Do you know why we're called to be a light in the darkness?
"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." (John 1:4-5)
In the gospel, the world is described as spiritually dark; full of sin, confusion, despair, separation from God, and evil. Darkness represents ignorance, and moral blindness. "The World" literally cannot see the light.
The unbelieving world is enveloped in this deep spiritual darkness; not just dim or shadowy, but actively unable to perceive or receive the light of Christ. Not for a mere lack of information, but because of a hardness of heart. And it's caused by a spiritual possession.
2 Corinthians 4:4
"In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God."
Satan is actively blinding unbelievers’ minds, to prevent them from seeing the illuminating truth of the gospel. It’s why the gospel can seem "veiled" or hidden to many folks. Not because the message is unclear, but because their perception has been obstructed.
John 1:5
"The Light shines in the darkness, and the darkness has not overpowered [understood] it."
Why though really?
Why can't "the dark" understand the gospel?
How is that Satan has accomplished this deed?
The simple answer is, there's a built-in preference for darkness over light.
John 3:19-20
"And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil."
Why can’t the dark understand?
Because understanding would demand exposure and change. And even when that light is shining directly onto someone, it can illuminate and even warm that soul (which is really just information being received), but the flesh that carries it doesn't receive that light. In fact, the flesh stands between the light and the shadow that is cast behind it.
In that shadow is the truth. The truth of who they are. There's no light in that shadow. And that's because the flesh stands between the light and that true-self.
The "built-in preference" for darkness isn’t just passive ignorance; it’s an active, heart-level love for it, rooted in the fear of exposure and the resistance to transformation. The true self is revealed in stark, unflattering reality. Which is why so many vehemently lash out at the light. They in fact prefer darkness because stepping into the light would force confrontation with their evil deeds; exposure that demands repentance, surrender, and change. They'd have to justify their actions to themselves, not just God. They'd have to live with it. Their unregenerate heart recoils because it clings to autonomy and self-justification. Which is a wordy way of saying, they're lying to themselves.
The apostle Paul describes this situation, this internal war:
Romans 7:18-23
"For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out...So I find it to be a law that when I want to do right, evil lies close at hand."
This is a man following after God's Son. Imagine the state of the soul that isn't.
Their flesh is warring against the mind’s desire for God, blocking full obedience and understanding. Even when light shines (the law revealing their sin, or the gospel calls), the flesh resists because it loves its own way. Their flesh is actively opposing the Spirit’s illuminating work, creating a shadow where truth about the self is hidden or distorted.
BUT!
This isn't the end of their story...
Right after the apostles cry comes the answer in verse 25:
"Thanks be to God, through Jesus Christ our Lord!"
This is the breakthrough. The deliverance isn’t from better willpower, clearer arguments, or moral bootstrapping. It’s through Jesus Christ; His perfect life, and His atoning death that condemned sin in the flesh.
His resurrection power!
And His return!
The story isn’t over because God is not done.
The preference for darkness is strong, the flesh is fierce in resistance, BUT GOD!
Christ’s victory is stronger!
He covers them with His righteousness, and regenerates the heart by giving them a new one (Ezekiel 36:26).
This is why our calling as lights matters so much. We shine not to shame or condemn, but to point to the source of that light who is saying to them, "Come out of the shadow...I’ve already overcome the darkness for you."
What seems impossible, seems to hard to comprehend, the facing of one's true self without despair, is nothing compared to what Christ has prepared for them. The shadow that once hid the broken, sinful reality isn’t the final word. Christ Himself steps into it, takes the full weight of exposure and judgment, and then flings open the door to something infinitely better; freedom, forgiveness, new life, and a future so bright it makes the old darkness seem like a fleeting nightmare.
Think of it this way: The unregenerate heart recoils at the light because it fears the truth will destroy it. But Jesus doesn’t come to destroy the person; He comes to destroy the power of sin and death that enslaves them (Hebrews 2:14-15).
So here's what you do, turn around for a second and look at your shadow. Face the shadow and understand it for all it's worth. Then try and imagine you apart from it.
Now listen to what Jesus is saying:
"I’ve already borne that wretchedness on the cross."
"Now come out; I’ve already prepared a place for you where there’s no more shadow, no more war within, only light and life forever."
And just do it!
Turn away from that shadow and face the light.
And then step into it...
And the beautiful part?
You don’t have to muster up perfect faith or clean up first. You just turn. You just take that first step.
And I'll be praying for you to finish well.
Amen?
Amen! 🙏🏼
