What You Feed Your Mind You Feed Your Soul
Guard What Feeds the Soul: Why Music and Media Are Not Spiritually Neutral
Music and media shape more than a mood. They train attention, stir affection, reinforce values, and influence spiritual sensitivity. In this message, Dr. Perry Greene explains why Christians must think carefully about what they allow into their minds, how worship songs can teach biblical truth, and why everyday entertainment can either strengthen faith or slowly corrode it.
Music has a strange power over people. A melody can bring back a memory, settle a troubled heart, deepen conviction, or carry a message long after spoken words have faded. Dr. Perry Greene opens this GodNAmerica message by pointing to a Sunday broadcast from the BBC, when a service from the Keswick Convention in the English Lake District included worship led by modern hymn writer Stuart Townend. Among the songs was "In Christ Alone," one of Townend's best-known hymns.
Before leading the congregation, Townend spoke briefly about the significance of singing in worship. Dr. Greene notes that Townend emphasized the teaching function of songs and their ability to help believers express their feelings and emotions to God. He also observed, with some humor, that people are often more likely to leave church singing the songs than reciting the sermon. Dr. Greene is careful to explain that this was not a criticism of Sunday preaching. It was a reminder that music carries unusual influence.
That influence is the focus of this message in the Bad Habits of Good People series. Dr. Greene's warning is direct: what people allow into their minds will shape their hearts, whether they want it to or not. The Christian life is not fought only in public decisions, outward habits, or visible acts of obedience. It is also fought in the quiet space of attention, imagination, memory, and desire.
Dr. Greene points to Philippians 4:8, where the apostle Paul calls believers to think on whatever is true, noble, just, pure, lovely, of good report, virtuous, and praiseworthy. For Dr. Greene, this verse is not a decorative thought for religious reflection. It is a practical filter for the inner life. The mind is not spiritually passive. What enters it repeatedly begins to shape what a person loves, tolerates, celebrates, excuses, and eventually imitates.
That is why Dr. Greene says music, media, and entertainment are not spiritually neutral. They may seem casual, entertaining, or harmless in the moment, but repeated exposure has a forming effect. Songs are especially powerful because they combine words, emotion, repetition, rhythm, and memory. A person may forget a lecture, a warning, or even a sermon outline, but a lyric can remain lodged in the mind for years.
The Bible recognizes that singing has a formative role. Dr. Greene highlights Ephesians 5:19, which speaks of psalms, hymns, and spiritual songs, with believers singing and making melody in their hearts to the Lord. He also points to Colossians 3:16, where Paul connects singing with the word of Christ dwelling richly among God's people, including teaching and admonishing one another with wisdom. In 1 Corinthians 14:26, Paul says that when believers come together, all things should be done for edification.
Taken together, these passages show that singing is more than musical expression. It can teach. It can admonish. It can build up. It can place truth into memory. It can help shape a congregation's understanding of God, sin, grace, worship, obedience, and hope. Dr. Greene uses these passages to explain why the content of what people sing and hear matters.
This principle applies beyond church music. Dr. Greene warns that much of modern music celebrates rebellion, despair, immorality, anger, and mockery of God. His concern is not simply that certain songs sound worldly or belong to a particular style. His concern is the message being repeated. Even when music is catchy or clever, its content can train the heart in directions that pull people away from reverence, gratitude, and hope.
Dr. Greene describes this process as gradual. It does not happen overnight. It happens song by song and lyric by lyric. Over time, attitudes shift and values erode. This is one of the hidden dangers of entertainment: it often works slowly enough that people do not notice the change while it is happening. What once sounded shocking begins to sound normal. What once stirred discomfort becomes background noise. What once would have been rejected becomes familiar.
Paul's warning, as Dr. Greene presents it, is simple: guard what is allowed to shape the inner life. A person's thoughts are not disconnected from the rest of life. Thoughts shape affections. Affections shape choices. Choices shape habits. Habits shape character. Character shapes a life.
Dr. Greene also connects this concern to America's early spiritual formation. He explains that early Americans understood the role of hymns as tools of discipleship. Hymns were not merely background music or sentimental religious tradition. They taught theology, reinforced virtue, and anchored people in biblical truth. In that sense, singing helped carry doctrine into homes, churches, communities, and generations.
He points to hymns associated with Isaac Watts, including "When I Survey the Wondrous Cross," "Joy to the World," "God, Our Help in Ages Past," and "Alas, and Did My Savior Bleed." He also mentions Charles Wesley, the brother of John Wesley, who wrote thousands of hymns connected to the Methodist revival and the Great Awakening, including "Hark! The Herald Angels Sing," "And Can It Be," and "Christ the Lord Is Risen Today." Dr. Greene also notes that John Newton's "Amazing Grace" continues to captivate Christians today.
