1 Yohanes 2:24

2:24 As for you, what you have heard from the beginning must remain ¹  in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.

1 Yohanes 3:3

3:3 And everyone who has this hope focused ²  on him purifies ³  himself, just as Jesus ⁴  is pure). ⁵ 

1 Yohanes 5:21

5:21 Little children, guard yourselves from idols. ⁶ 

[2:24]  ¹ tn The word translated “remain” may also be translated “reside” (3 times in 2:24). See also the notes on the translation of the Greek verb μένω (menw) in 2:6 and in 2:19. Here the word can really have both nuances of “residing” and “remaining” and it is impossible for the English reader to catch both nuances if the translation provides only one. This occurs three times in 2:24.

[3:3]  ² tn “Focused” is not in the Greek text, but is supplied for clarity.

[3:3]  ³ sn The verb translated purifies (ἁγνίζω, Jagnizw) is somewhat unusual here, since it is not common in the NT, and occurs only once in the Gospel of John (11:55). One might wonder why the author did not use the more common verb ἁγιάζω (Jagiazw), as in John 17:19, where Jesus prays, “On their behalf I consecrate myself, so that they may also be consecrated in the truth.” It is possible that there is some overlap between the two verbs and thus this is another example of Johannine stylistic variation, but the verb ἁγνίζω is used in the context of John 11:55, which describes ritual purification for the Passover, a usage also found in the LXX (Exod 19:10-11, Num 8:21). In this context the use of ἁγνίζω would remind the readers that, if they have the future hope of entering the Father’s presence (“seeing him as he is” in 3:2), they need to prepare themselves by living a purified lifestyle now, just as Jesus lived during his earthly life and ministry (cf. 2:6 again). This serves to rebut the opponents’ claims to moral indifference, that what the Christian does in the present life is of no consequence.

[3:3]  ⁴ tn Grk “that one.” Context indicates a reference to Jesus here. The switch from αὐτός (autos) to ἐκείνος (ekeinos) parallels 1 John 2:6 (see note there). Since purity of life is mentioned in the context, this almost certainly refers to Jesus in his earthly life and ministry as the example believers should imitate (a major theme of the author throughout 1 John).

[3:3]  ⁵ sn 1 John 3:1-3. All of 3:1-3 is a parenthesis within the present section in which the author reflects on what it means to be fathered by God, a subject he has mentioned at the end of 2:29. The sequence of the argument is then resumed by 3:4, which is in opposition to 2:29.

[5:21]  ⁶ tc Most later mss (P Ï) have ἀμήν (amhn, “amen”) at the end of this letter. Such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant. Further, the earliest and best witnesses, along with several others (א A B Ψ 33 323 630 1505 1739 al sy co), lack the inoffensive particle, rendering its omission as the authentic reading.

[5:21]  sn The modern reader may wonder what all this has to do with idolatry. In the author’s mind, to follow the secessionist opponents with their false Christology would amount to idolatry, since it would involve worshiping a false god instead of the true God, Jesus Christ. Thus guard yourselves from idols means for the readers to guard themselves against the opponents and their teaching.
