Let Your Light Shine
Day 247 – 4 September
The Light That Becomes Life
I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life. (John 8:12, ESV)
How a Leaf Makes Life
On a bright morning, every green leaf in the garden is at work, performing a piece of chemistry so fundamental that almost everything alive depends on it. Inside each leaf sits a pigment called chlorophyll, the very thing that makes the leaf green, and its single job is to catch sunlight. What the leaf does next is close to miraculous. It takes that captured light, together with water drawn up from the roots and a colourless gas pulled from the air, and it builds sugar, the plain fuel of living things. Light goes in; life comes out. A plant, after all, eats nothing; it makes its own food out of sunshine, and the sugar it builds becomes the first link in a chain that feeds the grazing animal, and the creature that eats the grazing animal, and finally us. Nearly every meal on earth began as light that a leaf turned into life. And the moment the light fails, the whole process halts; a plant kept in the dark starves in the middle of plenty, surrounded by air and water it can no longer use. That leaf, turning light into life, is the picture behind an astonishing promise Jesus makes.
The Light of Life
On the morning after He had refused to condemn a woman dragged before Him, Jesus stood in the temple and made the second of His great declarations: “I am the light of the world” (John 8:12). We met that title earlier in the week, the audacious claim of the One who is light for the whole human race. Yet He never stops at seeing. He goes on: “Whoever follows me will not walk in darkness, but will have the light of life.” That closing phrase is the treasure. In Greek it is τὸ φῶς τῆς ζωῆς (to phōs tēs zōēs, the light of life), and the small word ζωή (zōē, life) is doing something the English can flatten. This is no bare survival, no ticking-over existence; ζωή (zōē, life) is John’s chosen word for the life that comes from God Himself, the life of the age to come, life bound up with knowing Him. And the way the phrase is built repays a moment’s attention. “The light of life” follows a Hebrew habit of speech in which the second word names what the first one produces, so the sense, as one of the Reformers spelt it out long ago, is the life-giving light. The light Jesus gives is no cold lamp you merely read by. It does in the soul what sunlight does in a leaf: it makes life. Follow Him, and His light starts turning into life inside you.
Only by Following
The promise hangs on a single word, and it keeps us from a familiar mistake. The one who has the light of life is “whoever follows me.” The verb Jesus uses for following is a present, continuous one; it paints a way of walking kept up over time, never a single step taken once and left behind. To follow Him, the old writers agreed, simply means to trust Him, to keep company with Him, to go where He goes. And the light of life is promised as the settled result of that following: “shall have,” He says, a real and inward possession, held for keeps. This is worth pressing, because we are quick to imagine that the life must be earned, that we manufacture it by trying harder and glowing brighter. The leaf corrects us. A leaf earns nothing from the sun; it simply stays in the light, turned towards it, open to it, and the light does the rest, building life inside the green. So it is with the follower. You keep company with the Light, you stay turned towards Him, and He does in you what you could never do for yourself. The life is His gift, worked in everyone who follows and withheld from no one who comes.
Turned Towards the Light on a Friday
This means the day in front of you is less about effort than about direction. The question for an ordinary Friday is a simple one: am I staying turned towards Him? A follower keeps close through the plainest things, a few minutes given to Him before the rush begins, a silent word turned His way in the queue or the traffic, a choice made His way when an easier road opens. None of that is you generating life by willpower; it is you staying in the light, like the leaf, so the light can go on making life in you. And it will show, slowly and surely, the way health shows in a well-fed plant: a patience that was thin last year running a little deeper, a kindness that comes more readily, a peace that holds when the day tries to rattle it. That is the life of God, steadily rising in a person who keeps following. So when this Friday offers you a hundred small chances to turn away or to stay near, keep turning towards the Light, and let Him do in you what the morning sun is doing in every leaf outside your window.
Declaration
The light I follow is doing more than showing me the way; it is turning into life inside me. I could no more manufacture that life than a leaf could invent the sun. My part is small and steady: to stay turned towards the One I follow, to keep close, to walk where the light leads. So I will let go of the tiring idea that I must glow by my own effort, and I will simply remain in the light, open and facing it, the way green things lean towards the morning. The life given here is a gift held for keeps, offered to me and to everyone else who comes, kept back from no one. Today I will keep following, through the small turns and the plain choices, trusting that the light I walk by is becoming life in me even when I cannot feel it working. Let me stay in it, and let it do what only light can do.
