Day 12 — What Fills My Mind

“The eye is the lamp of the body. If your eyes are good, your whole body will be full of light. But if your eyes are bad, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness!”

— Matthew 6:22–23 (BSB)

Try an experiment. Sit somewhere for five minutes with nothing: no phone, no music, nobody to talk to. For a lot of us, by about the second minute, a hand is already reaching for a pocket. We have become people who are almost never alone with our own thoughts.

Blaise Pascal, a brilliant French mathematician who became a devoted Christian, noticed this in the 1600s, long before electricity. He wrote that “all the unhappiness of men arises from one single fact, that they cannot stay quietly in their own chamber.” He watched people fill every hour with games, hunting, gossip and noise. Why? Not because those things made them happy, but because if they stopped, they would have to think about the big questions. Who am I? Where am I going? What happens when I die? Diversion, he said, keeps those questions away. Pascal would recognise the endless scroll instantly.

Jesus said, “The eye is the lamp of the body.” What you let in through your eyes doesn’t just pass through. It fills you with light, or it fills you with darkness. In Jesus’ day, a “good” eye meant a healthy, clear eye that was focused on one thing, and a generous one too. A “bad” eye was clouded and greedy. What you keep looking at shapes what you love, what you want and what you worry about.

That’s true of content that’s obviously harmful, and you probably know where your own lines are. But it’s also true of the ordinary flood: hundreds of short clips a day, each a few seconds long, each pulling you to feel something. Laugh. Envy. Fear. Outrage. Want. None of it may be wicked. But a mind fed only on fragments slowly loses the ability to stay with anything. Reading a long chapter gets harder. Praying for more than a minute feels impossible. Even a real conversation starts to feel slow.

Your attention is one of the most valuable things you own. Companies pay huge sums to buy it. God asks for it too, but not to sell it. He wants it because He wants you.

Paul gives a filter: “whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think on these things.” That isn’t a list of banned things. It’s a menu. Fill up on what’s on it, and there’s less room for the rest.

A few ways to win your attention back:

• Practise being bored. Wait for the bus, stand in a queue, walk to school without filling the silence. Boredom is where thinking, noticing and praying often begin.
• Do one thing at a time. Homework without a video in the corner. A meal without a screen. Notice how much more you see.
• Read something long. A book, or a whole Gospel in one sitting. It trains a muscle that scrolling has let go weak.
• Meet God in the quiet. “Be still and know that I am God.” Stillness isn’t empty. It’s where God is often heard.

The light in you is meant to burn steadily, not flicker with every new thing that crosses a screen.

Think about it: When were you last alone with your thoughts, with nothing to fill the silence? What did it feel like, and what did you start to think about?

Try this: Do one ordinary thing today with no screen at all: a walk, a meal or a journey. Use the quiet to talk to God about whatever comes to mind.

Go deeper: Pensées by Blaise Pascal — in his notes on “diversion,” Pascal argues that we chase endless amusement because we can’t bear to sit still and face what we really are, and that even a king left with nothing to distract him is miserable. Start with chapter 2, “The Misery of Man Without God”.

Father, my mind is so full of noise that I hardly hear myself, let alone You. Make my eye clear and my heart steady. Teach me to fill my mind with what is true, right and lovely, and to be still long enough to know that You are God. In Jesus’ name, Amen.
