1 John 2:16
Context2:16 because all that is in the world (the desire of the flesh and the desire of the eyes and the arrogance produced by material possessions) 1 is not from the Father, but is from the world.
1 John 4:3
Context4:3 but 2 every spirit that does not confess 3 Jesus 4 is not from God, and this is the spirit 5 of the antichrist, which you have heard is coming, and now is already in the world.
1 John 4:17
Context4:17 By this 6 love is perfected with 7 us, so that we may have confidence in the day of judgment, because just as Jesus 8 is, so also are we in this world.


[2:16] 1 tn The genitive βίου (biou) is difficult to translate: (1) Many understand it as objective, so that βίος (bios, “material life”) becomes the object of one’s ἀλαζονεία (alazoneia; “pride” or “boastfulness”). Various interpretations along these lines refer to boasting about one’s wealth, showing off one’s possessions, boasting of one’s social status or lifestyle. (2) It is also possible to understand the genitive as subjective, however, in which case the βίος itself produces the ἀλαζονεία. In this case, the material security of one’s life and possessions produces a boastful overconfidence. This understanding better fits the context here: The focus is on people who operate purely on a human level and have no spiritual dimension to their existence. This is the person who loves the world, whose affections are all centered on the world, who has no love for God or spiritual things (“the love of the Father is not in him,” 2:15).
[4:3] 2 tn The καί (kai) which begins 4:3 introduces the “negative side” of the test by which the spirits might be known in 4:2-3. Thus it is adversative in force: “every spirit that confesses Jesus as Christ who has come in the flesh is from God, but every Spirit that does not confess Jesus is not from God.”
[4:3] 3 tn Or “does not acknowledge.”
[4:3] 4 tc A number of variants are generated from the simple τὸν ᾿Ιησοῦν (ton Ihsoun), some of which turn the expression into an explicit object-complement construction. ᾿Ιησοῦν κύριον (Ihsoun kurion, “Jesus as Lord”) is found in א, τὸν ᾿Ιησοῦν Χριστόν (ton Ihsoun Criston, “Jesus as Christ”) is read by the Byzantine minuscules, τὸν Χριστόν (“the Christ”) is the reading of 1846, and ᾿Ιησοῦν without the article is found in 1881 2464. But τὸν ᾿Ιησοῦν is well supported by A B Ψ 33 81 1739 al, and internally best explains the rise of the others. It is thus preferred on both external and internal grounds.
[4:3] 5 tn “Spirit” is not in the Greek text but is implied.
[4:17] 3 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.
[4:17] 4 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).
[4:17] 5 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.
