"But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin."
1 John 1:7 (ESV)
Week 2 of 4
Preparation This Week
On the second Sunday of Advent, hang lights on your bare tree — white or clear lights are especially meaningful, though any colour works. Do not add ornaments yet. Let the lit tree stand alone for the week: tree and light, nothing more. The lights themselves are the message.
Think about how most families decorate their tree. The lights go on first — and then, within minutes, they disappear under layers of ornaments, tinsel, and ribbon. We step back and admire the finished product, but the lights themselves are buried. They are still there, glowing behind everything else, but no one is looking at them anymore.
It is a small parable. Many of us treat the light of God in our lives the same way. We pile on activity, entertainment, comfort, ambition — even good things, important things — until the light that was supposed to be the foundation of everything becomes invisible. Not extinguished. Just covered. We have stopped seeing it.
This week, your tree will not let you do that. There are no ornaments to hide behind. There is only the bare tree from last week — and now, light. Look at it. Sit with your family in a darkened room and let the tree glow. What you are seeing is a picture of the gospel.
"God said, 'Let there be light' — and there was light. Before the sun. Before the stars. Before anything else existed. Light came first."
Advent Christmas Tree Devotional
Light Before All Things
When God created the universe, the very first thing He made was light (Genesis 1:3). Not the sun — that came on the fourth day. Not the stars or the moon. Light itself, called into existence by the voice of God, preceding and undergirding everything that would follow. This is not a scientific puzzle to be solved. It is a theological declaration: God is the source of all light. He does not depend on anything He has made. He is the light, and "in him is no darkness at all" (1 John 1:5).
But darkness is real. The Bible does not pretend otherwise. Job sat in ashes and cursed the day he was born, longing for a darkness so complete that not even God would look for him (Job 3). The psalmist cried out from the pit, "Darkness is my closest friend" (Psalm 88:18). The people of Israel walked in literal darkness during the exile — centuries of silence, oppression, and waiting. Darkness is what the world looks like when the light is hidden.
Into that darkness, the prophets spoke. Isaiah declared, "The people who walked in darkness have seen a great light" (Isaiah 9:2). He promised that God would send His servant as "a light for the nations, to open the eyes that are blind" (Isaiah 42:6-7). And Malachi, the last prophetic voice before four hundred years of silence, ended with a promise: "The sun of righteousness shall rise with healing in its wings" (Malachi 4:2).
Then the silence fell. Four centuries. No prophet. No word. No sign. And then — a baby, born at night, in a stable, in an occupied backwater of the Roman Empire. Angels appeared to shepherds in the dark, and "the glory of the Lord shone around them" (Luke 2:9). The light had come. Not as the world expected. Not with armies or spectacle. But as a child, wrapped in cloths, laid in a feeding trough.
John's Gospel opens not with the manger but with the meaning behind it: "In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it" (John 1:4-5). This is the claim of Christmas. The light is not a metaphor. It is a person. And the darkness — all of it, every kind, from Eden's exile to your worst night — has not overcome it.
Your Tree in the Darkness
The lights on your tree this week are not decorations. They are a confession. They say: we believe that the light has come. We believe that the darkness does not win. We believe that the God who said "Let there be light" before anything else existed has sent His own Son as the true Light into the world — and that "whoever follows me will not walk in darkness, but will have the light of life" (John 8:12).
But the Bible is honest about light in a way that should unsettle us. Jesus said, "The light has come into the world, and people loved the darkness rather than the light" (John 3:19). The light is here. The question is whether we will step into it — or whether we prefer the comfort of the dark. Walking in the light means walking in truth, in confession, in fellowship (1 John 1:7). It means being seen. That is harder than it sounds.
The readings below trace the thread of light through the whole Bible — from God's first creative act, through the darkest laments, through the psalms that cry out for illumination, through the prophets who promised dawn was coming, to the night when the Light entered the world as a baby, and forward to the city where God Himself will be our light and night will be no more. As you read, sit near the tree. Let the glow remind you what you are reading about.
Study Guide
Four sessions for the family — one for the Sunday gathering, three for the days of the week. Each session ends with reflection questions. Times are guides, not timers.
Session 1 — Sunday Gathering ~20 min
Light Before All Else
Hang the lights, then sit in the glow with the room dark and read where the Bible's whole story of light begins — before there was a sun, a moon, or a single star.
"Let There Be Light"
Genesis 1:1–5God's first act of creation — light called into existence by His voice, before the sun, moon, or stars exist.
Genesis 1:14–19God creates the sun, moon, and stars on the fourth day — the lights of the sky serve a Light that was already there.
Reflect
The first thing God made was not a star or a sun, but light itself. What is the Bible telling us about God when it makes light come before the things that produce it?
Light is the only thing God called "good" before there was anyone to see it. Why does that matter when you feel like no one is watching the small good things you are doing?
Look at the lights on your tree. Before any ornament, any gift, any other thing of Christmas — there is just light. How does that match the way the Bible begins?
The Light Behind the Lights
Psalm 19:1–6The heavens declare the glory of God — even the sun, "like a bridegroom leaving his chamber," is a witness, not the source.
Isaiah 45:5–7"I form light and create darkness" — the one God who rules both, with no rival.
