Abide in Him | 1 John 2:18-27 | This Week’s Devotions
This week's devotional turns to a passage that names something believers have always had to reckon with: opposition to the truth does not only come from outside the church, it can rise up from within it. John's readers had already watched people walk away from the faith, and he doesn't soften what that departure revealed. But he doesn't leave them there either. He reminds them of what they already possess, the anointing of the Spirit and the truth they were taught from the beginning, and calls them to a single, steady response: abide.
Over the next five days, you'll dig into the doctrine of the incarnation, the sobering reality of departure from the faith, the Spirit's role in discernment, and what it means to stay rooted in Christ when plausible-sounding voices compete for your trust.
If you missed Sunday's sermon on this passage, "Abide in Him," you can watch it here before working through this week's devotional.
Day 1: The Spirit that Denies the Son
Scripture Reading: 1 John 4:1-3 & 2 John 7
Reflection:
John does not leave his readers guessing about what the antichrist spirit looks like. He identifies it precisely: it is the spirit that does not confess that Jesus Christ has come in the flesh. The fault line is not political or cultural. It is doctrinal, and it runs directly through the person of Jesus. What you believe about the incarnation is not a secondary matter. It is the load-bearing wall. Get it wrong, and everything else collapses with it.
The teachers John is concerned about were not crude atheists or obvious opponents of the faith. They were inside the community, speaking the language of spiritual knowledge and Christian experience. Their error was a kind of elevation — the material world was too low a thing for the divine to truly inhabit. So they taught that Jesus only appeared to be human, or that the divine presence rested on him temporarily without truly becoming flesh. It sounded sophisticated. It sounded spiritual. And John calls it the spirit of antichrist — not because of its tone but because of what it does to Jesus.
In his second letter John returns to the same point: many deceivers have gone out into the world, those who do not confess the coming of Jesus Christ in the flesh. A Jesus who did not truly take on human flesh cannot truly stand in our place, truly suffer for our sins, or truly intercede for us now as our great high priest. The confession that Jesus Christ has come in the flesh is not one doctrine among many. It is the confession on which your salvation depends.
Questions to Consider:
John identifies the antichrist spirit not by its hostility but by its doctrine — specifically what it says about the incarnation. Why do you think a subtle distortion of who Jesus is can be more dangerous than outright rejection of him?
The false teachers in John's day sounded spiritual and sophisticated. What are the contemporary versions of teaching that sounds elevated or enlightened but quietly diminishes the full humanity or full divinity of Christ?
John says the confession that Jesus Christ has come in the flesh is the test of whether a spirit is from God. How firmly grounded are you in the doctrine of the incarnation — not just as a creed to recite but as a truth you understand well enough to recognize when it is being denied?
Day 2: They Went Out from Us
Scripture Reading: Acts 20:28-32 & 2 Peter 2:1-3, 17-22
Reflection:
Paul's farewell to the Ephesian elders carries the weight of a man who knows he will not see them again in this life. He charges them to pay careful attention to themselves and to all the flock, and then he tells them why: after his departure, fierce wolves will come in among them, not sparing the flock. Worse still, from among their own number men will arise speaking twisted things, to draw away disciples after themselves. The threat is not only external. It comes from within.
Peter is equally unflinching. False prophets arose among the people of Israel, he writes, and false teachers will arise among you. They will secretly bring in destructive heresies, even denying the Master who bought them. And many will follow their sensuality. The path Peter describes is not a sudden cliff edge. It is a slow drift, a gradual exchange of the truth for something that fits the appetites better. By the end of his description, the false teachers are like dogs returning to their own vomit, a viscerally unpleasant image meant to capture the repugnance of turning back from the gospel to the world.
John says of the antichrists who have left: "they went out from us, but they were not of us; for if they had been of us, they would have continued with us." This is a hard and clarifying statement. Departure from the truth reveals something that was always true. Perseverance is not the cause of salvation, but it is one of its marks. Those who are truly the Lord's will, by his grace, continue. That perseverance is itself a gift, not a boast, but a testimony to the faithfulness of the God who keeps what is his own.
Questions to Consider:
Paul warned the Ephesian elders that false teachers would arise from within their own number. How does that internal threat shape the way you think about accountability, discernment, and the importance of sound doctrine within the church you belong to?
Peter describes apostasy not as a sudden fall but as a gradual drift toward what fits the appetites better. What are the early warning signs that someone, including yourself, is beginning to drift from the truth rather than abiding in it?
John says those who departed were never truly 'of us.' That is a sobering statement about the difference between outward association and genuine belonging. How do you hold that truth in a way that produces honest self-examination without producing unhealthy anxiety about your own standing?
Day 3: The Anointing You Have Received
Scripture Reading: Joel 2:28-29 & John 16:12-15
Reflection:
Joel's prophecy was ancient when Peter quoted it on Pentecost: God would pour out his Spirit on all flesh. The democratization of the Spirit's presence was the great promise of the new covenant age. Under the old covenant, the Spirit rested on specific leaders, prophets, and kings for specific purposes. But God promised a day when every member of his people would be filled, taught, and led by the Spirit of God.
