Let the Light In: Week Three Study Guide

In week three of “Let the Light In,” a special, four-week Christmas study, we’ll discover the power of the light of Jesus in our lives and world!

Memory Verse of the Week: 1 John 1:5 (NIV)

“This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all.”

Something to Think About: Did you know that an estimated 11 percent of the adult U.S. population is afraid of the dark? According to author Cari Romm, “The dark leaves us vulnerable and exposed, unable to spot any threats that may be lurking nearby.” 

The truth is this fallen world is full of dark corners, constantly threatening to cover us in fear-inducing darkness. At times, life can feel like we’re walking around blindfolded. This is why so many people walk around lost, trapped, and/or crippled by anxiety and fear. But all those who trust in Jesus don’t have to fear the dark. Why? Because GOD IS LIGHT, and no shadow of darkness can exist in him.

Everything in Him, everything about Him, everything He pours into us, and everything He gives to us is full of light. Theologian Joseph Barnes wrote, “Light, in the Scriptures, is the emblem of purity, truth, knowledge, prosperity, and happiness—as darkness is of the opposite. John here says that ‘God is light’—φῶς phōs—not the light, or a light, but light itself; that is, He is Himself all light and is the source and fountain of light in all worlds.” 

In John 1:4–5, 9–12 (NIV), we’re told, “In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it. . . . The true light that gives light to everyone was coming into the world. He was in the world, and though the world was made through him, the world did not recognize him. He came to that which was his own, but his own did not receive him. Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God.” And then in John 8:12 (NLT, emphasis added), Jesus declares to us, “I am the light of the world. If you follow me, you won’t have to walk in darkness, because you will have the light that leads to life.” Friends, this is what Christmas is! It’s the arrival of the brilliant light that breaks through the darkness in our world and in our lives and illuminates our hearts. 

And so, as we draw nearer to Him each day, as we have fellowship with Him (1 John 1:3–4) and become more like Him, we will be able to walk in the light (1 John 1:7) regardless of what’s going on around us. As the Lord shines brilliantly into the most pitch-black corners of the world, we will see clearly if we keep our gaze fixed on Jesus, the marvelous light. 

What can we learn about Jesus as the light of the world from the Christmas story?

  • In a battle between light and darkness, light always wins.
  • Light gives life.
  • Light reveals truth.
  • Light brings joy.

Discussion Question 1: What does creation reveal about the light of Christ? How have you seen His light shine in your life or the lives of those around you this year?

Let the Light Shine: There are many people who are lost and in darkness. As His ambassadors, we’re called to shine the light of Christ  (Matthew 5:14–16). God wants to use us to cast out darkness and bring people into His light. He wants to bring life and hope into the hearts of those who don’t yet know Him. Let’s do all we can to shine God’s light and not keep it hidden!

Discussion Question 2: What steps can you take this week to help others in your community and sphere of influence to let the light of Jesus into their lives?


Spend time praying this week for the Lord to reveal what He wants to do in your life this Christmas!


In our next study, we’ll conclude our special look at the Christmas story as we learn how to let the light of Jesus in!
