1 John 2:24

2:24 As for you, what you have heard from the beginning must remain ¹  in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.

1 John 3:1

3:1 (See what sort of love the Father has given to us: that ²  we should be called God’s children – and indeed ³  we are! ⁴  For this reason ⁵  the world does not know us: because it did not know him. ⁶ 

1 John 3:12

3:12 not like Cain ⁷  who was of the evil one and brutally ⁸  murdered his brother. And why did he murder him? Because his deeds were evil, but his brother’s were righteous.

1 John 4:17

4:17 By this ⁹  love is perfected with ¹⁰  us, so that we may have confidence in the day of judgment, because just as Jesus ¹¹  is, so also are we in this world.

1 John 4:20

4:20 If anyone says ¹²  “I love God” and yet ¹³  hates his fellow Christian, ¹⁴  he is a liar, because the one who does not love his fellow Christian ¹⁵  whom he has seen cannot love God whom he has not seen. ¹⁶ 

[2:24]  ¹ tn The word translated “remain” may also be translated “reside” (3 times in 2:24). See also the notes on the translation of the Greek verb μένω (menw) in 2:6 and in 2:19. Here the word can really have both nuances of “residing” and “remaining” and it is impossible for the English reader to catch both nuances if the translation provides only one. This occurs three times in 2:24.

[3:1]  ² tn The ἵνα (Jina) clause is best understood (1) as epexegetical (or explanatory), clarifying the love (ἀγάπην, agaphn) that the Father has given to believers. Although it is possible (2) to regard the ἵνα as indicating result, the use of ποταπήν (potaphn, “what sort of”) to modify ἀγάπην suggests that the idea of “love” will be qualified further in the following context, and this qualification is provided by the epexegetical ἵνα clause.

[3:1]  ³ tn “Indeed” is not in the Greek text but is supplied to indicate emphasis.

[3:1]  ⁴ tc The phrase καὶ ἐσμεν (kai esmen, “and we are”) is omitted in 049 69 Ï. There seems to be no theological reason to omit the words. This has all the earmarks of a classic case of homoioteleuton, for the preceding word (κληθῶμεν, klhqwmen, “we should be called”) ends in -μεν (-men).

[3:1]  ⁵ tn Lexically it is clear that this phrase indicates reason, but what is not clear is whether (1) τοῦτο (touto) refers to what follows, (2) to what precedes, or (3) to both (as with the ἐν τοῦτο [en touto] phrases throughout 1 John). Διὰ τοῦτο (dia touto) occurs 15 times in the Gospel of John, and a pattern emerges which is so consistent that it appears to be the key to the usage here. Six times in the Gospel of John (5:16, 18; 8:47; 10:17; 12:18, 39) the phrase refers to what follows, and in each of these instances an epexegetical ὅτι (Joti) clause follows. Nine times in John (1:31, 6:65, 7:21-22, 9:23, 12:27, 13:11, 15:19, 16:15, 19:11) the phrase refers to what precedes, and in none of these instances is it followed by a ὅτι clause. The phrase διὰ τοῦτο is used three times in the Johannine Epistles. In two of these (1 John 4:5, 3 John 10) there is no ὅτι clause following, and so the διὰ τοῦτο should refer to preceding material. Here in 3:1 there is an epexegetical ὅτι clause following, so the διὰ τοῦτο should (unless it is the only exception in the Gospel of John and the Johannine Epistles) refer to what follows, that is, to the ὅτι clause itself. This is indicated by the colon in the translation.

[3:1]  ⁶ sn The pronoun him is a clear reference to Jesus Christ (compare John 1:10).

[3:12]  ³ 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]  ⁴ 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]  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.

[4:20]  ⁵ tn Grk “if anyone should say…”

[4:20]  ⁶ tn “Yet” is supplied to bring out the contrast.

[4:20]  ⁷ tn See note on the phrase “fellow Christian” in 2:9.

[4:20]  ⁸ tn See note on the phrase “fellow Christian” in 2:9.

[4:20]  ⁹ sn In 4:20 the author again describes the opponents, who claim to love God. Their failure to show love for their fellow Christians proves their claim to know God to be false: The one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.
