Discovery Box1 John 3:9-10 
Context3:9 Everyone who has been fathered 1 by God does not practice sin, 2 because 3 God’s 4 seed 5 resides in him, and thus 6 he is not able to sin, because he has been fathered by God. 3:10 By this 7 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 8 – is not of God.
1 tn The imagery expressed here (σπέρμα αὐτοῦ, sperma autou, “his seed”) clearly refers to the action of the male parent in procreation, and so “fathered” is the best choice for translating γεννάω (gennaw; see 2:29).
2 tn The problem of the present tense of ποιεῖ (poiei) here is exactly that of the present tense of ἁμαρτάνει (Jamartanei) in 3:6. Here in 3:9 the distinction is sharply drawn between “the one who practices sin” in 3:8, who is of the devil, and “the one who is fathered by God” in 3:9, who “does not practice sin.” See S. Kubo (“I John 3:9: Absolute or Habitual?” AUSS 7 [1969]: 47-56) for a fuller discussion of the author’s argument as based on a sharp antithesis between the recipients (true Christians) and the opponents (heretics).
sn Does not practice sin. Again, as in 3:6, the author is making a clear distinction between the opponents, who as moral indifferentists downplay the significance of sin in the life of the Christian, and the recipients, who as true Christians recognize the significance of sin because Jesus came to take it away (3:5) and to destroy it as a work of the devil (3:8). This explanation still has to deal with the apparent contradiction between the author’s statements in 2:1-2 and those here in 3:9, but this is best explained in terms of the author’s tendency to present issues in “either/or” terms to bring out the drastic contrast between his readers, whom he regards as true believers, and the opponents, whom he regards as false. In 2:1-2 the author can acknowledge the possibility that a true Christian might on occasion sin, because in this context he wishes to reassure his readers that the statements he has made about the opponents in the preceding context do not apply to them. But in 3:4-10, his concern is to bring out the absolute difference between the opponents and his readers, so he speaks in theoretical terms which do not discuss the possible occasional exception, because to do so would weaken his argument.
3 tn Both the first and second ὅτι (Joti) in 3:9 are causal. The first gives the reason why the person who is begotten by God does not practice sin (“because his seed resides in him).” The second gives the reason why the person who is begotten by God is not able to sin (“because he has been begotten by God).”
4 tn Grk “his”; the referent (God) has been specified in the translation for clarity.
5 tn The closest meaning for σπέρμα (sperma) in this context is “male generating seed” (cf. BDAG 937 s.v. 1.b), although this is a figurative rather than a literal sense. Such imagery is bold and has seemed crudely anthropomorphic to some interpreters, but it poses no more difficulty than the image of God as a male parent fathering Christians that appears in John 1:13 and is behind the use of γεννάω (gennaw) with reference to Christians in 1 John 2:29; 3:9; 4:7; 5:1, 4, and 18.
6 tn “Thus” is not in the Greek text, but is supplied to bring out the resultative force of the clause in English.
7 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.
8 tn See note on the term “fellow Christian” in 2:9.
sn Does not love his fellow Christian. The theme of loving one’s fellow Christian appears in the final clause of 3:10 because it provides the transition to the second major section of 1 John, 3:11-5:12, and specifically to the following section 3:11-24. The theme of love will dominate the second major section of the letter (see 1 John 4:8).
