Based on 1 John 4:1-6
In a world overflowing with voices—podcasts, social media feeds, bestselling books, charismatic teachers, and endless opinions—how do we know whom to trust? The apostle John wrote to early believers facing a similar challenge: competing claims about Jesus and spiritual truth. His words in 1 John 4:1-6 remain strikingly relevant.
Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world. You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world. They are from the world and therefore speak from the viewpoint of the world, and the world listens to them. We are from God, and whoever knows God listens to us; but whoever is not from God does not listen to us. This is how we recognize the Spirit of truth and the spirit of falsehood. (NIV)
Don’t Believe Everything
John begins with a clear warning: “Do not believe every spirit.” Spiritual claims and religious-sounding messages are not automatically trustworthy. In his day, false teachers denied core truths about Jesus—particularly that the eternal Son of God had truly come in the flesh. Some versions of early heresy treated the physical incarnation as optional or impossible. John calls such denial the spirit of the antichrist, already active.
The same principle applies today. Not every message that uses Christian language, quotes Scripture, or feels inspiring comes from God. Some teachings subtly shift the focus away from the real, historical, crucified and risen Jesus. Others prioritize human wisdom, cultural approval, or personal empowerment over the gospel. Testing the spirits is not cynicism; it is faithful obedience.
The Test: What Do They Say About Jesus?
John gives a concrete criterion: Does this spirit (or teaching, or teacher) acknowledge that Jesus Christ has come in the flesh? The confession is more than intellectual agreement. It means affirming the full reality of the incarnation—that the eternal Son truly became human, lived among us, died for our sins, and rose again. Any message that diminishes Jesus’ deity, humanity, exclusive role as Savior, or the necessity of the cross fails the test.
This test protects the heart of the faith. Christianity stands or falls on who Jesus is. When teachings redefine Him to fit modern preferences—making Him merely a moral example, a political ally, or one path among many—they reveal their source.
Greater Is He Who Is in You
John does not leave believers anxious. He immediately reassures: “You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.” The Holy Spirit who dwells in believers is infinitely greater than any deceptive influence. Victory is not achieved by our cleverness or strength but by the presence of God Himself.
This truth brings courage. We do not navigate spiritual confusion alone. The same Spirit who inspired Scripture also illuminates it and guards God’s people.
Two Audiences, Two Sources
John draws a sharp contrast. Those influenced by the spirit of the world “speak from the viewpoint of the world, and the world listens to them.” Their message often resonates with cultural values—self-fulfillment, relativism, or whatever currently wins applause. In contrast, those who know God listen to the apostolic witness (the “us” of verse 6). Alignment with the testimony of Scripture and the historic faith becomes a mark of the Spirit of truth.
Discernment, then, involves more than checking individual statements. It includes noticing the fruit, the underlying worldview, and whether a teaching draws people toward or away from the Jesus of the Bible.
Living This Out Today
How do we practice this in daily life?
- Measure everything by Scripture’s portrait of Jesus. Does this book, sermon, or online post exalt the incarnate, crucified, and risen Christ—or something else?
- Stay rooted in the community of faith and the Word. Isolation makes us more vulnerable to persuasive but flawed voices.
- Pray for wisdom. The Spirit who is greater than the one in the world delights to give discernment to those who ask.
- Hold truth with humility and love. Testing spirits is not a license for harsh judgment of people; it is protection of the gospel so that we can love others with clarity.
John’s words are both a warning and a comfort. Falsehood is real and active, yet God’s people are not left defenseless. The One who lives in us is greater. As we test the spirits by the standard of Jesus Christ come in the flesh, we walk in the Spirit of truth—and that is freedom.
May we be a people who listen carefully, test wisely, and rest securely in the greater One who dwells within.
