“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.”
As Jesus continues His discussion, He once again uses the metaphor of light and a lamp to illustrate the condition of a person’s heart. Make no mistake; when the Pharisees attributed His driving out of demons to the work of the devil, they showed how corrupt their hearts had become. When someone demanded a sign, they also revealed a darkened heart.
Jesus illustrates with a proverb in 11:33 in which a lamp is used to illustrate His point. You don’t hide the light from a lamp; you put it on its stand so that everyone can benefit from the light. From there, He moves on with His metaphor; your eye is the lamp of your body. It is the organ that allows light to enter, a fact science has verified, by the way. As long as your eyes are healthy, you can see things clearly because light has entered and been understood. Yet if our eyes are not healthy, this process doesn’t work properly, and we cannot see the environment around us.
In verse 35, Jesus uses an imperative: “See to it…” that we allow His light to enter through our eyes, reminding us of something He often says: “Let he who has eyes to see…” When we insist that we see the truth, our entire beings will be filled with His light, and our hearts will be hearts that seek the truth and not the lie of the prince of darkness.
With this, Jesus concludes His remarks. Afterwards, He receives a curious invitation…
