1 Yohanes 2:16

2:16 because all that is in the world (the desire of the flesh and the desire of the eyes and the arrogance produced by material possessions) ¹  is not from the Father, but is from the world.

1 Yohanes 3:12

3:12 not like Cain ²  who was of the evil one and brutally ³  murdered his brother. And why did he murder him? Because his deeds were evil, but his brother’s were righteous.

1 Yohanes 4:17

4:17 By this ⁴  love is perfected with ⁵  us, so that we may have confidence in the day of judgment, because just as Jesus ⁶  is, so also are we in this world.

[2:16]  ¹ tn The genitive βίου (biou) is difficult to translate: (1) Many understand it as objective, so that βίος (bios, “material life”) becomes the object of one’s ἀλαζονεία (alazoneia; “pride” or “boastfulness”). Various interpretations along these lines refer to boasting about one’s wealth, showing off one’s possessions, boasting of one’s social status or lifestyle. (2) It is also possible to understand the genitive as subjective, however, in which case the βίος itself produces the ἀλαζονεία. In this case, the material security of one’s life and possessions produces a boastful overconfidence. This understanding better fits the context here: The focus is on people who operate purely on a human level and have no spiritual dimension to their existence. This is the person who loves the world, whose affections are all centered on the world, who has no love for God or spiritual things (“the love of the Father is not in him,” 2:15).

[2:16]  sn The arrogance produced by material possessions. The person who thinks he has enough wealth and property to protect himself and insure his security has no need for God (or anything outside himself).

[3:12]  ² sn Since the author states that Cain…was of the evil one (ἐκ τοῦ πονηροῦ, ek tou ponhrou), in the immediate context this imagery serves as an illustration of 3:8a: The person who practices sin is of the devil (ἐκ τοῦ διαβόλου, ek tou diabolou). This is similar to John 8:44, where Jesus told his opponents “you people are from your father the devil…[who] was a murderer from the beginning.” In both Jewish and early Christian writings Cain is a model for those who deliberately disbelieve; Testament of Benjamin 7:5 looks forward to the punishment of those who “are like Cain in the envy and hatred of brothers.” It is not difficult to see why the author of 1 John used Cain here as a model for the opponents in light of their failure to “love the brothers” (see 1 John 3:17).

[3:12]  ³ tn For the Greek verb σφάζω (sfazw) L&N 20.72 states, “to slaughter, either animals or persons; in contexts referring to persons, the implication is of violence and mercilessness – ‘to slaughter, to kill.’” As a reflection of this nuance, the translation “brutally murdered” has been used.

[4:17]  ⁴ tn The referent of ἐν τούτῳ (en toutw) here is more difficult to determine than most, because while there are both ἵνα (Jina) and ὅτι (Joti) clauses following, it is not clear whether or not they are related to the ἐν τούτῳ. There are actually three possibilities for the referent of ἐν τούτῳ in 4:17: (1) it may refer to the ἵνα clause which immediately follows, so that the love of believers is brought to perfection in that they have confidence in the day of judgment. The main problem with this interpretation is that since the day of judgment is still future, it necessitates understanding the second use of the preposition “in” (second ἐν [en]) to mean “about” or “concerning” with reference to the day of judgment in order to make logical sense. (2) The ἐν τούτῳ may refer to the ὅτι clause in 4:17b, meaning “love is perfected with us…in that just as he [Christ] is, so also are we in this world.” This makes logical sense, and there are numerous cases where ἐν τούτῳ is explained by a ὅτι clause that follows. However, according to this understanding the intervening ἵνα clause is awkward, and there is no other instance of the phrase ἐν τούτῳ explained by a following ὅτι clause where a ἵνα clause intervenes between the two in this way. (3) Thus, the third possibility is that ἐν τούτῳ refers to what precedes in 4:16b, and this also would make logical sense: “By this – by our residing in love so that we reside in God and he resides in us – is love brought to perfection with us.” This has the additional advantage of agreeing precisely with what the author has already said in 4:12: “If we love one another, God remains in us and his love is brought to perfection in us.” Thus option (3) is best, with the phrase ἐν τούτῳ referring to what precedes in 4:16b, and the ἵνα clause which follows indicates the result of this perfection of love in believers: In the future day of judgment they will have confidence. The ὅτι clause would then give the reason for such confidence in the day of judgment: because just as Jesus is, so also are believers in this world – they are already currently in relationship with God just as Jesus is.

[4:17]  ⁵ tn The preposition μετά (meta) means “with” and modifies the verb τετελείωται (teteleiwtai). If the prepositional phrase modified the noun ἡ ἀγάπη which immediately precedes it, it would almost certainly have the Greek article, thus: ἡ ἀγάπη ἡ μεθ᾿ ἡμῶν (Jh agaph Jh meq’ Jhmwn).

[4:17]  sn To say love is perfected with us means “with regard to our actions in loving our brothers.”

[4:17]  ⁶ tn Grk “that one” (a reference to Jesus is indicated in the context). Once more the author uses the pronoun ἐκεῖνος (ekeinos) to refer to Jesus Christ, as he did in 2:6; 3:3, 5, 7, and 16. A reference to Christ is confirmed in this context because the author says that “just as he is, so also are we [believers] in this world” and since 3:2 indicated that believers are to be like God in the future (but are not yet), the only one believers can be like already in the present age is Jesus Christ.
