No one, when he has lit a lamp, puts it in a secret place or under a basket, but on a lamp stand, that those who come in may see the light. The lamp of the body is the eye. Therefore, when your eye is good, your whole body also is full of light. But when your eye is bad, your body also is full of darkness. Therefore take heed that the light which is in you is not darkness. If then your whole body is full of light, having no part dark, the whole body will be full of light, as when the bright shining of a lamp gives you light.
He begins the story of the lamp by saying in effect, "I have the light of God. I must show it to others as that is what God wants me to do. I will be deterred from doing this work because some men are against it and call it evil."
