Listening to the Voice of Truth | 1 John 4:1-6 | This Week’s Devotions
This week's devotions dig deeper into Sunday's message, "Listening to the Voice of Truth", from 1 John 4:1-6. John tells the church not to believe every spirit but to test them, and he gives a simple way to do it: does the teaching confess that Jesus Christ has come in the flesh? That test carried real weight in the first century, and it still does now, in a world with more voices competing for our attention than John could have imagined.
Over the next five days, you'll trace that test through Scripture. You'll sit with the Bereans, who tested even Paul's preaching against the Word. You'll consider what it means that the one who lives in you is greater than the one who is in the world. And you'll ask what it looks like to have ears tuned enough to recognize your Shepherd's voice.
Day 1: Do Not Believe Every Spirit
Scripture Reading: Deuteronomy 13:1-5 & Acts 17:10-12
Reflection:
Moses warned Israel about a specific and subtle danger: a prophet might arise who performs a sign or wonder, the sign actually comes true, and yet the prophet uses it to lead them after other gods. The miraculous is not self-authenticating. A sign that works is not necessarily a sign that God sent. Israel was to test the prophet not by the impressiveness of his credentials but by the content of his message. If it led away from the Lord, it was to be rejected regardless of how compelling the presentation.
The Bereans in Acts 17 became the model of this kind of discernment. They received Paul's message with eagerness, not suspicion, but examined the Scriptures daily to see if what he said was true. Luke's comment is telling: "Therefore many of them believed." Their willingness to test the message was not an obstacle to faith. It was the pathway through which genuine faith was formed, grounded in something more than a speaker's charisma or a crowd's enthusiasm.
John opens 4:1 with a command as relevant now as it was in the first century: do not believe every spirit, but test the spirits to see whether they are from God. The default posture toward spiritual claims and religious teachers is not credulity but careful, humble, Scripture-anchored evaluation. This is not cynicism; John assumes the genuine exists, or there would be nothing worth testing for. Many false prophets have gone out into the world, and the ease with which compelling personalities can bypass careful thought has not diminished with time.
Questions to consider:
Moses warned that a prophet could perform genuine signs and still be leading people away from God. How does that caution reshape the way you evaluate spiritual teachers and experiences, especially those that seem to carry obvious power or fruit?
The Bereans tested even Paul's teaching against Scripture and were commended for it. What does that tell you about the relationship between eagerness to receive truth and the discipline of testing what you receive?
John says 'do not believe every spirit'; the default is not credulity but careful testing. Where in your own spiritual life are you most tempted to lower your guard and simply accept what sounds good or feels right without examining it?
Day 2: Testing the Spirits
Scripture Reading: 1 Corinthians 12:1-3 & Galatians 1:6-10
Reflection:
Paul tells the Corinthians that no one speaking by the Spirit of God ever says "Jesus is accursed," and no one can say "Jesus is Lord" except by the Holy Spirit. This simple test cuts through enormous complexity. The Spirit of God does not contradict himself. He will not inspire a message that dishonors the Son he was sent to glorify. The confession of Jesus as Lord, the risen, reigning, divine Son of God, is the irreducible minimum that the Spirit always produces and never undermines.
Paul's letter to the Galatians opens with one of the most severe statements in all his letters: if anyone preaches a gospel contrary to the one you received, even Paul himself, even an angel from heaven, let him be accursed. He says it twice. The gospel is not a starting point that can be modified as spiritual understanding develops. It is fixed, received, handed down, and any modification in the direction of adding requirements to grace is not an improvement. It is a different gospel, which is no gospel at all.
These two passages give the believer a practical compass for testing spirits. Ask: does this teaching confess Jesus as Lord, fully divine, fully human, risen and reigning? And does it preserve the gospel of grace, salvation by Christ alone, through faith alone, to the glory of God alone? A teaching that scores well on one but not the other should raise questions. A teaching that fails both is not to be received regardless of how spiritually impressive its source appears.
Questions to consider:
Paul says the irreducible confession is 'Jesus is Lord,' not merely 'Jesus is significant' or 'Jesus is inspiring.' What difference does it make in practice whether someone treats Jesus as Lord versus treating him as a valuable spiritual resource?
Paul was willing to include himself and even angels in the category of those who could not be trusted if they preached a different gospel. How does that level of seriousness about doctrinal faithfulness compare with the way doctrine is typically treated in the churches and Christian communities you have been part of?
The Galatian error was adding requirements to grace, not replacing it entirely but supplementing it. What are the contemporary equivalents of that error that you see most clearly in today's church, and how do you guard against it in your own thinking?
Day 3: Every Spirit That Confesses Jesus
Scripture Reading: John 1:14, Colossians 2:8-10, & 1 Timothy 3:16
Reflection:
John's test in 4:2 is specific: every spirit that confesses that Jesus Christ has come in the flesh is from God. The phrase "come in the flesh" is not accidental. It targets the precise point at which early Gnostic teachers drew their lines, teaching that Jesus only appeared to be human, or that the divine Christ temporarily inhabited a human body and departed before the crucifixion, because the material world was beneath the dignity of true divinity. John's test targets that error at its root.