2 Corinthians 4:1–6"God, who said 'Let light shine out of darkness,' has shone in our hearts" — the same word that began creation begins the Christian.
Reflect
The same voice that said "let there be light" in Genesis 1 is the voice Paul says has shone in the heart of every believer. What does that mean for the small flicker of faith you sometimes feel?
Isaiah 45 says God forms both light and darkness. How is that a comfort and not a threat?
Close in prayer. Thank God that the same God who first said "let there be light" still speaks light into our darkness.
Session 2 — Weekday ~45 min
Darkness and the Cry for Light
The Bible is honest about darkness — plagues, laments, and dark nights of the soul. Before we read the promise of light, we sit with the people who longed for it.
When Darkness Falls
Exodus 10:21–29The plague of darkness over Egypt — three days so thick it could be felt, yet Israel had light in their dwellings.
Job 3:1–26Job laments in darkness — a man who has lost everything and wishes the day of his birth had been swallowed by night.
Psalm 88"Darkness is my closest friend" — the Bible's darkest psalm, a cry from someone who sees no light at all.
Lamentations 3:1–26"He has driven and brought me into darkness without any light" — and yet, "the steadfast love of the Lord never ceases; his mercies are new every morning."
Reflect
God did not edit the darkness out of the Bible — He kept Job, Psalm 88, and Lamentations in. Why is it important that Scripture has space for the people who feel no light?
Lamentations sits in pitch darkness for twenty verses — and then turns on the words "But this I call to mind, and therefore I have hope." Where in your week do you most need to make that turn?
In Egypt, Israel had light in their homes while darkness covered the land. What does it mean that God can keep light burning in a household even while everything around it is dark?
"The Lord Is My Light"
Psalm 27:1–6"The Lord is my light and my salvation — whom shall I fear?" — confidence sung in the dark.
Reflect
David sings "the Lord is my light" — present tense — while in the same psalm asking God to hide him from his enemies (v. 5). What does it mean to call the Lord your light before the darkness lifts, not after?
David is not denying the darkness around him — he is naming the Lord as a brighter reality. What would it look like for you to do the same this week?
Close in prayer. Pray for someone in your life who is sitting in a darkness like Job's or Psalm 88.
Session 3 — Weekday ~25 min
The Light Promised, the Light Arrives
For centuries the prophets promised dawn was coming. Then four hundred years of silence — and then the Word became flesh, the Light entering the world He had made.
The Promise of Dawn
Isaiah 9:1–7"The people walking in darkness have seen a great light" — the promised Prince of Peace.
Isaiah 42:5–9"I will give you as a light for the nations, to open the eyes that are blind" — the Servant's mission.
Malachi 4:1–6"The sun of righteousness shall rise with healing in its wings" — the last promise before four centuries of silence.
Reflect
Isaiah promised "a great light" to people walking in darkness. Note that he says walking, not standing still. What does it look like to keep walking when you cannot see what's ahead?
Malachi was the last word from God for four hundred years. What might it have been like to be a faithful Israelite in that long silence — and what comfort do you draw from knowing God was not absent in it?
The Light Made Flesh
John 1:1–18"In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it."
Reflect
John says the light shines in the darkness and the darkness has not overcome it. Where in your life right now do you most need to hear that the darkness has not won?
The Word "became flesh and dwelt among us" — the Light is not a concept, but a person. Why does that matter when you most need light?
Sit quietly with only your tree lights on. Read John 1:1–5 again, slowly. What do those familiar words sound like in the dark?
Close in prayer. Thank God that He did not leave us in the dark.
Session 4 — Weekday ~30 min
The Light Embraced — and the Eternal Day
The Light has come — but a light demands a response. We close this week looking at what it means to walk in the light, and at the city where God Himself will be the light forever.
"I Am the Light of the World"
John 8:12–20"I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life."
Reflect
Jesus does not say "I will show you light." He says, "I am the light." What is the difference between trying to find light and following the One who is light?
The light is meant to be followed, not just admired. Where in your life is Jesus calling you to take a next step in His light?
Walking as Children of Light
Matthew 5:14–16"You are the light of the world. A city set on a hill cannot be hidden" — Jesus tells His followers they carry the light.
Ephesians 5:8–14"You were once darkness, but now you are light in the Lord. Walk as children of light."
1 John 1:5–10"God is light, and in him is no darkness at all" — walking in the light means walking in truth and fellowship.
Reflect
Jesus says "you are the light of the world" — present tense, before they had done anything. What does that change about how you understand your role at home, at work, or at school?
1 John says walking in the light means honest fellowship and confession, not flawlessness. What hidden thing might it be time to bring into the light this Advent?
No More Night
Revelation 21:22–27"The city has no need of sun or moon to shine on it, for the glory of God gives it light" — the new Jerusalem, where God Himself is the lamp.
Reflect
The Bible begins with God saying "let there be light" and ends with God Himself being the light. What is gained by reading those two scenes together?
The new city has no temple, no sun, no moon — only God. If you took that promise seriously this week, what fear or grief would loosen its grip on you?
Look once more at the tree, lit and bare, no ornaments yet. The lights point to the Light. How will you keep seeing the lights — really seeing them — when the ornaments go on next week?
Close in prayer. Thank God for the day that is coming when the lights on the tree will no longer be needed.
