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 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 tn This ὅτι (Joti) is best understood (1) as causal. Some have taken it (2) as declarative, giving the content of the Spirit’s testimony: “and the Spirit is the One who testifies that the Spirit is the truth.” This is certainly possible, since a ὅτι clause following the cognate verb μαρτυρέω (marturevw) often gives the content of the testimony (cf. John 1:34; 3:28; 4:39, 44). But in the Gospel of John the Spirit never bears witness on his own behalf, but always on behalf of Jesus (John 15:26, 16:13). There are, in fact, some instances in the Gospel of John where a ὅτι clause following μαρτυρέω is causal (8:14, 15:27), and that is more likely here: “and the Spirit is the One who testifies, because the Spirit is the truth.”
