1 João 3

ARC · Chapter 3/5

1Vêde quão grande caridade nos tem dado o Pae, que fossemos chamados filhos de Deus. Por isso o mundo nos não conhece; porque o não conhece a elle.

2Amados, agora somos filhos de Deus, e ainda não é manifestado o que havemos de ser. Porém sabemos que, quando se manifestar, seremos similhantes a elle; porque assim como é o veremos.

3E qualquer que n'elle tem esta esperança, purifica-se a si mesmo, como tambem elle é puro.

4Qualquer que commette peccado, tambem commette iniquidade; porque o peccado é iniquidade.

5E bem sabeis que elle se manifestou, para tirar os nossos peccados; e n'elle não ha peccado.

6Qualquer que permanece n'elle não pecca: qualquer que pecca não o viu nem o conheceu.

7Filhinhos, ninguem vos engane. Quem obra justiça é justo, assim como elle é justo.

8Quem commette o peccado é do diabo; porque o diabo pecca desde o principio. Para isto o Filho de Deus se manifestou, para desfazer as obras do diabo.

9Qualquer que é nascido de Deus não commette peccado; porque a sua semente permanece n'elle; e não-pode peccar, porque é nascido de Deus.

10N'isto são manifestos os filhos de Deus, e os filhos do diabo. Qualquer que não obra justiça, e não ama a seu irmão, não é de Deus.

11Porque esta é a annunciação que ouvistes desde o principio: que nos amemos uns aos outros.

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

13Meus irmãos, não vos maravilheis, se o mundo vos aborrece.

14Nós sabemos que já passámos da morte para a vida, porque amamos os irmãos. Quem não ama a seu irmão permanece na morte

15Qualquer que aborrece a seu irmão é homicida. E vós sabeis que nenhum homicida tem a vida eterna permanecendo n'elle.

16Conhecemos a caridade n'isto, que elle deu a sua vida por nós, e nós devemos dar a vida pelos irmãos.

17Quem pois tiver bens do mundo, e vir o seu irmão necessitado e lhe cerrar as suas entranhas, como estará n'elle a caridade de Deus?

18Meus filhinhos, não amemos de palavra, nem de lingua, senão de obra e de verdade.

19E n'isto conhecemos que somos da verdade, e diante d'elle asseguraremos nossos corações;

20Que, se o nosso coração nos condemna, maior é Deus do que os nossos corações, e conhece todas as coisas.

21Amados, se o nosso coração nos não condemna, temos confiança para com Deus;

22E qualquer coisa que lhe pedirmos, d'elle a receberemos; porque guardamos os seus mandamentos, e fazemos as coisas agradaveis perante elle.

23E o seu mandamento é este: que creiamos no nome de seu Filho Jesus Christo, e nos amemos uns aos outros, como nos deu mandamento.

24E aquelle que guarda os seus mandamentos n'elle está, e elle n'elle. E n'isto conhecemos que elle está em nós, pelo Espirito que nos tem dado.

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.
