Day 3: Children of God, Love One Another

Reading: 1 John 3

Listen to: 1 John chapter 3

Historical Context

First John 3 opens with one of the most emotionally charged exclamations in the New Testament: “See what great love the Father has lavished on us, that we should be called children of God! And that is what we are!” (3:1). The Greek word translated “lavished” (dedoken) literally means “given” – God has given us this love as a gift. But the word translated “what great” (potapen) is even more striking. Originally it meant “from what country?” – it was used to describe something so extraordinary that one had to ask where it came from, as though it belonged to another world entirely. John is saying that God’s love is so astonishing, so alien to normal human experience, that we must stand back and marvel at it as at something from another realm.

The identity language that follows is central to John’s pastoral strategy. In a community shaken by the departure of false teachers who claimed superior spiritual status, John grounds the remaining believers’ identity not in their spiritual achievements but in God’s initiative: “we should be called children of God – and that is what we are.” The present tense is emphatic. They are not aspiring to become God’s children; they already are. But there is also a “not yet” dimension: “what we will be has not yet been made known” (3:2). The tension between “already” and “not yet” runs through the entire New Testament, but John resolves it with a breathtaking promise: “when Christ appears, we shall be like him, for we shall see him as he is.” The verb “see” (opsometha) implies direct, unveiled vision – the beatific vision that theologians throughout church history have identified as the ultimate human destiny. Transformation comes not from effort but from sight: seeing Christ as he truly is will complete our transformation into his likeness.

The Cain reference (3:12) introduces a sharp negative example. John asks, “Why did Cain murder his brother?” and answers: “Because his own actions were evil and his brother’s were righteous.” In the Johannine framework, Cain represents the fundamental disposition of hatred that characterizes those who belong to the evil one. The choice of example is deliberate: Cain was the first murderer, and his crime was fratricide – the killing of a brother. The secessionists’ hostility toward the faithful community is thus cast as a repetition of the original pattern of brother-hatred. John then makes the startling equation: “Anyone who hates a brother or sister is a murderer” (3:15). This is not hyperbole but theological logic. In God’s moral universe, hatred and murder share the same root disposition – the refusal to recognize the divine image in the other person and the willingness to destroy them for one’s own benefit.

The positive counterpart is love, and John defines it with reference to its supreme exemplar: “This is how we know what love is: Jesus Christ laid down his life for us” (3:16). The Greek phrase hyper hemon (“for us”) carries substitutionary weight – Christ died in our place, on our behalf. John immediately draws the practical implication: “And we ought to lay down our lives for our brothers and sisters.” This is not a call to martyrdom in the abstract but a principle that governs the most mundane aspects of community life, as John’s next sentence makes clear: “If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person?” (3:17). The move from Calvary to the sharing of material goods is characteristically Johannine – love that is unwilling to sacrifice possessions is unlikely to sacrifice life.

The command to love “not with words or speech but with actions and in truth” (3:18) is one of the most quoted verses in 1 John, and rightly so. The Greek word for “actions” (ergo) is the word for work, labor, concrete deed. The word for “truth” (aletheia) means not sincerity of feeling but correspondence to reality. John is calling for love that is visible, tangible, and costly – love that can be observed and measured by its effects in the real world, not merely professed in spiritual language.

The closing section (3:19-24) addresses the problem of a condemning heart. In a community that has been told their faith is inadequate by departing teachers who claimed superior knowledge, many believers would have struggled with deep insecurity. John provides a remarkable remedy: “If our hearts condemn us, we know that God is greater than our hearts, and he knows everything” (3:20). This is not an invitation to ignore conscience but a reminder that God’s knowledge is more comprehensive and more gracious than our self-assessment. A heart tormented by guilt can find rest not in self-justification but in the God who sees the full picture – including the work of Christ that covers our failures. The assurance comes from keeping his commands (which John reduces to two: believe in Christ and love one another) and from the Spirit he has given us. The objective markers of faith – belief, love, and the Spirit’s presence – provide stability when subjective feelings of guilt threaten to overwhelm.

Key Themes

• The astonishing identity of God’s children – Believers are children of God not by achievement but by divine gift, already possessing this identity in the present while awaiting its full revelation when Christ appears and transforms them into his likeness
• Love defined by the cross – Authentic love is not a feeling or a word but an action modeled on Christ’s self-sacrifice, expressed concretely through the sharing of material possessions with those in need
• Assurance beyond a condemning heart – When guilt and self-doubt assail, believers can rest in a God who is greater than their hearts, whose knowledge encompasses both their failures and Christ’s completed work on their behalf

Connections

• Old Testament Roots: The Cain and Abel narrative (Genesis 4:1-16) provides the negative paradigm for brother-hatred. The call to share material goods echoes Deuteronomy 15:7-8 (“do not be hardhearted or tightfisted toward your poor brother”). The “children of God” language builds on Israel’s identity as God’s firstborn son (Exodus 4:22).
• New Testament Echoes: “Children of God” connects to John 1:12-13 and Romans 8:14-17. The “not with words but with actions” theme parallels James 2:15-17 (“faith without deeds is dead”). The condemning heart section anticipates Romans 8:1 (“no condemnation for those in Christ”).
• Parallel Passages: Romans 8:14-17 (adopted children, heirs), James 2:14-17 (faith and deeds), Matthew 25:31-46 (practical love as evidence of faith), Galatians 5:6 (faith working through love)

Reflection Questions

1. John says that when Christ appears, “we shall be like him, for we shall see him as he is” (3:2). What does it mean that transformation comes through seeing rather than through striving? How does this reshape your understanding of spiritual growth?
2. John moves directly from “Jesus laid down his life for us” to “if anyone has material possessions and sees a brother in need” (3:16-17). Why does he make this immediate connection between the cross and the sharing of resources? What does this say about the nature of love?
3. “If our hearts condemn us, God is greater than our hearts” (3:20). How do you distinguish between legitimate conviction of sin (which leads to repentance) and false condemnation (which leads to despair)? How does this verse help?

Prayer

Father, we stand in awe at the love you have lavished on us – love so extraordinary it must come from another world entirely. Thank you for calling us your children and for the promise that one day we will see Christ as he truly is and be transformed into his likeness. Forgive us when our love remains in words and speech rather than in action and truth. Open our hands and our resources to brothers and sisters in need, that the self-giving love of the cross might become visible in the way we share our lives. And when our hearts condemn us, remind us that you are greater than our hearts. You know everything – including the atoning work of your Son that covers all our failures. Amen.
