[3:19]  ¹ tn Once again there is the problem of deciding whether the phrase ἐν τούτῳ (en toutw) refers (1) to what precedes or (2) to what follows. When an explanatory or epexegetical ὅτι (Joti) clause follows, and the ὅτι clause is not grammatically unrelated to the phrase ἐν τούτῳ, then the ἐν τούτῳ is best understood as referring to what follows. Here in 3:19-20 there are no less than three ὅτι clauses that follow, one in 3:19 and two in 3:20, and thus there is the difficulty of trying to determine whether any one of them is related to the ἐν τούτῳ phrase in 3:19. It is relatively easy to eliminate the first ὅτι clause (in 3:19) from consideration, because it is related not to ἐν τούτῳ but to the verb γνωσόμεθα (gnwsomeqa) as an indirect discourse clause giving the content of what believers know (“that we are of the truth”). As far as the two ὅτι clauses in 3:20 are concerned, it is difficult to see how believers could know that they belong to the truth (19a) by means of either, since the first speaks of a situation where they are under self-condemnation (“if our heart condemns us…”) and the second ὅτι clause seems to give a further explanation related to the first (“that God is greater than our heart…”). Therefore it seems better to understand the phrase ἐν τούτῳ in 3:19 as referring to the preceding context, and this makes perfectly good sense, because 3:18 concludes with a reference to the righteous deeds with which believers are to love one another, which are produced by the truth.

[3:19]  ² tn The verb πείθω (peiqw) in the active voice (with the exception of the second perfect and pluperfect) means (a) “to convince”; (b) “to persuade, appeal to”; (c) “to win over, strive to please”; or (d) “to conciliate, pacify, set at ease or rest” (see BDAG 791 s.v. πείθω). Interpreters are generally divided between meaning (a) and meaning (d) for the verb in the present context, with BDAG opting for the latter (although it is pointed out that “the text is not in good order”). In any case the object of the verb πείθω in this context is καρδία (kardia), and this leads to further problems because the meaning of καρδία will affect one’s understanding of πείσομεν (peisomen) here.

[3:19]  ³ tn Further difficulties are created by the meaning of καρδία (kardia) in 3:19. Although it may be agreed that the term generally refers to the “center and source of the whole inner life, w. its thinking, feeling, and volition” (BDAG 508 s.v. l.b), this may be further subdivided into references to (a) “the faculty of thought…as the organ of natural and spiritual enlightenment,” that is, the mind; (b) “the will and its decisions”; (c) “the emotions, wishes, desires,” i.e., the emotions or feelings; or (d) “moral decisions, the moral life,” that is, the part of the individual where moral decisions are made, which is commonly called the conscience. Thus καρδία in 3:19 could refer to either the mind, the will, the emotions, or the conscience, and it is not transparently clear which concept the author has primarily in view. In light of the overall context, which seems to discuss the believer’s assurance of his or her standing before God (ἔμπροσθεν αὐτοῦ [emprosqen autou] in 3:19 and the mention of παρρησία [parrhsia, “boldness” or “confidence”] in 3:21) it seems probable that the conscience, that aspect of one’s καρδία which involves moral choices and the guilt or approval for having made them, is primarily in view here. Thus the meaning “convince” is preferred for the verb πείθω (peiqw), since the overall subject seems to be the believer’s assurance of his or her standing before God, especially in the case when (v. 20) the believer’s conscience attempts to condemn him on account of sin.

[3:19]  ⁴ tn Both ἔμπροσθεν (emprosqen) in 3:19 and ἐνώπιον (enwpion) in 3:22 are improper prepositions and both express the meaning “before” in the sense of “in the presence of.” (1) Some interpreters have tried to see a subtle distinction in meaning between the two in 3:19 and 22, but (2) as BDF §214.6 points out, ἔμπροσθεν and ἐνώπιον, along with a third classical expression ἐναντίον (enantion), all refer to being in someone’s presence and are essentially interchangeable. There can be little doubt that once more the author’s fondness for stylistic variation in terminology is at work here.

