God is light. We hear this all the time as part of our normal “Christian-ese.” Even people who aren’t believers say things during others’ hard times, such as “sending you love and light” and “sending light your way.” But there is one true source of all light. What IS this light and how powerful is it?

God is the light to our world and our spirits. He is LIVING breathing that is self-powered so that no darkness can overcome it. Darkness has no place to go in the presence of this light. As humans who have yet to experience heaven, we cannot fully comprehend God’s light, as we are limited by our earthly understanding, but it is a light that conquers all sin and darkness.

When we think of light, we may think of the burning star that lights our planet daily (the Sun), or a lightbulb where the light is conducted through electricity. You may even think of a fire or a candle. God’s light is so powerful that it exists all on its own as a living light. It conquers all evil and darkness because God’s light emits from His own power, His own goodness, and His own holiness. God Himself is the light.

Revelation 21:23-24, CSB says a day is coming where: “The city does not need the moon or the sun to shine on it, because the glory of God illuminates it, and its lamp is the Lamb. The nations will walk by its light, and the kings of the earth will bring their glory into it.” It is so powerful that it has conquered the works of Satan and the evil that wreaks havoc on earth, as we have been shown by Jesus when He walked the earth.

There are several powerful examples of how Jesus conquered darkness throughout the Bible. John 1:1-5, CSB tells us that in the beginning was the Word and the Word was LIGHT. And Genesis 1:2-4, CSB tells us: “Now the earth was formless and empty, darkness covered the surface of the watery depths, and the Spirit of God was hovering over the surface of the waters. Then God said, ‘Let there be light,’ and there was light. God saw that the light was good, and God separated the light from the darkness.”

God’s Word alone was the light and provided the light. On day one of earth’s conception, God separated light from darkness, and since then, these two concepts cannot co-exist. Where light is, darkness may not prevail.

The most poignant example, of course, is Jesus’ death and His miracle resurrection. This is the defining event of our Christian faith. After Jesus was brutally mocked and murdered and left to die, darkness covered the land for three hours… in the middle of the day!

I can imagine people slowly and solemnly sauntering away from the scene of the crosses. Maybe they were sad that this beautiful age of Jesus walking with them was over. There would be no more healing, no more teachings, and no more miracles. (Or so they thought!) Maybe they began wondering if He truly was the Son of God.

But then, three days later, to everyone’s surprise, Jesus rose from death. He rose from the darkest and most permanent state a human body can experience—the death of the body. He took on ALL sin. ALL darkness. ALL hopelessness. And then made a mockery of death in His resurrection.

We are all invited to participate in this power through the Holy Spirit. John 12:31-33, CSB, says, Jesus’ death and resurrection defeated the powers of darkness that controlled the world. We are all invited to live in the light of Jesus. Jesus’ light is not only a physical shining light but our spiritual light, our guiding light when we feel darkness all around us. He is our hope for a future and the overcoming of our sins.

How can we show this eternal light to others? How can we be this light for others through the authority given to us by Christ? We do not need to worry because this is not in our power but through Him alone!
