Growing up, I heard a saying often attributed to Sir Isaac Newton which say, "Energy is not lost or destroyed, it is merely transferred from one party to the next".
It helped explain something I had seen in real life long before I had an explanation for it. One person could walk into a room carrying anger, bitterness, jealousy, or fear, and before long, the atmosphere would shift. A harsh comment would become another harsh comment. Someone’s frustration would become everyone’s tension. A private mood would become a shared weight.
At first, I only thought about that saying in terms of relationships. But the older I get, the more I realize the same principle can apply to what we watch, hear, scroll through, laugh at, and meditate on.
What enters our minds does not always stay at the surface.
A song can stir an old desire. A show can normalize a certain way of thinking. A social media feed can leave us restless and dissatisfied. A movie can make sin look beautiful. A stream of outrage can train us to live angry. Even when we call it entertainment, the things we repeatedly give our attention to can quietly begin shaping what we desire.
And what we desire often shapes what we pursue.
Scripture never treats the heart as untouched by influence. Proverbs says:
“Keep thy heart with all diligence; for out of it are the issues of life.”
— Proverbs 4:23, KJV
That verse tells us to guard our hearts diligently. The heart is where desire, thought, motive, worship, and direction meet. What settles there eventually shows up in our words, choices, relationships, and habits.
This is why discernment matters. The point is not to treat every movie, song, book, joke, or cultural moment as something to fear. The deeper concern is that our hearts are impressionable. We do not stand outside culture untouched by it; what we continually watch, hear, and dwell on has a way of shaping what we love, desire, and who we are becoming.
Many of us turn to entertainment because we are tired. I get it, I do the same thing. After a long day, we want to unwind. After a stressful week, we need an escape. There is nothing wrong with rest, laughter, beauty, creativity, or storytelling. These can be gifts from God when received with wisdom. The danger comes when entertainment becomes the main place where our minds rest, our emotions are fed, and our desires are trained.
Jesus said:
“For where your treasure is, there will your heart be also.”
— Matthew 6:21, KJV
Our hearts tend to follow what we treasure. What we admire often pulls us closer. What we repeatedly watch can begin to feel normal. What we normalize can become easier to excuse. Before long, something that once troubled us may begin to entertain us.
This is why it is important to ask better questions. Instead of only asking, “Is this a sin?” we can ask, “How is this forming in me?” “What does this make me want?” “Does this help me love what God loves?” “Does this make obedience feel clearer or harder?”
Those are not legalistic questions. They are discipleship questions.
The psalmist wrote:
“I will set no wicked thing before mine eyes.”
— Psalm 101:3, KJV
That is not a call to hide from the world. As Christians, we are not called to live with our eyes closed, pretending culture does not exist. We are called to live in the world as people who belong to Christ. Discernment does not mean we avoid certain things to prove we are holy. It means love for God teaches us to walk wisely, guard our hearts, and pay attention to what is shaping our desires.
Some content simply does not need repeated access to our eyes, minds, or hearts. That is not weakness. It is wisdom.
When Christians hear the word “meditation,” we often think of Scripture reading, prayer, worship, or quiet reflection. But meditation is also whatever we return to again and again in our minds. It is what we replay, rehearse, imagine, and dwell on when no one else is around.
Psalm 1 says of the blessed person:
“But his delight is in the law of the Lord; and in his law doth he meditate day and night.”
— Psalm 1:2, KJV
Biblical meditation fills the mind with truth. It allows God’s Word to shape our thinking until our desires begin to come under His authority. Yet the opposite can also happen. A person can meditate on bitterness by replaying old offenses. Lust can be strengthened by returning to certain images. Fear can grow through constant anxiety-driven content. Envy can deepen through endless comparison. Anger can feel righteous when outrage becomes our daily diet.
Paul writes:
“Be not conformed to this world: but be ye transformed by the renewing of your mind.”
— Romans 12:2, KJV
The world often conforms us through repetition. God transforms us through renewal. That means our minds are not spiritually neutral spaces. They are places of formation.
This is how the culture shapes our worldview without us realizing it. It simply gives us stories, images, jokes, trends, songs, and personalities to admire. Over time, those messages can teach us what success looks like, what love should feel like, what beauty is, what freedom means, and what desires deserve to be followed.
Paul gives believers a better framework:
“Whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report… think on these things.”
— Philippians 4:8, KJV
This does not mean Christians can only watch or read things that are cheerful or simple. Scripture itself tells stories involving betrayal, grief, injustice, violence, temptation, and failure. The deeper question is how darkness is being portrayed. Is sin exposed honestly, or is it glamorized? Does the story awaken wisdom, compassion, courage, and repentance, or does it numb the conscience?
Not everything we are free to consume will build us up.
Paul writes:
“All things are lawful for me, but all things edify not.”
— 1 Corinthians 10:23, KJV
Christian freedom is not permission to be careless. It is the freedom to love God wisely. A mature believer does not only ask, “Can I watch this?” Sometimes the more honest question is, “What is watching this doing in me?”
James describes how temptation works:
“Every man is tempted, when he is drawn away of his own lust, and enticed. Then when lust hath conceived, it bringeth forth sin.”
— James 1:14–15, KJV
Desire is spiritual. It can be cultivated, strengthened, weakened, inflamed, or surrendered. A steady diet of greed can make contentment harder. Constant lustful content can make purity harder. Daily outrage can make gentleness harder. Endless comparison can make gratitude harder. Cynicism can slowly make hope feel foolish.
Entertainment may not have power on its own, but what we repeatedly give our attention to can begin to shape us. The songs, stories, images, and messages we return to can slowly influence what we love, what we desire, and what feels acceptable to us. Because we are worshiping and habit-forming people, what we behold again and again often settles deeper than we expect.
Discernment is not about fear. It is about love. We do not guard our hearts because we think God wants to take joy away from us. We guard them because our desires matter to Him. Holiness is not deprivation; it is freedom from being ruled by lesser things.
Entertainment has a place, but it should not have the throne. When it becomes our primary comfort, teacher, escape, companion, and source of identity, it begins functioning like a spiritual authority. It tells us what to admire, what to fear, what to envy, what to excuse, and who to become.
But Christians belong to Christ.
Paul writes:
“Ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.”
— 1 Corinthians 6:20, KJV
Our eyes belong to Christ. Our ears, minds, imaginations, desires, and entertainment choices belong under His lordship too.
The good news is that we are not stuck with disordered desires. Our minds can be renewed. Our hearts can be guarded. Our imaginations can be healed. Our loves can be reordered.
Second Corinthians says:
“But we all… beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory.”
— 2 Corinthians 3:18, KJV
We are changed by beholding. That is the deeper invitation. The Christian life is not only about turning away from what harms the soul. It is about turning our eyes toward Christ until His beauty becomes greater than the world’s imitation of beauty.
What we entertain can shape what we desire. What we meditate on can influence what we become. So the question is worth asking with honesty and grace: What is forming me right now?
Whatever has our attention is not always neutral. And no one is more worthy of our attention than Jesus.
