¹ tn This ὅτι (Joti) is causal, giving the reason why the readers, as believers, ought to love one another: because love comes from God. The next clause, introduced by καί (kai), does not give a second reason (i.e., is not related to the ὅτι clause), but introduces a second and additional thought: Everyone who loves is fathered by God and knows God.

² tn As in 2:23 and 3:4, the author uses πᾶς (pas) with the present articular participle as a generalization to describe a category of people.

sn From the author’s “either/or” perspective (which tends to see things in terms of polar opposites) the use of a generalization like everyone who presents a way of categorizing the opponents on the one hand and the recipients, whom the author regards as genuine Christians, on the other. Thus everyone who loves refers to all true Christians, who give evidence by their love for one another that they have indeed been begotten by God and are thus God’s children. The opposite situation is described in the following verse, 4:8, where (although everyone [πᾶς, pas] is omitted) it is clear that a contrast is intended.

³ tn The verb γεννάω (gennaw) in this context means to be fathered by God and thus a child of God. The imagery in 1 John is that of the male parent who fathers children (see especially 3:9 and 5:1).

⁴ 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.”

⁵ tn The two ὅτι (Joti) clauses are epexegetical to the phrase ἐν τούτῳ (en toutw) which begins the verse.

sn What is important (as far as the author is concerned) is not whether we love God (or say that we love God – a claim of the opponents is probably behind this), but that God has loved us and sent his Son to be the atoning sacrifice which removes believers’ sins. This latter point is similar to the point made in 2:2 and is at the heart of the author’s dispute with the opponents, because they were denying any salvific value to Jesus’ earthly life and ministry, including his death on the cross.

⁶ 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.