John's Gospel opens with the most direct possible refutation: "The Word became flesh and dwelt among us." Not appeared to become flesh. Not temporarily inhabited a human vehicle. The Word became flesh, a permanent, irreversible union of the divine Son with human nature. Paul tells the Colossians that in Christ "the whole fullness of deity dwells bodily," not partially, not temporarily, but completely.
Paul's hymn in 1 Timothy 3 celebrates exactly this mystery: "He was manifested in the flesh, vindicated by the Spirit, seen by angels, proclaimed among the nations, believed on in the world, taken up in glory." Every line affirms something that happened in history, in a body, to a real person. The incarnation is the hinge on which the whole gospel turns. A Jesus who was not truly human cannot truly represent us. A Christ who was not truly divine cannot truly save us. The confession that Jesus Christ has come in the flesh is the confession that the one who saves you is exactly who he needed to be.
Questions to consider:
John's test targets the specific error of denying Christ's full humanity. Why do you think the humanity of Jesus is so theologically important? What would be lost if Jesus only appeared to be human rather than truly being so?
Paul says the whole fullness of deity dwells bodily in Christ, not partially, not temporarily. How does the completeness of that union between divine and human affect the way you understand prayer, the sacraments, and Christ's ongoing intercession for you?
The ancient confessions of the church, like the one Paul quotes in 1 Timothy 3, were crafted to preserve precisely these truths. How can you cultivate a living appreciation for creeds and confessions rather than treating them as cold formulas?
Day 4: Greater Is He Who Is In You
Scripture Reading: Romans 8:31-37 & 2 Kings 6:15-17
Reflection:
Elisha's servant woke to find an army surrounding the city, horses and chariots everywhere, no apparent way of escape. His response was entirely reasonable: "Alas, my master! What shall we do?" And Elisha's answer was not a battle plan but a prayer: "O LORD, please open his eyes that he may see." The servant's eyes were opened, and he saw the mountain full of horses and chariots of fire surrounding Elisha. The enemy army had not changed. The reality surrounding them had simply become visible. His panic was the panic of a man who could only see part of the picture.
Paul in Romans 8 works through a similar logic. If God is for us, who can be against us? Not in the sense that nothing can harm us; Paul lists tribulation, distress, persecution, famine, nakedness, danger, and sword as real realities. But none of these things can ultimately separate us from the love of God in Christ Jesus or frustrate his purposes for those he has called. The one who is for us is greater than anything arrayed against us.
John says in 4:4 with quiet confidence: "he who is in you is greater than he who is in the world." The false prophets have the spirit of the world behind them. The believer has the Spirit of the living God within. This is not naive optimism or a denial of real spiritual opposition. It is a call to accurate accounting. The servants of darkness are real, their influence is real, but the one who indwells his people is infinitely greater.
Questions to consider:
Elisha's servant panicked because he could only see part of the picture, the enemy army without the surrounding host of God. Where in your life right now are you most prone to making decisions or losing hope based on an incomplete view of what is actually happening?
Paul's 'who can be against us' is not a denial of real opposition but a declaration about ultimate outcomes. How do you hold together the honesty that real threats exist with the confidence that the one for you is greater than anything against you?
John says 'he who is in you is greater than he who is in the world.' How does that statement function in your daily life? Is it a truth you reach for in moments of spiritual pressure, or does it remain more theoretical than operational?
Day 5: Whoever Knows God Listens to Us
Scripture Reading: John 10:1-16, 27 & 2 Timothy 4:1-5
Reflection:
Jesus describes the relationship between a shepherd and his sheep in terms of mutual recognition. The sheep hear his voice and follow him, not a stranger, because they do not know the voice of strangers. The knowing is reciprocal: the good shepherd knows his sheep, and his sheep know him. This is the relational familiarity of those who have spent time together, who have learned what the voice sounds like, who have followed it through places that proved trustworthy. A stranger can imitate a shepherd's call, but the sheep who truly know their shepherd will notice the difference.
Paul's charge to Timothy carries the weight of a last testament. The time is coming when people will not endure sound teaching but will accumulate teachers to suit their own passions, turning away from truth and wandering into myths. The drift Paul describes is not passive; people will actively seek out teachers who confirm what they already want to believe. The ear becomes trained to recognize its own preferences reflected back at it. Against that drift, Paul's charge is simple: preach the word, be ready in season and out, fulfill your ministry.
1 John 4:6 says that whoever knows God listens to the apostolic word, and whoever does not know God does not listen to it. This is a diagnostic as much as a promise. The way you respond to the faithful proclamation of Scripture, whether you are drawn to it, nourished by it, and shaped by it, or whether you gravitate toward voices that require less of you, reveals something real about the condition of your soul.
Questions to consider:
Jesus says his sheep know his voice and will not follow a stranger. How do you cultivate the kind of familiarity with Scripture and sound teaching that allows you to recognize the difference between the shepherd's voice and a convincing imitation?
Paul says people will seek out teachers who suit their own passions; the ear becomes trained to hear what it wants to hear. Where in your own patterns of reading, listening, and learning are you most vulnerable to that kind of self-confirmation bias?
As you reflect on this whole week, from testing the spirits to the confession of Christ's full humanity, to the greater one within you and the recognizing of the shepherd's voice, what is the most important adjustment you need to make in how you listen and what you listen to?
