1 John 4:16

4:16 And we have come to know and to believe ¹  the love that God has in us. ²  God is love, and the one who resides ³  in love resides in God, and God resides in him.

1 John 5:20

5:20 And we know that the Son of God has come and has given us insight to know ⁴  him who is true, and we are in him who is true, in his Son Jesus Christ. This one ⁵  is the true God and eternal life.

[4:16]  ¹ 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.

[4:16]  ² 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.

[4:16]  ³ 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.”

[5:20]  ⁴ 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]  ⁵ 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.
