1 John 2:3-4

Keeping God’s Commandments

2:3 Now ¹  by this we know that we have come to know God: ²  if we keep his commandments. 2:4 The one who says “I have come to know God” ³  and yet does not keep his commandments is a liar, and the truth is not in such a person.

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.

Psalms 91:14

91:14 The Lord says, ⁶ 

“Because he is devoted to me, I will deliver him;

I will protect him ⁷  because he is loyal to me. ⁸ 

Luke 10:22

10:22 All things have been given to me by my Father. ⁹  No one knows who the Son is except the Father, or who the Father is except the Son and anyone to whom the Son decides ¹⁰  to reveal him.”

John 8:19

8:19 Then they began asking ¹¹  him, “Who is your father?” Jesus answered, “You do not know either me or my Father. If you knew me you would know my Father too.” ¹² 

John 14:7

14:7 If you have known me, you will know my Father too. ¹³  And from now on you do know him and have seen him.”

John 17:3

17:3 Now this ¹⁴  is eternal life ¹⁵  – that they know you, the only true God, and Jesus Christ, ¹⁶  whom you sent.

[2:3]  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.

[2:3]  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.

[2:4]  ³ tn Grk “know him.” See the note on the phrase “know God” in 1 John 2:3 for explanation.

[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.

[91:14]  ⁶ tn The words “the Lord says” are supplied in the translation to clarify that the words which follow are the Lord’s oracle of assurance.

[91:14]  ⁷ tn Or “make him secure” (Heb “set him on high”).

[91:14]  ⁸ tn Heb “because he knows my name” (see Ps 9:10).

[10:22]  ⁹ sn This verse has been noted for its conceptual similarity to teaching in John’s Gospel (10:15; 17:2). The authority of the Son and the Father are totally intertwined.

[10:22]  ¹⁰ tn Or “wishes”; or “intends”; or “plans” (cf. BDAG 182 s.v. βούλομαι 2.b). Here it is the Son who has sovereignty.

[8:19]  ¹¹ tn Grk “Then they were saying to him.” The imperfect verb has been translated with ingressive force here because of the introduction of a new line of questioning by the Pharisees. Jesus had just claimed his Father as a second witness; now his opponents want to know who his father is.

[8:19]  ¹² sn If you knew me you would know my Father too. Jesus’ reply is based on his identity with the Father (see also John 1:18; 14:9).

[14:7]  ¹³ tc There is a difficult textual problem here: The statement reads either “If you have known (ἐγνώκατε, egnwkate) me, you will know (γνώσεσθε, gnwsesqe) my Father” or “If you had really known (ἐγνώκειτε, egnwkeite) me, you would have known (ἐγνώκειτε ἄν or ἂν ἤδειτε [egnwkeite an or an hdeite]) my Father.” The division of the external evidence is difficult, but can be laid out as follows: The mss that have the perfect ἐγνώκατε in the protasis (Ì⁶⁶ [א D* W] 579 pc it) also have, for the most part, the future indicative γνώσεσθε in the apodosis (Ì⁶⁶ א D W [579] pc sa bo), rendering Jesus’ statement as a first-class condition. The mss that have the pluperfect ἐγνώκειτε in the protasis (A B C D¹ L Θ Ψ Ë^1,13 33 Ï) also have, for the most part, a pluperfect in the apodosis (either ἂν ἤδειτε in B C* [L] Q Ψ 1 33 565 al, or ἐγνώκειτε ἄν in A C³ Θ Ë¹³ Ï), rendering Jesus’ statement a contrary-to-fact second-class condition. The external evidence slightly favors the first-class condition, since there is an Alexandrian-Western alliance supported by Ì⁶⁶. As well, the fact that the readings with a second-class condition utilize two different verbs with ἄν in different positions suggests that these readings are secondary. However, it could be argued that the second-class conditions are harder readings in that they speak negatively of the apostles (so K. Aland in TCGNT 207); in this case, the ἐγνώκειτε…ἐγνώκειτε ἄν reading should be given preference. Although a decision is difficult, the first-class condition is to be slightly preferred. In this case Jesus promises the disciples that, assuming they have known him, they will know the Father. Contextually this fits better with the following phrase (v. 7b) which asserts that “from the present time you know him and have seen him” (cf. John 1:18).

[17:3]  ¹⁴ tn Using αὕτη δέ (Jauth de) to introduce an explanation is typical Johannine style; it was used before in John 1:19, 3:19, and 15:12.

[17:3]  ¹⁵ sn This is eternal life. The author here defines eternal life for the readers, although it is worked into the prayer in such a way that many interpreters do not regard it as another of the author’s parenthetical comments. It is not just unending life in the sense of prolonged duration. Rather it is a quality of life, with its quality derived from a relationship with God. Having eternal life is here defined as being in relationship with the Father, the one true God, and Jesus Christ whom the Father sent. Christ (Χριστός, Cristos) is not characteristically attached to Jesus’ name in John’s Gospel; it occurs elsewhere primarily as a title and is used with Jesus’ name only in 1:17. But that is connected to its use here: The statement here in 17:3 enables us to correlate the statement made in 1:18 of the prologue, that Jesus has fully revealed what God is like, with Jesus’ statement in 10:10 that he has come that people might have life, and have it abundantly. These two purposes are really one, according to 17:3, because (abundant) eternal life is defined as knowing (being in relationship with) the Father and the Son. The only way to gain this eternal life, that is, to obtain this knowledge of the Father, is through the Son (cf. 14:6). Although some have pointed to the use of know (γινώσκω, ginwskw) here as evidence of Gnostic influence in the Fourth Gospel, there is a crucial difference: For John this knowledge is not intellectual, but relational. It involves being in relationship.

[17:3]  ¹⁶ tn Or “and Jesus the Messiah” (Both Greek “Christ” and Hebrew and Aramaic “Messiah” mean “one who has been anointed”).