The point is not that a song is good merely because it is old. Dr. Greene repeats the better observation: these hymns are not good because they are old; they are old because they are good. They endured because they carried weight. They taught truth. They strengthened worship. They gave believers language for reverence, repentance, gratitude, hope, and praise.
That observation matters in a culture where media consumption is nearly constant. Dr. Greene says people today consume more media than any generation in history. Music plays in cars, stores, headphones, and homes. Entertainment follows people through their phones and screens. The question is not whether people are being influenced. The question is what is influencing them.
This question should not be treated lightly. Influence is rarely limited to obvious instruction. A person does not need to sit under a formal lecture in order to be discipled by a message. Repetition can disciple. Desire can disciple. Humor can disciple. A playlist can disciple. A show can disciple. A constant stream of lyrics, stories, jokes, images, and attitudes can train the heart to see good as boring, evil as exciting, reverence as outdated, and holiness as restrictive.
Dr. Greene warns that if people consistently feed their minds content that glorifies sin, mocks holiness, or trivializes God, they should not be surprised when spiritual sensitivity dulls. This is not presented as a sudden collapse but as a slow dulling. The heart becomes less alert. The conscience becomes quieter. Discernment weakens. What is sacred becomes less weighty. What is destructive becomes less concerning.
The image Dr. Greene uses is practical and easy to understand: just as people would not constantly feed their bodies junk and expect health, they cannot constantly feed their souls spiritual junk and expect clarity. Diet affects the body. Media affects the mind and soul. What enters through the eye and ear shapes the life.
This does not require Christians to live fearfully or suspiciously toward every song, film, show, or form of entertainment. Dr. Greene's message is not a call to panic. It is a call to intentionality. The concern is not merely whether a piece of entertainment is technically permissible. The deeper question is whether it is spiritually forming a person in a direction that strengthens faith or weakens it.
Dr. Greene offers simple diagnostic questions. Does this draw a person closer to God or dull reverence? Does it strengthen virtue or normalize sin? Does it fill the mind with truth or crowd it out? These questions are useful because they move beyond surface-level labels and ask what the content is actually doing.
For families, these questions matter in the home. Parents and grandparents may need to think carefully about what fills the atmosphere of daily life. Children often learn values not only from formal instruction but from what is repeated, laughed at, praised, tolerated, and played in the background. A household's soundtrack can quietly shape what children think is normal, admirable, funny, rebellious, or meaningful.
For churches, the message also carries weight. Worship songs are not filler before preaching. They are teaching tools. They help form what people remember about God. If a congregation sings shallow ideas repeatedly, those ideas can shape shallow worship. If a congregation sings biblical truth with reverence and conviction, those songs can help anchor believers in doctrine and devotion.
For individual Christians, the application begins with honest attention. A person may need to look at playlists, shows, podcasts, social media feeds, and background habits with spiritual seriousness. Not every questionable influence announces itself loudly. Some influences work by repetition and mood. Others work by making sin feel ordinary or holiness feel strange. Others simply crowd out better things until the mind has little space left for what is true, noble, just, pure, lovely, virtuous, and praiseworthy.
A practical step is to begin by listening more carefully. Instead of treating entertainment as neutral noise, believers can ask what a song or show is celebrating. What kind of person does it encourage someone to become? What does it make light of? What does it make attractive? What does it make shameful? What does it teach about God, people, authority, purity, courage, gratitude, despair, anger, or hope?
Another step is replacement, not merely removal. Dr. Greene's message does not simply warn against corrosive content; it points toward what strengthens faith. Believers can feed their minds with music and media that reinforce biblical truth, gratitude, reverence, courage, and hope. This may include hymns, worship music, Scripture-saturated songs, thoughtful teaching, and content that encourages virtue rather than cynicism.
This is especially important because the mind cannot remain empty. If harmful content is removed but nothing good is cultivated, old habits often return. The better pattern is to replace what corrodes with what strengthens. A person can intentionally create a healthier spiritual diet by choosing songs, words, and rhythms that lift the mind toward God.
Dr. Greene's final emphasis is clear: what feeds the mind feeds the soul, and what feeds the soul shapes the life. Strong faith and lasting freedom require intentional formation. People are always being shaped by something. The wise response is to choose, with care and conviction, what is allowed to shape the heart.
The message ends with a fitting call: keep the light of God's praises burning. Praise is not merely a religious activity for Sunday mornings. It is a way of resisting spiritual dullness. It is a way of filling the mind with truth. It is a way of teaching the heart what is worthy. In a culture of constant noise, faithful praise becomes an act of attention, worship, and endurance.
