Children of God
Key text — 1 John 3:1–3 (ESV)
See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him.
Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is.
And everyone who thus hopes in him purifies himself as he is pure.
The Ache to Belong
When I first read the opening chapters of Harry Potter, I felt that ache for the boy under the stairs. Harry is forgotten, unwanted, convinced the cupboard is all there is—until a letter arrives and tells him he belongs. He has a name, a place, a story.
That longing to be known and claimed sits in every human heart. And that’s exactly the note John strikes:
“See what kind of love the Father has given to us, that we should be called children of God—and so we are.”
The phrase “what kind of love” (Greek potapēn) is a gasp: what foreign, otherworldly love is this? God didn’t only forgive; He adopted. He didn’t just clean the slate; He brought us home and wrote a new name over our lives.
This short passage unfolds that reality in three movements:
- We are already loved.
- We are not yet complete.
- We are being made pure.
1) We Are Already Loved (v. 1 — Past Foundation)
John begins with wonder, not command: “See…” The verb “has given” sits in the perfect tense—love bestowed in the past that continues in the present. God’s love didn’t flicker and fade; it landed and abides.
Then the tender assurance: “and so we are.” Not just called children—we are children. Adoption in Scripture isn’t sentiment; it’s a covenant reality sealed by the Spirit. As the Reformed tradition puts it, union with Christ brings not only pardon but sonship. “The Son of God became the Son of Man, that the sons of men might become sons of God.”(attributed to early Christian reflection; beloved by Calvin)
John also adds a sober line: “The world does not know us because it did not know Him.” Family resemblance brings cultural friction. If the world misunderstood the Father, it will often misread His children.
Two images to hold:
- Courtroom: The judge’s gavel declares the adoption—your status changes.
- Living room: The Father’s voice at breakfast—your heart changes.
The gospel gives both: justification in the courtroom, adoption in the living room. Live from that love.
Takeaways
- Recover your wonder. Don’t just parse this love—behold it.
- Rest in belonging. “And so we are” means security now, not probation.
- Expect misunderstanding. Family likeness won’t always win applause.
2) We Are Not Yet Complete (v. 2 — Future Hope)
“We are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is.”
Identity now; destiny not yet revealed. The Christian life stretches between assurance and anticipation.
The heart of our hope is the appearing of Christ. Notice the order: seeing leads to becoming. Historic theology calls this the Beatific Vision—the unveiled sight of the risen Lord that transforms us fully into His likeness. Glorification isn’t a self-upgrade; it’s the completion of adoption. What is partial becomes whole; what is dim becomes face to face (1 Cor. 13:12).
- Live in confident hope. John doesn’t say “might”—he says “we shall be like Him.”
- Let mystery humble you. “Has not yet appeared” invites worship, not worry.
- Fix your gaze forward. Our hope is not a trend; it’s a Person who is coming.
3) We Are Being Made Pure (v. 3 — Present Pursuit)
“And everyone who thus hopes in him purifies himself as he is pure.”
Hope fuels holiness. John’s grammar matters: he doesn’t say “purify yourself to earn hope,” but “everyone who has this hope purifies himself.” The verb (hagnizei) is present, ongoing—a rhythm, not a one-off.
Think window-washing: the sun outside is blazing, but grime on the glass dims the room. Sanctification is the Spirit cleaning the panes of our hearts so Christ’s light shines through. You don’t create the light; you keep the glass clear—repentance, faith, obedience, again and again.
Reformed reflection: The Spirit who secured our adoption (v. 1) and guarantees our glorification (v. 2) is the same Spirit who sanctifies us now. Christ justifies no one He does not also sanctify. Holiness isn’t an elective for advanced Christians; it’s the normal fruit of union with Christ.
- Let hope shape choices. A vivid horizon makes compromise feel cheap.
- Practice repentance as a habit. Cleansing is daily, not just crisis-driven.
- Pursue purity together. John’s “everyone” assumes community.
The Whole Arc in Three Verses
- Love given (past): “See what kind of love…”
- Hope guaranteed (future): “We shall be like him…”
- Purity pursued (present): “Everyone who thus hopes… purifies himself.”
The Father’s love reached back before time.
The Son’s appearing stretches beyond time.
The Spirit’s work meets you in real time—today.
Your life right now is the meeting place of eternity and grace.
