1 John 2:29

2:29 If you know that he is righteous, you also know ¹  that everyone who practices righteousness has been fathered ²  by him.

1 John 3:7

3:7 Little children, let no one deceive you: The one who practices righteousness ³  is righteous, just as Jesus ⁴  is righteous.

1 John 3:10

3:10 By this ⁵  the children of God and the children of the devil are revealed: Everyone who does not practice righteousness – the one who does not love his fellow Christian ⁶  – is not of God.

[2:29]  ¹ tn The mood of γινώσκετε (ginwskete) may be understood as (1) indicative or (2) imperative. It is better to understand the verb here as indicative, because in 1 John “knowledge” is something one has as a result of being a believer (2:3, 5, 20, 21; 3:16, 19, 24; 4:2, 13; 5:2) rather than something one has to be exhorted about. The change in verbs from οἶδα (oida) to γινώσκω (ginwskw) is another example of Johannine stylistic variation.

[2:29]  ² tn The verb γεννάω (gennaw) presents a translation problem: (1) should the passive be translated archaically “be begotten” (the action of the male parent; see BDAG 193 s.v. 1.a) or (2) should it be translated “be born” (as from a female parent; see BDAG 194 s.v. 2)? A number of modern translations (RSV, NASB, NIV) have opted for the latter, but (3) the imagery expressed in 1 John 3:9 clearly refers to the action of the male parent in procreating a child, as does 5:1 (“everyone who loves the father loves the child fathered by him”), and so a word reflecting the action of the male parent is called for here. The contemporary expression “fathered by” captures this idea.

[3:7]  ³ sn The one who practices righteousness. The participle (ὁ ποιῶν, Jo poiwn) + noun constructions in 3:7 and in 3:8a, the first positive and the second negative, serve to emphasize the contrast between the true Christians (“the one who practices righteousness”) and the opponents (“the one who practices sin,” 3:8a).

[3:7]  ⁴ tn Grk “that one.” Context indicates a reference to Jesus here. As with the previous uses of ἐκεῖνος (ekeinos) by the author of 1 John (2:6; 3:3, 5), this one refers to Jesus, as the reference to “the Son of God” in the following verse (3:8) makes clear.

[3:10]  ⁵ tn Once again there is the problem (by now familiar to the interpreter of 1 John) of determining whether the phrase ἐν τούτῳ (en toutw) in 3:10 refers (1) to what precedes or (2) to what follows. If it refers to what precedes, it serves to conclude the unit which began with 2:28. The remainder of 3:10 would then form a transition to the following material (another “hinge” passage). On the other hand, if the phrase ἐν τούτῳ refers to what follows, then the entirety of 3:10 is a summary statement at the end of 2:28-3:10 which recapitulates the section’s major theme (conduct is the clue to paternity), and provides at the same time a transition to the theme of loving one’s brother which will dominate the following section (3:11-24). Although R. E. Brown (Epistles of John [AB], 416) prefers to see the phrase as referring to the preceding material, it makes better sense to refer it to the remainder of 3:10 that follows, and see the entirety of 3:10 as both a summary of the theme of the preceding section 2:28-3:10 and a transition to the following section 3:11-24.

[3:10]  ⁶ tn See note on the term “fellow Christian” in 2:9.
