1 John 2:23-24

2:23 Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also. ¹ 

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

1 John 4:10

4:10 In this ³  is love: not that ⁴  we have loved God, but that he loved us and sent his Son to be the atoning sacrifice ⁵  for our sins.

[2:23]  ¹ tc The Byzantine text, almost alone, lacks the last eight words of this verse, “The person who confesses the Son has the Father also” (ὁ ὁμολογῶν τὸν υἱὸν καὶ τὸν πατέρα ἔχει, Jo Jomologwn ton Juion kai ton patera ecei). Although shorter readings are often preferred (since scribes would tend to add material rather than delete it), if an unintentional error is likely, shorter readings are generally considered secondary. This is a classic example of such an unintentional omission: The τὸν πατέρα ἔχει of the preceding clause occasioned the haplography, with the scribe’s eye skipping from one τὸν πατέρα ἔχει to the other. (Readings such as this also suggest that the Byzantine text may have originated [at least for 1 John and probably the general epistles] in a single archetype.)

[2:24]  ² 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.

[4:10]  ³ tn Once again there is the (by now familiar) problem of determining whether the referent of this phrase (1) precedes or (2) follows. Here there are two ὅτι (Joti) clauses which follow, both of which are epexegetical to the phrase ἐν τούτῳ (en toutw) and explain what the love of God consists of: first, stated negatively, “not that we have loved God,” and then positively, “but that he loved us and sent his Son to be the atoning sacrifice for our sins.”

[4:10]  ⁴ tn The two ὅτι (Joti) clauses are epexegetical to the phrase ἐν τούτῳ (en toutw) which begins the verse.

[4:10]  ⁵ sn As explained at 2:2, inherent in the meaning of the word translated atoning sacrifice (ἱλασμός, Jilasmos) is the idea of turning away the divine wrath, so that “propitiation” is the closest English equivalent. God’s love for us is expressed in his sending his Son to be the propitiation (the propitiatory sacrifice) for our sins on the cross. This is an indirect way for the author to allude to one of the main points of his controversy with the opponents: the significance for believers’ salvation of Jesus’ earthly life and ministry, including especially his sacrificial death on the cross. The contemporary English “atoning sacrifice” communicates this idea more effectively.
