
that it may burn brightly and give light to my life.
Thus my body may truly become your temple,
lit by your perpetual flame burning on the altar of my heart.
And may the light within me shine on my brethren
that it may drive away the darkness of ignorance and sin from them also.
Thus together let us be lights to the world,
manifesting the bright beauty of your gospel to all around us.
Columbanus, 543 – 615, Irish missionary, founded monasteries in France and Italy

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.