Jesus prepares his disciples for exactly this in John 16. He tells them it is to their advantage that he goes away, because if he does not go, the Helper will not come. The Spirit of truth will guide them into all truth, not by bypassing their minds or delivering new revelation beyond Scripture, but by taking what belongs to Christ and declaring it to them, illuminating what has already been given. The Spirit's ministry is inherently Christ-centered. He does not draw attention to himself. He points to the Son, who points to the Father.
This is the "anointing" John speaks of in 2:20 and 2:27, not a private mystical experience available to a spiritual elite, but the indwelling of the Holy Spirit that every genuine believer has received. John's point is remarkable: you do not need a human teacher to tell you whether something is true or false, because the Spirit who dwells in you bears witness to the truth. This does not make teachers unnecessary; it makes discernment possible. The believer who abides in the word and walks in the Spirit has an internal compass that the most sophisticated false teaching cannot permanently corrupt.
Questions to Consider:
Joel's prophecy promised the Spirit for 'all flesh,' not just a spiritual elite. How does the reality that every believer has the Holy Spirit change the way you think about your own capacity for spiritual discernment and understanding of Scripture?
Jesus says the Spirit takes what belongs to Christ and declares it, the Spirit's ministry is Christ-centered, not self-referential. How do you evaluate claims of spiritual experience or spiritual insight in the light of that Christ-centering principle?
John says the anointing 'teaches you about everything.' That is a bold claim in a world full of competing voices. What practices in your life help you cultivate attentiveness to the Spirit's teaching rather than simply absorbing the loudest voices around you?
Day 4: Who Is the Liar?
Scripture Reading: John 8:42-47 & 1 Timothy 4:1-5
Reflection:
Jesus does not mince words in John 8. He tells his opponents that their father is the devil, the father of lies, the one in whom there is no truth. When the devil lies, he speaks out of his own character, because lying is native to who he is. The implication is that deception about Jesus is not merely an intellectual error. It has a spiritual genealogy. It comes from somewhere, and that somewhere is not neutral.
Paul tells Timothy that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons. He does not call these teachers confused or misguided. He calls their teachings demonic. The deceptions he identifies seem almost mundane, forbidding marriage, requiring abstinence from foods, but his point is about the pattern. Teachings that distort the goodness of creation, deny the full humanity of Christ, or add to what God has declared sufficient all draw from the same corrupted source.
John's identification of the liar in 1 John 2:22 is precise: the one who denies that Jesus is the Christ. This is not peripheral theology. It is the load-bearing wall. To deny that Jesus is the Christ is to deny the Father as well, because the Father sent the Son and is known through the Son. Every teaching that finds Jesus admirable but not Lord is operating with a different gospel, one that cannot save because it has replaced the Christ who saves with one who cannot. The truth about Jesus is not one doctrine among many. It is the doctrine on which everything else stands or falls.
Questions to Consider:
Jesus traces the denial of his identity to a spiritual father, the father of lies. How does understanding false teaching as having a spiritual genealogy, not just an intellectual origin, change the seriousness with which you approach doctrinal discernment?
Paul says some will depart from the faith by following 'teachings of demons,' and the examples he gives seem fairly ordinary. What ordinary-sounding teachings in today's church culture do you think most need to be examined carefully against Scripture?
John says denying that Jesus is the Christ also means denying the Father. What is at stake practically, in your prayer life, your ethics, your hope, if the Jesus you believe in is anything less than the Christ John is describing?
Day 5: Abide in What You Have Heard
Scripture Reading: John 15:1-11 & Colossians 2:6-10
Reflection:
Jesus uses a metaphor so organic and concrete that it is almost impossible to spiritualize away: the vine and the branches. The branch does not produce fruit by trying harder. It abides, stays connected, remains attached. And the life that flows through the vine produces fruit as a natural consequence of that connection. Cut the branch off, and it withers. Not because the branch was punished, but because it is no longer drawing life from the source.
Paul urges the Colossians to walk in Christ as they received him: rooted, built up, established in the faith, overflowing with thanksgiving. And then he issues the warning: see to it that no one takes you captive through philosophy and empty deceit, according to human tradition rather than according to Christ. The captivity he warns against is not violent; it is intellectual and spiritual. It happens when the plausible-sounding wisdom of the world is allowed to displace the sufficient wisdom of Christ.
This is John's closing word: let what you heard from the beginning abide in you. Abiding is not passive. It is the active, daily, deliberate choice to remain anchored in the apostolic word, reading it, meditating on it, gathering with others who are shaped by it, measuring every new voice against it. The antidote to the spirit of antichrist is not a more sophisticated apologetic. It is deep rootedness in what has always been true. Those who abide in Christ and in his word will not be swept away by the next plausible deception, because they are drawing life from a source that does not change.
Questions to Consider:
Jesus says the branch abides in the vine; it does not generate life but receives it. Where in your spiritual life are you most tempted to try to generate fruit through your own effort rather than drawing it from your connection to Christ?
Paul warns against being taken 'captive' through plausible-sounding wisdom that displaces Christ. What voices, ideas, or frameworks in your current world are most actively competing with Christ for the role of ultimate wisdom and authority in your thinking?
John's final word is to let what you heard from the beginning abide in you. As you look back over the whole week, from the warnings about false teaching to the anointing of the Spirit to the call to abide, what does faithful abiding look like for you specifically, in this season of your life?
