2:3 Now 1 by this we know that we have come to know God: 2 if we keep his commandments.
3:18 Little children, let us not love with word or with tongue but in deed and truth. 7
1 tn The translation of καί (kai) at the beginning of 2:3 is important for understanding the argument, because a similar καί occurs at the beginning of 1:5. The use here is not just a simple continuative or connective use, but has more of a resumptive force, pointing back to the previous use in 1:5.
2 tn Grk “know him.” (1) Many take the third person pronoun αὐτον (auton) to refer to Jesus Christ, since he is mentioned in 2:1 and the pronoun αὐτός (autos) at the beginning of 2:2 clearly refers to him. But (2) it is more likely that God is the referent here, since (a) the assurance the author is discussing here is assurance that one has come to know God (all the claims of the opponents in 1:5-2:11 concern knowing and having fellowship with the God who is light); (b) when Jesus Christ is explicitly mentioned as an example to follow in 1 John 2:6, the pronoun ἐκεῖνος (ekeinos) is used to distinguish this from previous references with αὐτός; (c) the καί (kai) which begins 2:3 is parallel to the καί which begins 1:5, suggesting that the author is now returning to the discussion of God who is light, a theme introduced in 1:5. The author will now discuss how a Christian may have assurance that he or she has come to know the God who is light.
3 tn The Greek verb μένω (menw) is commonly translated into contemporary English as “remain” or “abide,” but both of these translations have some problems: (1) “Abide” has become in some circles almost a “technical term” for some sort of special intimate fellowship or close relationship between the Christian and God, so that one may speak of Christians who are “abiding” and Christians who are not. It is accurate to say the word indicates a close, intimate (and permanent) relationship between the believer and God. However, it is very important to note that for the author of the Gospel of John and the Johannine Epistles every genuine Christian has this type of relationship with God, and the person who does not have this type of relationship (cf. 2 John 9) is not a believer at all (in spite of what he or she may claim). (2) On the other hand, to translate μένω as “remain” removes some of these problems, but creates others: In certain contexts, such a translation can give the impression that those who currently “remain” in this relationship with God can at some point choose not to “remain”, that is, to abandon their faith and return to an unsaved condition. While one may easily think in terms of the author’s opponents in 1 John as not “remaining,” the author makes it inescapably clear in 2:19 that these people, in spite of their claims to know God and be in fellowship with God, never really were genuine believers. (3) In an attempt to avoid both these misconceptions, this translation renders μένω as “reside” except in cases where the context indicates that “remain” is a more accurate nuance, that is, in contexts where a specific change of status or movement from one position to another is in view.
4 tn Grk “in him.” Context indicates a reference to God since a different pronoun, ἐκεινος (ekeinos), is used later in the same verse to indicate a reference to Jesus. See the note on “Jesus” later in this verse.
5 tn That is, ought to behave in the same way Jesus did. “Walking” is a common NT idiom for one’s behavior or conduct.
6 tn Grk “that one.” Context indicates a reference to Jesus here. It is clear that ἐκεῖνος (ekeinos) here does not refer to the same person as αὐτῷ (autw) in 2:6a. The switch to ἐκεῖνος indicates a change in the referent, and a reference to Jesus Christ is confirmed by the verb περιεπάτησεν (periepathsen), an activity which can only describe Jesus’ earthly life and ministry, the significance of which is one of the points of contention the author has with the opponents. In fact, ἐκεῖνος occurs 6 times in 1 John (2:6; 3:3, 5, 7, 16; and 4:17), and each one refers to Jesus Christ.
5 sn The noun truth here has been interpreted in various ways: (1) There are a number of interpreters who understand the final noun in this series, truth (ἀληθείᾳ, alhqeia) in an adverbial sense (“truly” or “in sincerity”), describing the way in which believers are to love. If the two pairs of nouns are compared, however, it is hard to see how the second noun with tongue (γλώσσῃ, glwssh) in the first pair can have an adverbial sense. (2) It seems better to understand the first noun in each pair as produced by the second noun: Words are produced by the tongue, and the (righteous) deeds with which believers are to love one another are produced by the truth.
7 tn Both ἐγνώκαμεν (egnwkamen) and πεπιστεύκαμεν (pepisteukamen) in 4:16 are perfect tenses, implying past actions with existing results. In this case the past action is specified as the recognition of (ἐγνώκαμεν) and belief in (πεπιστεύκαμεν) “the love which God has in us.” But what is the relationship between the two verbs γινώσκω (ginwskw) and πιστεύω (pisteuw)? (1) Some interpreters would see a different nuance in each. (2) But in the Gospel of John the two verbs frequently occur together in the same context, often in the same tense; examples may be found in John 6:69, 8:31-32, 10:38, 14:7-10, and 17:8. They also occur together in one other context in 1 John, 4:1-2. Of these John 6:69, Peter’s confession, is the closest parallel to the usage here: “We have come to believe [πεπιστεύκαμεν] and to know [ἐγνώκαμεν] that you are the holy One of God.” Here the order between “knowing” and “believing” is reversed from 1 John 4:16, but an examination of the other examples from the Gospel of John should make it clear that there is no difference in meaning when the order of the terms is reversed. It appears that the author considered both terms to describe a single composite action. Thus they represent a hendiadys which describes an act of faith/belief/trust on the part of the individual; knowledge (true knowledge) is an inseparable part of this act of faith.
8 tn The force of the preposition ἐν (en) in the phrase ἐν ἡμῖν (en Jhmin) in 4:16a is disputed: Although (1) “for” (in the sense of “on behalf of”) is possible and is a common English translation, the other uses of the same phrase in 4:9 (where it refers to God’s love for us) and 4:12 (where it refers to God’s indwelling of the believer) suggest that (2) the author intends to emphasize interiority here – a reference to God’s love expressed in believers. This is confirmed by the only other uses in 1 John of the verb ἔχω (ecw) with the preposition ἐν (3:15 and 5:10) both of which literally mean something in someone.
9 tn Once again μένω (menw) in its three occurrences in 4:16 looks at the mutual state of believers and God. No change of status or position is in view in the context, so the participle and both finite verbs are translated as “resides.”
