4:9 By this 1 the love of God 2 is revealed in us: 3 that God has sent his one and only 4 Son into the world so that we may live through him. 4:10 In this 5 is love: not that 6 we have loved God, but that he loved us and sent his Son to be the atoning sacrifice 7 for our sins.

1 tn Once again there is the problem of determining whether the phrase ἐν τούτῳ (en toutw) refers (1) to what precedes or (2) to what follows. This is the first of 5 uses of the phrase in the present section (4:9, 10, 13, 17; 5:2). In this case (as also in the next two instances) there is a ὅτι (Joti) clause following which is related and which explains (i.e., which is epexegetical to) the phrase ἐν τούτῳ. Thus the meaning here is, “By this the love of God is revealed in us: that God has sent his only Son into the world in order that we might live through him.”
2 tn In terms of syntax the force of the genitive τοῦ θεοῦ (tou qeou) may be (1) objective, (2) subjective, or (3) both. The phrase occurs for the first time in the letter in 2:5. Here in 4:9 the epexegetical ὅτι (Joti) clause which follows makes it clear that this is a subjective genitive, emphasizing God’s love for us rather than our love for God, because it describes God’s action in sending his Son into the world.
3 tn This phrase is best understood as the equivalent of a dative of sphere, but this description does not specify where the love of God is revealed with regard to believers: “in our midst” (i.e., among us) or “within us” (i.e., internally within believers). The latter is probable, because in the context the concept of God’s indwelling of the believer is mentioned in 4:12: “God resides (μένει, menei) in us.”
4 sn Although the word translated one and only (μονογενής, monogenhs) is often rendered “only begotten,” such a translation is misleading, since in English it appears to express a metaphysical relationship. The word in Greek was used of an only child (a son [Luke 7:12, 9:38] or a daughter [Luke 8:42]). It was also used of something unique (only one of its kind) such as the mythological bird called the Phoenix (1 Clement 25:2). From here it passes easily to a description of Isaac (Heb 11:17 and Josephus, Ant. 1.13.1 [1.222]) who was not Abraham’s only son, but was one-of-a-kind because he was the child of the promise. Thus the word means “one-of-a-kind” and is reserved for Jesus alone in the Johannine literature of the NT. While all Christians are children of God (τέκνα θεοῦ, tekna qeou), Jesus is God’s Son in a unique, one-of-a-kind sense. The word is used in this way in all its uses in the Gospel of John (1:14, 18; 3:16, 18).
5 tn Once again there is the (by now familiar) problem of determining whether the referent of this phrase (1) precedes or (2) follows. Here there are two ὅτι (Joti) clauses which follow, both of which are epexegetical to the phrase ἐν τούτῳ (en toutw) and explain what the love of God consists of: first, stated negatively, “not that we have loved God,” and then positively, “but that he loved us and sent his Son to be the atoning sacrifice for our sins.”
6 tn The two ὅτι (Joti) clauses are epexegetical to the phrase ἐν τούτῳ (en toutw) which begins the verse.
sn What is important (as far as the author is concerned) is not whether we love God (or say that we love God – a claim of the opponents is probably behind this), but that God has loved us and sent his Son to be the atoning sacrifice which removes believers’ sins. This latter point is similar to the point made in 2:2 and is at the heart of the author’s dispute with the opponents, because they were denying any salvific value to Jesus’ earthly life and ministry, including his death on the cross.
7 sn As explained at 2:2, inherent in the meaning of the word translated atoning sacrifice (ἱλασμός, Jilasmos) is the idea of turning away the divine wrath, so that “propitiation” is the closest English equivalent. God’s love for us is expressed in his sending his Son to be the propitiation (the propitiatory sacrifice) for our sins on the cross. This is an indirect way for the author to allude to one of the main points of his controversy with the opponents: the significance for believers’ salvation of Jesus’ earthly life and ministry, including especially his sacrificial death on the cross. The contemporary English “atoning sacrifice” communicates this idea more effectively.
8 tn Again whether the referent of the phrase ἐν τούτῳ (en toutw) (1) precedes or (2) follows is a problem. This time there are two ὅτι (Joti) clauses which follow. The first is an indirect discourse clause related to γινώσκομεν (ginwskomen) and giving the content of what believers know: “that we reside in him and he in us.” The second ὅτι clause is epexegetical (or explanatory) to the ἐν τούτῳ phrase, explaining how believers know that they reside in God and God remains in them: “in that he has given us of his Spirit.”
sn By this we know. According to the author of 1 John, the Father’s giving of the indwelling Holy Spirit to the believer is one means of providing assurance to the believer of his relationship to God. This is what was also stated in 1 John 3:24b in essentially identical terms.
10 sn The genitive of his Spirit here, like the phrase in 3:24, probably reflects a partitive nuance, so that the author portrays God as ‘apportioning’ his Spirit to individual believers. This leads to the important observation that the author is not particularly interested in emphasizing (1) the ongoing interior witness of the Holy Spirit (which is what the passage is often understood to mean) but is emphasizing (2) the fact that God has given the Spirit to believers, and it is this fact that gives believers assurance of their relationship to God. In other words, it is the fact that the Holy Spirit has been given to believers, rather than the ongoing interior testimony of the Holy Spirit within the believer, which is the primary source of the believer’s assurance.
11 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.
12 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.”
13 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.
14 tn Once more there is the familiar difficulty of determining whether the phrase refers (1) to what precedes or (2) to what follows. Here, because ἐν τούτῳ (en toutw) is followed by a clause introduced by ὅταν (Jotan) which appears to be related, it is best to understand ἐν τούτῳ as referring to what follows. The following ὅταν clause is epexegetical to ἐν τούτῳ, explaining how we know that we love God’s children: “by this we know that we love God’s children, whenever we love God and keep his commandments.”
