1 João 3

BLIVRE · Chapter 3/5

1Vede quão grande amor o Pai tem nos dado, que fôssemos chamados filhos de Deus. Por isso o mundo não nos conhece, pois não conhece a ele.

2Amados, agora somos filhos de Deus, e ainda não está manifesto o que seremos. Porém sabemos que, quando ele se manifestar, seremos semelhantes a ele, pois o veremos como ele é.

3E todo aquele que tem nele essa esperança purifica a si mesmo, como também ele é puro.

4Todo aquele que pratica o pecado também pratica injustiça, pois o pecado é injustiça.

5E sabeis que ele apareceu para tirar os nossos pecados; e nele não há pecado.

6Todo aquele que nele permanece não pratica o pecado; todo aquele que costuma pecar não o viu nem o conheceu.

7Filhinhos, ninguém vos engane. Quem pratica a justiça é justo, assim como ele é justo.

8Quem pratica o pecado é do diabo, pois o diabo peca desde o princípio. Para isto o Filho de Deus se manifestou, para desfazer as obras do diabo.

9Todo aquele que é nascido de Deus não pratica o pecado, pois a sua semente reside nele; e não pode praticar o pecado, porque é nascido de Deus.

10Nisto são reconhecíveis os filhos de Deus, e os filhos do diabo: todo aquele que não pratica a justiça, e não ama o seu irmão, não é de Deus.

11Pois esta é a mensagem que ouvistes desde o princípio: que nos amemos uns aos outros.

12Não [sejamos] como Caim, [ que] era do maligno, e matou o seu irmão. E por que o matou? Porque as suas obras eram más, e as do seu irmão justas.

13Meus irmãos, não vos surpreendeis se o mundo vos odeia.

14Nós sabemos que já passamos da morte para a vida, pois amamos os irmãos. Quem não ama[seu] irmão permanece na morte.

15Todo aquele que odeia o seu irmão é homicida. E sabeis que nenhum homicida tem a vida eterna habitando nele.

16Nisto conhecemos o amor: ele deu a sua vida por nós. E nós devemos dar as [nossas] vidas pelos irmãos.

17Se alguém tiver bens do mundo, e vir o seu irmão em necessidade, e não se compadecer dele, como pode o amor de Deus estar nele?

18Meus filhinhos, amemos não de palavra, nem de língua, mas sim com ação e verdade.

19E nisto sabemos que somos da verdade, e teremos segurança nos nossos corações diante dele.

20Pois, se o nosso coração [nos] condena, maior é Deus que o nosso coração, e conhece tudo.

21Amados, se nosso coração não nos condena, temos confiança diante de Deus.

22E qualquer coisa que pedirmos, dele receberemos; porque guardamos os seus mandamentos, e fazemos o que lhe agrada.

23E este é o seu mandamento: que creiamos no nome do seu Filho Jesus Cristo, e nos amemos uns aos outros, como ele nos mandou.

24E a pessoa que guarda os seus mandamentos está nele, e ele nela. E nisto sabemos que ele está em nós: pelo Espírito que ele nos deu.

Summary

John celebrates the great love of God that makes us his children, and teaches that whoever habitually practices sin does not truly know God. He contrasts the example of Cain, who hated and killed his brother, with the call to love one another in deed and truth, not merely in word.

Explanation

The identity of being 'children of God' is presented as already real in the present, even though its future fullness is not yet fully visible—creating a tension between the 'already' and the 'not yet' common in New Testament theology. The use of Cain as a negative example, referring to the first murder in biblical history (Genesis 4), illustrates the extreme opposite of the brotherly love John demands from his readers. The famous instruction to love 'not in word, neither in tongue, but in deed and in truth' (3:18) sums up the practical tone of the whole letter: feelings of love without concrete action are not enough. Today's practical application is to check whether the love we profess translates into real, tangible help for those in need.

Fun facts

  • The reference to Cain (3:12) is the only direct mention of that Genesis 4 story in all the New Testament letters outside the book of Hebrews, showing how this narrative became a recurring symbol of fratricidal hatred in the Christian tradition.

