Align 1 John 3:15 with Jesus' love?
How can we reconcile 1 John 3:15 with Jesus' teachings on love?

The weight of John’s warning

1 John 3:15: “Everyone who hates his brother is a murderer, and you know that eternal life does not reside in a murderer.”

• John echoes the Sixth Commandment but presses it deeper—beyond the external act to the internal motive.

• Hatred is treated not as a lesser sin but as spiritual homicide, because it springs from the same heart–condition that produces literal murder (cf. Mark 7:21).


Jesus already laid the groundwork

Matthew 5:21-22: “You have heard that it was said to the ancients, ‘Do not murder,’ … But I tell you that anyone who is angry with his brother will be subject to judgment.”

• The Sermon on the Mount moves the commandment from the hand to the heart.

• Jesus’ pattern: expose hidden sin, then call for radical love (Matthew 5:43-45; Luke 6:27-28).

• John, years later, applies the same principle in family language—“brother”—underscoring the closeness expected within the body of Christ.


Why hatred equals murder in God’s court

• Same root: both cancel the worth of another image-bearer.

• Same direction: hostility that, unchecked, could culminate in violence (James 1:14-15).

• Same verdict: separation from God’s life, because God Himself is love (1 John 4:8).


The positive alternative—active love

1 John 3:16-18 shows the flip side: “By this we know what love is: Jesus laid down His life for us. And we ought to lay down our lives for our brothers.”

Practical outworking:

– Sacrificial generosity (v. 17).

– Tangible deeds, not mere words (v. 18).

– Refusal to retaliate (1 Peter 3:9).

– Proactive blessing of enemies (Romans 12:14-21).


Walking the love-path daily

• Examine motives—invite the Spirit to expose concealed resentment (Psalm 139:23-24).

• Seek reconciliation quickly (Matthew 5:23-24).

• Guard speech—words can assassinate character (Ephesians 4:29, 31).

• Pray for those who vex you; prayer softens hatred (Matthew 5:44).

• Keep Christ’s cross central—remember you were once God’s enemy yet were loved (Romans 5:8-10).


Assurance for the obedient heart

1 John 3:19: “By this we will know that we belong to the truth, and we will assure our hearts before Him.”

• Love is evidence of spiritual life (1 John 3:14).

• Persistent hatred signals the absence of regeneration (v. 15).

• Ongoing repentance and Spirit-empowered love confirm that eternal life indeed “resides” within.