[5:19]  ⁵ tn The preposition ἐκ (ek) here indicates both source and possession: Christians are “from” God in the sense that they are begotten by him, and they belong to him. For a similar use of the preposition compare the phrases ἐκ τοῦ πατρός (ek tou patro") and ἐκ τοῦ κόσμου (ek tou kosmou) in 1 John 2:16.

[2:5]  ⁹ tn The referent of this pronoun is probably to be understood as God, since God is the nearest previous antecedent.

[2:5]  ¹⁰ tn Grk “in him.”

[3:1]  ¹³ 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]  ¹⁴ tn “Indeed” is not in the Greek text but is supplied to indicate emphasis.

[3:1]  ¹⁵ 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]  ¹⁶ 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]  ¹⁷ sn The pronoun him is a clear reference to Jesus Christ (compare John 1:10).

[3:2]  ¹⁷ tn The subject of the third person singular passive verb ἐφανερώθη (efanerwqh) in 3:2 is the following clause τί ἐσόμεθα (ti esomeqa): “Beloved, now we are children of God, and what we shall be has not yet been revealed.”

[3:2]  ¹⁸ tc The Byzantine text, the Syriac Peshitta, the Bohairic Coptic, and one ms of the Sahidic Coptic supply δέ (de) after οἴδαμεν (oidamen) in 3:2b. Additions of coordinating conjunctions such as δέ are predictable variants; this coupled with the poor external credentials suggests that this addition is not likely to be original.

[3:2]  ¹⁹ tn The first ὅτι (Joti) in 3:2 follows οἴδαμεν (oidamen), a verb of perception, and introduces an indirect discourse clause which specifies the content of what believers know: “that whenever it should be revealed, we shall be like him.”

[3:2]  ²⁰ tn In this context ἐάν (ean) does not indicate (1) uncertainty about whether or not what believers will be shall be revealed, but rather (2) uncertainty about the exact time the event will take place. In the Koine period ἐάν can mean “when” or “whenever” and is virtually the equivalent of ὅταν (Jotan; see BDAG 268 s.v. ἐάν 2). It has this meaning in John 12:32 and 14:3. Thus the phrase here should be translated, “we know that whenever it is revealed.”

[3:2]  ²¹ tn Many take the understood subject (“he”) of φανερωθῇ (fanerwqh) as a reference to Jesus Christ, because the same verb was used in 2:28 in reference to the parousia (second advent). In the immediate context, however, a better analogy is ἐφανερώθη τί ἐσόμεθα (efanerwqh ti esomeqa) in 3:2a. There the clause τί ἐσόμεθα is the subject of the passive verb: “what we shall be has not yet been revealed.” From a grammatical standpoint it makes better sense to see the understood subject of φανερωθῇ as “it” rather than “he” and as referring back to the clause τί ἐσόμεθα in 3:2a. In the context this makes good sense: “Beloved, now we are children of God, and what we shall be has not yet been revealed. We know that whenever it shall be revealed, we shall be like him, because we shall see him just as he is.” This emphasizes the contrast in the verse between the present state (“not yet been revealed”) and the future state (“shall be revealed”) of believers, and this will of course take place at the parousia.

[3:2]  ²² sn Is revealed. It may well be that the use of the same passive verb here (from φανερόω, fanerow) is intended to suggest to the reader the mention of the parousia (Christ’s second coming) in 2:28.

[3:2]  ²³ tn The second ὅτι (Joti) in 3:2 is best understood as causal, giving the reason why believers will be like God: “we shall be like him, because we shall see him just as he is.”

