¹ tn The context of this statement in 1:6 indicates clearly that the progressive (continuative or durative) aspect of the present tense must be in view here.

sn The relationship of the phrase keep on walking to if we say is very important for understanding the problem expressed in 1:6. If one should say (εἴπωμεν, eipwmen) that he has fellowship with God, and yet continues walking (περιπατῶμεν, peripatwmen) in the darkness, then it follows (in the apodosis, the “then” clause) that he is lying and not practicing the truth.

² tn Or “living according to…”

³ tn “In him” probably refers to Jesus Christ since the last third person pronoun in 2:6 referred to Jesus Christ and there is no indication in the context of a change in referent.

⁴ tn The clause beginning with ὅτι (Joti) is often taken as (1) epexegetical or (2) appositional to the commandment (ἐντολήν, entolhn) giving a further explanation or clarification of it. But the statement following the ὅτι is about light and darkness, and it is difficult to see how this has anything to do with the commandment, especially as the commandment is related to the “new commandment” of John 13:34 for believers to love one another. It is far more likely that (3) the ὅτι clause should be understood as causal, but this still does not answer the question of whether it offers the reason for writing the “new commandment” itself or the reason for the relative clause (“that is true in him and in you”). It probably gives the reason for the writing of the commandment, although R. E. Brown (Epistles of John [AB], 268) thinks it refers to both.

⁵ sn The reference to the darkness…passing away and the true light…already shining is an allusion to John 1:5, 1:9, and 8:12. Because the author sees the victory of light over darkness as something already begun, he is writing Jesus’ commandment to love one another to the readers as a reminder to (1) hold fast to what they have already heard (see 1 John 2:7) and (2) not be influenced by the teaching of the opponents.

⁶ tn Here the phrase ἐν τούτῳ (en toutw) is followed by a ὅτι (Joti) clause which is epexegetical (or explanatory), and thus ἐν τούτῳ refers to what follows.

⁷ tn Grk “that one.” Context indicates a reference to Jesus. The mention of the sacrificial death in 3:16 (ὑπὲρ ἡμῶν τὴν ψυχὴν αὐτοῦ ἔθηκεν, Juper hmwn thn yuchn autou eqhken) points to Jesus as the referent here. (This provides further confirmation that ἐκεῖνος [ekeinos] in 2:6; 3:3, 5, and 7 refers to Jesus.)

⁸ sn References to the fact that Jesus laid down his life using the verb τίθημι (tiqhmi) are unique to the Gospel of John (10:11, 15, 17, 18; 13:37, 38; 15:13) and 1 John (only here). From John’s perspective Jesus’ act in giving up his life sacrificially was a voluntary one; Jesus was always completely in control of the situation surrounding his arrest, trials, and crucifixion (see John 10:18). There is a parallel with 1 John 2:6 – there, as here, the life of Jesus (during his earthly ministry) becomes the example for believers to follow. This in turn underscores the importance of Jesus’ earthly life and ministry (especially his sacrificial death on the cross), a point of contention between the author and his opponents in 1 John. See 1 John 4:10 for a further parallel.

⁹ tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.

¹⁰ tn This verse begins with the phrase καὶ αὕτη ἐστίν (kai {auth estin; cf. the similar phrase in 3:11 and 1:5), which is explained by the following ἵνα (Jina) clause, “that we believe in the name of his Son Jesus Christ.” The ἵνα thus introduces a clause which is (1) epexegetical (explanatory) or (2) appositional. By analogy the similar phrase in 3:11 is also followed by an epexegetical ἵνα clause and the phrase in 1:5 by an epexegetical ὅτι (Joti) clause.

sn His commandment refers to what follows – the commandment from God is to believe in his Son, Jesus Christ, and to love one another.

¹¹ sn The author of 1 John repeatedly attributes the commandments given to believers as given by God the Father, even though in John 13:34-35 it was Jesus who gave the commandment to love one another. 2 John 4-5 also attributes the commandment to love one another directly to the Father. Thus it is clear that God the Father is the subject of the verb gave here in 3:23.

¹² 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.

¹³ 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).

sn To say love is perfected with us means “with regard to our actions in loving our brothers.”

¹⁴ 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.

¹⁵ tn For the third time in 5:9-14 the author uses the construction αὕτη ἐστίν ({auth estin; 5:9, 11, 14). As in the previous instance (5:11) the ὅτι (Joti) clause which follows is epexegetical (explanatory) to the pronoun αὕτη and explains what the “confidence” (παρρησία, parrhsia) consists of (technically the subject is ἡ παρρησία, the predicate nominative is the pronoun αὕτη, and the ὅτι clause explains the predicate nominative): “And the confidence which we have before him is this, namely, that if we ask anything according to his will he hears us.”

¹⁶ tn A third-class condition is introduced by ἐάν (ean) + present subjunctive. Because the apodosis also contains a present tense verb (ἀκούει, akouei) this belongs in a subcategory of third-class conditional sentences known as present general. 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). Thus the meaning here is, “whenever (i.e., if) we ask anything according to his will, then he hears us.”