Verse-by-verse explanation

  1. 1 João 3:1Opens the chapter in astonishment at the love of God: being called “the sons of God” is such a great privilege that the world itself, not knowing God, also fails to recognize that identity in Christians.
  2. 1 João 3:2Saying “when he shall appear, we shall be like him” speaks of a future transformation tied to Christ’s return, without spelling out exactly what that likeness would be — the text’s focus is on the hope generated by this promise, not on a detailed physical or spiritual description.
  3. 1 João 3:3Links the hope of being like Christ, mentioned in the previous verse, to a practical consequence: whoever has this hope strives to live purely, just as He is pure.
  4. 1 João 3:4Defines sin directly: it is the same as transgression of the law — that is, living against God’s law and will — a simple definition that underlies the whole argument that follows.
  5. 1 João 3:5Recalls the purpose of Jesus’ coming: to take away people’s sins — and reinforces that in Him there was no sin at all, the basis for the standard of purity expected of Christians.
  6. 1 João 3:6Contrasts remaining in Christ with living in sin: whoever truly remains in Him does not live in a pattern of sin; whoever does live that way shows that he never truly came to know Him.
  7. 1 João 3:7Warns against any deception: practicing righteousness is the real sign of being righteous, following the standard set by Christ Himself — it isn’t enough to claim it, it has to show up in practice.
  8. 1 João 3:8Contrasts whoever lives in sin with the devil, who sins from the beginning, saying that the very purpose of Jesus’ coming was precisely to destroy the works of the devil.
  9. 1 João 3:9The statement that whoever is “born of God” cannot sin is one of the most debated points in the letter, because it seems to contradict chapter 1, which already said that everyone sins. A common reading is that the text refers to a lifestyle pattern of sin, not isolated failures — but different Christian traditions interpret this tension in different ways.
  10. 1 João 3:10Sums up the test for telling apart “the children of God” from “the children of the devil”: it isn’t a visible mark, it’s practice — whoever does not act righteously and does not love his brother is not of God.
  11. 1 João 3:11Presents the letter’s central commandment, which readers already knew from the beginning: to love one another — a theme that dominates the rest of the chapter.
  12. 1 João 3:12Cain, the son of Adam and Eve who killed his brother Abel in Genesis 4, is cited here as an example of the hatred that arises when a person’s own works are evil and another’s are righteous — a moral contrast, not merely a historical account.
  13. 1 João 3:13Prepares readers for the world’s hostility: it should not be surprising to be hated by those who live outside the values described in the letter.
  14. 1 João 3:14Gives a concrete spiritual test: loving the brethren is a sign of having already passed from death to life; whoever does not love, the text says, “abideth in death.”
  15. 1 João 3:15Goes further, comparing hatred to murder itself: whoever hates his brother is called a murderer, and the text reminds that no murderer has eternal life abiding in him.
  16. 1 João 3:16Linking “love” to the willingness to lay down one’s life for the brethren uses Christ’s example as the ultimate standard, but applies that standard to concrete everyday gestures, as the text itself details in the next verse about helping someone in need.
  17. 1 João 3:17Makes love practical and concrete: seeing a brother in material need and shutting up one’s heart against him is incompatible with claiming to have the love of God.
  18. 1 João 3:18The instruction to love “not in word, neither in tongue; but in deed and in truth” sums up the letter’s argument that genuine love is proven in actions, not just in declarations.
  19. 1 João 3:19Links living according to the truth, the practical love described earlier, to inner security: this consistency is what allows the heart to be at rest before God.
  20. 1 João 3:20Acknowledges that sometimes one’s own heart accuses a person of things done — but reminds that God is greater than those inner accusations and knows everything more precisely than human conscience does.
  21. 1 João 3:21On the opposite side: when the heart does not condemn, it produces genuine confidence to approach God, without fear.
  22. 1 João 3:22Links this confidence to answered prayer: whoever keeps God’s commandments and does what is pleasing to Him receives what he asks — a promise conditioned on obedience.
  23. 1 João 3:23Sums up God’s commandment in two parts that in practice are really one: to believe in the name of Jesus Christ and to love one another, just as He commanded.
  24. 1 João 3:24Closes the chapter explaining how to know whether this obedience is really happening: through the presence of the Holy Spirit that God gave — it is this presence that confirms the mutual abiding between God and the believer.