[3:2]  ²⁴ sn The phrase we will be like him, because we will see him just as he is has been explained two ways: (1) believers will really become more like God than they now are, and will do this through seeing God as he really is; or (2) believers will realize that they are already like God, but did not realize it until they see him as he is. One who sees a strong emphasis on realized eschatology in the Gospel of John and the Epistles might opt for the second view, since it downplays the difference between what believers already are in the present age and what they will become in the next. It seems better, though, in light of the statement in 3:2a that “what we will be has not yet been revealed” and because of the reference to Christ’s parousia in 2:28, that the author intends to distinguish between the present state of believers and what they will be like in the future. Thus the first view is better, that believers really will become more like God than they are now, as a result of seeing him as he really is.

[4:17]  ²¹ 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]  ²² 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]  ²³ 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.

[4:6]  ²⁵ tn “But” supplied here to bring out the context. The conjunction is omitted in the Greek text (asyndeton).

[4:6]  ²⁶ tn The phrase ἐκ τούτου (ek toutou) in 4:6, which bears obvious similarity to the much more common phrase ἐν τούτῳ (en toutw), must refer to what precedes, since there is nothing in the following context for it to relate to, and 4:1-6 is recognized by almost everyone as a discrete unit. There is still a question, however, of what in the preceding context the phrase refers to. Interpreters have suggested a reference (1) only to 4:6; (2) to 4:4-6; or (3) to all of 4:1-6. The last is most likely, because the present phrase forms an inclusion with the phrase ἐν τούτῳ in 3:24 which introduces the present section. Thus “by this we know the Spirit of truth and the spirit of deceit” refers to all of 4:1-6 with its “test” of the spirits by the christological confession made by their adherents in 4:1-3 and with its emphasis on the authoritative (apostolic) eyewitness testimony to the significance of Jesus’ earthly life and ministry in 4:4-6.

[4:6]  ²⁷ sn Who or what is the Spirit of truth and the spirit of deceit in 1 John 4:6? (1) Some interpreters regard the “spirits” in 4:6 as human spirits. Although 4:1a is ambiguous and might refer either to human spirits or spiritual beings who influence people, it is clear in the context that (2) the author sees behind the secessionist opponents with their false Christology the spirit of the Antichrist, that is, Satan (4:3b), and behind the true believers of the community to which he is writing, the Spirit of God (4:2). This is made clear in 4:4 by the reference to the respective spirits as the One who is in you and the one who is in the world.

[5:20]  ²⁹ tn The ἵνα (Jina) introduces a purpose clause which gives the purpose of the preceding affirmation: “we know that the Son of God has come and has given us insight (so that we may) know him who is true.”

[5:20]  ³⁰ sn The pronoun This one (οὗτος, Joutos) refers to a person, but it is far from clear whether it should be understood as a reference (1) to God the Father or (2) to Jesus Christ. R. E. Brown (Epistles of John [AB], 625) comments, “I John, which began with an example of stunning grammatical obscurity in the prologue, continues to the end to offer us examples of unclear grammar.” The nearest previous antecedent is Jesus Christ, immediately preceding, but on some occasions when this has been true the pronoun still refers to God (see 1 John 2:3). The first predicate which follows This one in 5:20, the true God, is a description of God the Father used by Jesus in John 17:3, and was used in the preceding clause of the present verse to refer to God the Father (him who is true). Yet the second predicate of This one in 5:20, eternal life, appears to refer to Jesus, because although the Father possesses “life” (John 5:26, 6:57) just as Jesus does (John 1:4, 6:57, 1 John 5:11), “life” is never predicated of the Father elsewhere, while it is predicated of Jesus in John 11:25 and 14:6 (a self-predication by Jesus). If This one in 5:20 is understood as referring to Jesus, it forms an inclusion with the prologue, which introduced the reader to “the eternal life which was with the Father and was manifested to us.” Thus it appears best to understand the pronoun This one in 5:20 as a reference to Jesus Christ. The christological affirmation which results is striking, but certainly not beyond the capabilities of the author (see John 1:1 and 20:28): This One [Jesus Christ] is the true God and eternal life.
